Andrew. I’m in Georgia, USA. Your videos captivate me. Your experience is unmatched on KZbin. I love your productions and adventures, but you have “a way”of telling a story and that is what so captivating. I bought my first LC (100 series) a few years ago and I’m smitten. I would love if Toyota would bring the 70 series and even more so diesel to the US. I will continue to wish I guess.Thank you for all your hard work. BTW, I love your humor. I literally laugh out loud often while watching you.

[@StephenDavisMonsignor]

Same for me... part of the reason for my switch to my Land Cruiser (200 Series) was ASPW and Ronny Dahl... I also like the humor - about lost it here: 14:41 when he says I stop for a pee.... 😏

[@4570levergun]

As long as they are 25 years old.

[@4570levergun]

Davin, Not to my knowledge. If it doesn't pass all the DOT requirements you can't get it titled. There are a few exceptions but they are rare. Best we can do here is get a 25 year old truck and rebuild it or trick out a 80 series. Lot of info over at ih8mud.com

[@Sumitso]

Land cruisers that were not originally sold here in the US, have to be over 25 yrs old in order to import them legally. If they are newer than the 25yr limit, they can be seized and destroyed. It is a frustration to cruiserheads =/

[@gkanai1400]

Selling the 70 Series in the US would only compete with other Toyotas like the Tacoma or other US-built Toyotas. It's not going to happen.

[@wvlongshooter3912]

Finally, someone that’s makes sense on tire pressure!!’

[@jhorton1600]

About 10 years ago I operated my own semi truck and did an experiment. Normal pressures for that type of vehicle is 100psi (6.89 bar). I raised all 18 of my tires to 105psi (7.24bar), and did the "temp test" as you described. With similar atmospheric temps, miles driven and cargo load, the tires were noticeably cooler to the touch. The point is that even small pressure changes can make a difference. Very nice video/ subject matter.

[@ensatlantic]

Wealth of information on an endless topic. Thanks!

[@solracser6705]

Excelent video Mr Andrew!! this type of videos are the ones that nobody explains! Thanks 1

[@JamesGraham1971]

Excellent video series, please keep up the activities for all of us who work in an office. Almost like being on the trail.

[@AscendingBliss]

Your shared knowledge and information is invaluable, sir. Thank you very, very much.

[@joshhand9766]

Let me start out with the confession that I spent at least a few hours trying to figure out what pressure is best for my mud terrain tires while on the road. The tires I had were rated for a heavier vehicle (~1,000 lbs. or more), so I assumed I should inflate them in proportion to my vehicle. I read all the forum conversations, and I watched all the youtube. I heard a lot of people saying to just look at your door jamb, and on the opposite end there were people with some nice long equations to help you "estimate" the pressure. The only information I found useful: 1. Chalk the tread all the way across the width of your tire, and drive on flat ground (cement or asphalt). Stop or repeat, while adjusting your pressure up or down, until you only see an 1/8-1/4" of chalk at the outside edges of your tire tread. 2. Stick something flat under your tire tread closest to the bottom of your tire tread. Make sure it doesn't stick an 1/8-1/4" underneath it (considering the thickness of your thing). Adjust your pressure up or down until it's good. That's a good starting point, and then it's way easier to adjust when you're off road. That being said, I'm about 15 psi below the doorjamb, and over 30 psi below the max pressure of the tire. Sorry, I'm not going to convert to bar. My tires never feel warm, even at speeds above their rating, including above room temperatures (68 deg F). Added bonus: you get very even tread-wear. Sometimes when I'm watching your channel, I'm reminded that there are people who think about things like tire pressure/heat/footprint, as much as me, and make videos about it. Thanks.

[@robertovacaaguilar6501]

Hi Andrew, I live in Baja México, your experience have been very usefull!! I follow tour chanel forma two years now, and I have learned a Lot... Congratulations. GREAT CHANNEL.....

[@NathanNostaw]

Thanks for such informative and videos. It is good to hear opinions based on years of real-world use.

[@paulformaioni37]

good episode, tyre pressure the most important aspect of enjoyable driving

[@TheTravelingTogetherJournal]

Useful info about checking the tire temperature with your hand. I knew I didn't want them hot, but didn't know how hot was too hot. Thanks

[@denisvincent4410]

Well said , waiting for your thoughts on the tyres and the rear wheel carrier thanks

[@lanceroark6386]

This is an awesome video! That's my attitude all day every day; "how do you know." Which is followed by the thought that I'd like to hit them with something.

[@CliveWebbAustralia]

I agree 100%. I have had this discussion with so many people. The correct tyre pressure depends on so many things, the road/track/beach conditions, the temperature of the day and the kind/make of tyre you are running. It's like good drivers really. A good driver adjust the way they drive to the conditions of the day. It's the same for tyres, you adjust and then you monitor and re-adjust as is necessary...

[@landcruisertroopytouringan2166]

Thanks, great subject and you have a fantastic platform to educate people from. Maybe a few people might shock themselves and discover a smooth ride and traction during their next adventure. 👍

[@jr15wa]

in my expeience as a chaser/culler in the Pilbara..West Aussie..tubeless #1 BFG #2 Toyo #3 Coopers

[@daveybernard1056]

Hmmmm

[@nickcardillo5021]

Great advice Andrew. I burst a sidewall on the Madigan Line in the Simpson Desert from running pressures too low. It was a combination of factors - tire with flexy sidewall (Toyo All Terrain), heavy vehicle (76 series fully loaded at beginning of expedition, near GVM), travelling too fast over gravel and dunes on a hot day. As a result the rest of the trip was very precarious without a spare tire. Lessons learnt: heavy vehicles require a stronger sidewall, monitor the tire temperature manually and sidewall flex visually rather than relying on purely on a pressure gauge. Invaluable lessons learnt the hard way.

[@benjohnson1082]

Great video Andrew! That was a great way to cover the material.

[@mountainconstructions]

Great subject matter

[@kyleh6802]

Airing down does do wonders for comfort but it's very true that too low can cause damage, regardless or size or type and the pressure is completely subjective. I had large off-road tires with good heavy sidewalls that I aired down 2 weeks of every month for work on rough roads. When I got pack to the main road after my week on the dirt I would air back up. One day my wife was driving my truck in the city with the tires at full street pressure and thankfully just after she parked it one of the sidewalls exploded! I swapped on the spare tire and 2 days later a second sidewall exploded while I was driving, slowly fortunately. I am much more conservative with my pressures now. Don't be fooled by anyone on the internet saying you should air down to x pressure, even if it's the same vehicle. Thanks for the videos, you share a lot of knowledge.

[@williamkeating6406]

Once again thanks for the very informative information on tire/tyre pressure. Bars are easy I think atmospheres 2 bar two atmospheres or around 29PSI + a little.

[@mindofown]

great wisdom

[@veselingramatikov]

For me interesting will be comparing sizes vs truck weight. So far this is your first proper video abt tires.

[@505xjk6]

Love your videos Andrew..I have run 1st gen,2nd gen,3rd gen BFG mud terrain tires .love the first, second gens. the 3rd gen did no wear evenly even with 3000 mile rotation's.I'm waiting for release here in the states .keep up the honest reviews ..

[@uaeoutdoor8030]

Andrew, please do touch on beadlocks wheels in Part 2. Keep up the good work mate. Love your channel.

[@gerdacoonan7250]

Interesting subject Andrew, well covered in your usual thoughtful and experienced way, very enjoyable. Thanks, and enjoy the rest of your odyssey, looking forward to more, cheers. PS, in your next clip on this trip, could you mention in the description the camera you use for these sessions, . . or will that be a separate subject matter ??, thanks.

[@ericrogers7797]

Thank you Andrew! Get the comment on “your tires are too hard”, just had that discussion over the weekend. Haha.

[@MrScalman]

great video. one thing that i not heard of in other places look at your tires. look not just have list with pressures you should run on bush or on road. all forums just tells you : ohh you need this much bar offroad and this much onroad. its very good point to look at tires. i was looking at my BFG Ko2's and saw how much it flexes. very good video. little short but good. waiting for part 2

[@brianmorse8811]

I run a Kevlar tub on the inside at a different pressure from my tire on the outer. It holds my tire like a lock ring. 40 psi inside and 16 psi outside. only on the trail. less air to add when I hit the road. Works unbelievably! from the States.

[@brandonrawlings7775]

Love this video

[@DaneF1]

You were thinking of Ade Larsen when you said someone will disagree with you about tubeless tyres?

[@stevecrawford6080]

I bought four used all terrain tires BFG; put them on my blazer; aired them up 15psi; ran them over five years in and out of the desert; still had deep tread on them (they were just all chunked up) when I decided to put four BRAND NEW TIRES on it (different brand mud terrains 10$ cheaper per tire); aired them to 15psi, three of them blew out the side wall within six months; dad-gum-it.

[@xtremeboyable]

Great Video. I have gu patrol and I did a lot of sand driving with 1 bar pressure, in two occasions I had to drive on the pavement for 30 KM to find air pressure to inflate my tyres, what happened? Two tires had deep dangerous cracks in sidewalls; I replaced them . So I learned I let the tires only when necessary and preferably drive low speeds and never ever on pavement.

[@paullangenberg5907]

I travel the Australian outback a fair bit and am still amazed at the amount people not willing or just ignorant about lowering tire pressures

[@pietskiet8763]

They are the ones that cause washboard ruts in any terrain , on all my safaris , I meassure each vehicles tyre pressure with one gauge .

Easy listening with Andrew St Pierre White.

[@applesbighatranch6906]

At 1:57 - :58 into the vid, I kept wanting to hear you say instead, "When running low SQUINCH..." which as we all know is to achieve a greater SQUISH... a longer tyre contact patch... by Jove! I believe I'll shut my yapper about now.

[@willcowell8197]

Very informative! I have a question: In your experience what tyre pressure is best suited to rugged off road terrain and areas with a lot of big acacia thorns? As a conservationist in Kenya I work in the bush everyday and even though I have bfg km2 mud terrains I still get punctures in the sidewalls from thorns that I don't see while driving offroad/ on bush tracks. From the many places you've been to in Africa, you might be able to relate? I haven't seen the topic of thorns, specifically in African wilderness areas, being discussed much on youtube and I would appreciate any feedback.

[@michaelrowse4917]

Thanks again Andrew, enjoyed the post. Tubes vs Tubeless, they are different animals; The tubed Tyre/ rim shouldn't drop too low, tubed tyres don't grip the rims well, the Tyre can spin on the rim and rip the valve from the tube. Tubeless Tyre with a tube fitted, a great get you home option but in normal use generates extra heat between tube and Tyre for which it was not designed. I liked to operate in rough terrain with high/ std pressure, I felt it resisted damage easier. In soft sand, KSA, UAU, Oman etc I used low pressure and judged the exact pressure just as you mentioned but checked pressures to match on the same axle. Reality Check,,, we are all so knowledgeable and educated,,, :-) I was enjoying a day driving over soft dunes in Saudi, Jeep Cherokee, 4x4, loads of available power, we were right up there, top of the dunes, 50 miles from the nearest track, great fun, proud as punch. Until. Along came some Saudi lads, teenagers, driving a Toyota Cressida, (2WD) towing a carpet on a rope, with more kids sitting on it, having an even better time :-) The Cressida was ancient, tyres completely bald, almost dead flat. But! They were going easily where I was struggling. Loved the encounter, they were impressed that we even got there, I was even more impressed with them. We shared a few cold cokes and went on our way. Lesson learned, never take myself too seriously, these lads could REALLY drive in the desert, I was a visitor :-)

[@michaelrowse4917]

If I may add one extra comment. Picture the scene, Outside of Jeddah, 2000s ish, a nice area of soft sand, often frequented for day trips. Brand new, unregistered VW Tuareg, around the time of the launch, 'high ranking brand official decided to take 2 x friends of the female persuasipn into the desert for a demonstration. I get a call, come get me out. 1, single vehicle? 2, stuck deep in a sand bowl resting on front and rear bumpers, 3, tyres at 'pre delivery pressure' 60 PSI! 4, not a bottle of water between them. 5, single guy, 2 x unrelated single women in a car along, not allowed in Saudi. Dragged it around until free of the bumpers, pressures dropped to minimum possible, a little tug with my vehicle at the time (S2 Disco) and away we go. Lessons learned all round, even a Tuareg will perform if set up and driven well. The names have been withheld to protect the guilty ;-) Thanks again for your posts

[@Photoharv]

what type of tires would you recommend for someone who plans to drive more on asphalt, say 70% of the time, and the rest between beach sand and gravel? BF Goodrich KO2 o wait for the KM3? MPG are no issue.. just want the ones that last longer and give a best performance...

[@bigjml]

I watched one of your videos where Armour Seal was used in the tyres. Would you consider it a good idea or would your preference be carrying a tubeless tyre puncture repair kit?

[@simon762321]

Any chance you could link to the video of the Discovery on the Canning?

[@hintersland7262]

Andrew, have you had any experience with Michelin XZLs? Thanks

[@GregMcDavid]

Not sure if you mention it in the second video, but what are your feelings on tyre pressure monitors?

[@sonictech1000]

I'm sure you mentioned it in an earlier video but how much did your rig end up weighing?

[@danmacka4425]

Hi asp I’ve got tpm and it measures heat. What kind of heat do you think rings alarm bells. 50, 60 degrees or even 80? I find with just hot weather they can get in the 40-50 range even fully inflated. Also on hwy speed in a big car I’ve got a lc200, on 33” what rough pressure would you suggest. I normally go say 42 f 44 r? Thanks a lot. Enjoy the big trip mate.

[@gregculverwell]

Hi Andrew, would you happen to know what in °C is too hot?

[@cliffbernsen438]

Do you prefer higher, middle or lower pressure with a skinny tire in mud? 235/85r16

[@wissamkarime5339]

How's the trip going mate?

[@pietskiet8763]

The mud -terrain's aggresive profile quite often saves the day , for that last little bit of extra grip just to creast a dune , when you are the lead vehicle , or recovery ! In the Namib.

[@benwilson9145]

I’ve been watching a lot of your older solar related videos and I’m wondering if you have ever thought of or tried to put wind turbines on your vehicle to charge your batteries. I don’t even know if they exist but I can’t see why not.

[@chrisoncars8820]

Andrew, here in the states I have seen people carry a tube to repair a rubeless tire in an absolute emergency situation whereby a large cut is in the tire and prevents the push in plug type repair . . . have you seen this? I have also seen people stuff the tire with grass, etc . . . .just to fill the tubeless tire to get out of the bush.

[@mark2073]

How often should you replace the air in your tires?

[@pietskiet8763]

Low pressure tyre damage can also be seen when you have the tyre off the rim and stand it upright , driving position for the tyre , and applying pressure from the top , if small cracks appear in the now folding bit of the tyre , at the bottom , its busy going !

[@billhodges6547]

I remember dune buggies back in the day using wide racing tires with no tread. Worked great in the sand and didn't dig into the sand.

[@brandoncser2842]

What happened to part 2? I can’t find that video

[@hatblocker]

ok, what tubed tyre is as strong as an MRF 7.50 16 16 ply road pattern or super lug ? all us mugs out bush must be missing something

[@ajn.mychannel4864]

We have recently bought a Prado and it has stock tyres on it. Do you think it will be fine for some mild four wheel driving without getting new tyres designed for off roading. (it will be used on road 90% of the time so I don't really want to get new tyres unless it is necessary).

[@TheTravelingTogetherJournal]

I realize your looking for Andrew's opinion, but he doesn't respond often, so I figured I'de give you my 2 cents. A good street tire will do fine for mild off roading, particularly on dry dirt, gravel or sand. They will not do well with mud and they are not as robust as an off road tire, so you need to be more careful with them. Breaking traction or rubbing the sidewalls will be more likely to result in damages. I would recommend making sure you have a good, full size spare and sticking to your street tires to get started. If you find yourself wanting to adventure out where your street tires are too much of a liability, then it's time to consider some all terrains or maybe even some mud tires depending on where you live.

[@ajn.mychannel4864]

I wasn't looking for Andrews opinion actually haha, (although I do realise that I have worded it that way, so my bad). Anyway, thanks heaps for responding. I had a similar opinion to you on the subject although I did want to check with some other people. Thanks for the response :)

[@garrycrobbins]

i have had a rep for BFG and 3 tyre centre owners tell me to never run my BFG AT under 45PSI. I have a Defender 110 and loaded for a long trip weighs just under 3 tonne. All people who suggested the minimum 45 PSI said that lowering pressures on rough dirt roads and corrugations will be more comfortable but the tyres will last longer at higher pressures. I run mine around 50 PSI in most conditions.

[@RagingBlock]

Hey Andrew, will you be at Abenteuer Allrad in Germany this year? Love the videos, cant wait for the trans Australia footage !

[@cpgeorge2518]

Can you talk about the same type of tire, in the same height, but different width? Like what the advantages and disadvantages of skinny vs wide and what terrain they work best in? Thank you!

[@King88_8]

cpgeorge25 thats the comparison currently being done on this trip. Report at end of trip

[@032254855]

run bfg km2 MT on my defender 110 what tyre pressure would you recommend for river beds with stones about fist size up to around 2 to 3 times the size of a basketball. Truck is never loaded too heavy normally i drop the pressure to about 18 psi / 1.24 bar but notice a lot of marks on the side wall i used to run 33 psi / 2.27 bar and didn't notice as much marks 33 psi is what i run on the road

[@JimmyStewpot]

Brown Bomber I have a similar setup and run 18 on the front and 22 to 24 on the rear

[@edwardpeters4700]

I find I'm more concerned with balancing my tire pressures than a specific number. It actually matters on my WRX to keep the diffs healthy (in addition to a matched set of tires) so the habit persists across the board (doing the same with my Gen 2 SWB Pajero).

[@davidrandall2742]

Tubeless radial vs tubeless bias ply not mentioned. If I'm correct, tubeless bias-plys have more vertical sidewalls, and resist punctures better. Not great for the road, of course, and can't balance them consistently.

[@nathansharma87]

Hey Andrew, whats your take on the thought process on tyre pressures around sharp rocky outback roads like the Flinders or central Australia? The late great Jack Absolum who travelled much of Australia in a Mitsubishi rwd station wagon always kept his inflated at highway pressures to avoid the sidewalls being staked. Of course we have stronger tyres now, I'm kind of on the fence here. 99.9% of people say drop em down, but in my experience you'd have to take a hydraulic spear to the tread on a modern all terrain in order to puncture it but the sidewalls are still vulnerable. Personally I go low for traction needs but rocks, corrugations etc I just run highway pressures. Comments getting longer than I expected but I also worked somewhere that rented mine utes and survey utes. They would get absolutely bashed in the worst places for thousands of KMs, we had whatever all terrains on them. Only one had the BF KO2, some Kendas, Kumho AT51, cheap Chinese brands and they all survived. The operators never stopped to adjust pressures, they just plant their foot to the floor and hammer through different sites and states. We had tyres with loads of cutting and chipping and scallops ripped out of them at just 10-15k but very rarely a puncture. Just thought I'd throw that in you might find it interesting.

[@4xoverland]

I agree totally. Watch my Discover trip in Lesotho. I kept them hard to prevent sidewall damage and it worked even on 20" rims.

[@alex.4753]

I love this guy and his sass to people who mindlessly comment on peoples pressures 😂😂

[@mikeburston9427]

Hi Andrew One thing you didn't mention with tyres getting hot when you let them down is that the pressure may be correct but the speed you are driving is too high. This is a very common mistake with people that they let air out of the tyres and then want to push along at the speeds too high. As a quick rule of thumb for my vehicle and tyres when fully loaded to work out how fast i can go i multiply my pressure in PSI by 2.5 and that gives me a max speed in km/Hr eg 10 PSI x 2.5 = 25 km/hr.

[@sonictech1000]

Mike Burston Sounds like a pretty useful rule of thumb.

[@sonictech1000]

Mike Burston Btw, how much does your rig weigh?

[@mikeburston9427]

last big trip was about 2800kg running A/T 265/75R16 with pressures from 10PSI to 60PSI depending on terrain and front back weights

[@mikeburston9427]

Yes you are right i did miss that Must have been distracted . Although Andrew is talking about tube tyres there it also applies to tubeless as well

[@sonictech1000]

Mike Burston Thanks. My truck and camper weigh between 3700-4000kg. Although I never thought about it in terms of a psi multiple, in practice I've been running about a 2x multiple. Basically 70-80 psi for highways, 50psi for good dirt/gravel and 35psi for anything that involves a lot of low range.

[@mikeboone4425]

Great chat you mention the tubes repair kit. The inventor Arron Fromberg. I should say there could be more than one patent on tubeless tire repair just don't know . Any way the guy was clever had a machine shop at his home in Frazer park California all doing some had many patents any way when should that proto type to my dad and I it was something he had a manil steel tube cartridge with rubber some how molded in to it under tremendous pressure you just slide this tube into a crank handdal and crank this rubber, got push out of the tube into the tire and expanded I believe some 3or 4 times it's diameter may be more . But when he did not put it into the tire just to show us it look to me and dad like it was at least 5 times the original diameter of the 3/16 inch tube the rubber cam out of it was huge .Any way in the middle of all this he passed away heart attack and his wife sold the writes to it his patent she did good deal smart woman and the rest is history we never saw this item on the market like he showed us so have no idea what happened . Just a note of oddity . happy trails

[@slowboat6021]

Yes of course I have really big mud terrain tyres, don't go off-road mind you might get them dirty. But my my they do look so tough. lol sorry could not resist. truly I love your videos Andrew. please keep using bar, drives me crazy those stupid imperial measurements, FFS most of the under 40's have never seen a pound or an inch in their lives.

[@christophersaul]

Interesting comment regarding the sand driving in Namibia and the mid terrains. Here in Dubai the desert safari companies all use Land Cruisers and use standard H/T tyres. I wonder what mileage they get out of them? Every day they are used to collect customers and then spend a couple of hours’ dune bashing.

[@pietskiet8763]

Money , they have it , we in Namibia dont have their wealth. They change tyres every year , because its very low cost to them , we have to travel +_ 400 km to get to the dunes , over rough gravel roads , fully laden for those long dune trips , mud terrains last up to 3 years for us .

[@christophersaul]

piet skiet Thanks piet skiet., interesting. One day I hope to drive those dunes in Namibia myself.

[@juanpinto3323]

Andrew being in the Greater Kruger in the african bush With Landrover’s and Landcruiser tubed tires are for the dark ages ever time a new tire suppler what’s us to use Tubes and a tell them get lost, so for 19 years no tubes the Trackers that fix the tires thank me all the time.

[@TJA86]

The only problem with just 'looking' at your tires to determine the right pressure, is that if your vehicle isn't sitting on flat terrain, and it rarely is here in Colorado when you start to air down, you will never get close to even pressures. I'm sure it works great on a flat road, but otherwise you need some sort of measurement to keep things equal or you will end up, as an example, with the front right at 10psi looking the same as the left rear at 20psi. Just something to consider at least.

Dark ages are the days that some people bought Series Land Rovers which had rims that were riveted. Had to have tubes or else there were leaks. Anyway, if you have one of those, it is better to invest in better rims.

[@kalbarriseafrontvillas2859]

G/Day Andrew, I really enjoy your videos. I would like your opinion on, do bigger tyres, 33 inch compared to say 30 inch tyres give you a better ride on corrugations . We have just done the Great Central Road, Tanimi Road, Bungle Bungles and CSR from Halls Creek to Kunuwarritji. We pulled out at well 33 because it was to wet further south. We were travelling in a 79 series Land Cruiser with a standard front suspension, the rear has a two inch lift 450 kg West Coast Suspension with brand new 285/ 75 R16 33" Kumho tyres. We had no issues with any part of our set up. I was talking to another guy who was travelling in a 20 year old Land Rover with 4 coil spring suspension with 30 inch tyres who did a similar trip and also pulled out at Kunuwarritji and he said the corrugation were very bad, except for the 30 km each side of Kunuwarrtji which were horrible. Wondering what your opinion is or if I am barking up the wrong tree or barking mad. Regards Jamie

[@cliffbooth7075]

I did 3 Cape York trips fully loaded to the hilt with 18 psi in Ebay bought Chinese mud terrains and they performed just fine. I belted along at 90-100km/h the entire way along the PDR and they rode beautifully. Tyre size was 265/75 R16 LT construction. Very minimal damage to tread. 2 very small chips taken out of 2 tyres. The tyres were $180 each and every bit as good as name brand rip-offs selling for $350 each which I have also previously used. I just see no sense in spending double on tyres for what I could buy them for that do the same thing. Did another remote trip on another set of EBay tyres some years later with same excellent results (brands were Goodride and CF Comforser. Running too high pressures in tough conditions (stoney & corrugated) is bad for them and causes damage. I’ve been off-roading for 14 yrs and have tweaked many things along the way & have without a doubt found running lower psi to be the safest option on high speed rough tracks as the car feels nice and stable and won’t slide out on me as easily. I’m more in control and the tyres don’t have a mind of their own so much. I like watching your videos & am a subscriber to both KZbin and your podcasts, but feel you made up a lot of the content of this video without having the proper knowledge first hand about tyre performances. Never have I ever in my life experienced a tyre that got “hot” while driving even for extended periods on high speed rough corrugations or in boiling hot sand. Warm yes, but not hot as you say. I have also driven Fraser Island dozens of times in January/February and 5 Mile east of Rockhampton so many times in summer also with 18 psi and even those same pressures when I first had ordinary hwy terrain and with a 800kg payloads. Although the LT tyres handle the weight much better. Sand is kind to tyres.... Especially really soft sand because you’ve got full sand cushioning supporting a bit of the sidewalls too, in addition to the tread blocks and in between them. It spreads to load even more evenly. Hwy speeds on stoney corrugations.... Not so kind. But to me it seemed like your extensive knowledge on the subject was a little lacking in accuracy on this occasion. If you’ve been there and done it, then you’d think you’d know what is accurate information & what falls short of being accurate.

Brett B2 I've had 4wds with cheap tires and had mixed results across the same brand you mentioned. I had two sets one was rock solid and got about 30k km before replacing.. the others had sidewall blistering badly after driving on soft sand at 40c, the two opposing tires got so hot that it was uncomfortable to touch. I've since moved back to BFG's. I wanted a consistent experience. Given most of my time is away from crowds totally alone it is the one quality that I value highly.

[@cliffbooth7075]

Must be rebadged Coopers by the sound of it haha. With all the tyre problems you hear of out there, tyres getting so hot due to low pressures they melt or blow out is something i would still consider an extremely isolated incident and certainly not a common risk by any means.

[@King88_8]

Brett B2 you might not have gotten the "too hot" experience but there are many that do.... And dont realise it. Evidence of disintegrated tyres exists on many washboard trails. Thought is that mid pressures are good, lower pressures are even better. Last week I just had a guy tell me he can go down to 0.6 bar on corrugations because hes running 3ply muds on his Jeep and theres little to no flex. He will be towing an 1800kg trailer as well on a 5000km round trip. This topic is exactly like motorcycle track riding tyre debates.. Akin to religion and politics. My simple philosophy is 99% theres always only a workable window, with main parameters being , weight/terrain/temperature/driving style

[@cliffbooth7075]

King, I completely agree that driving stile plays an integral part with almost everything that can fail or wear out under a car. Steer sharply with say 10 psi with decent momentum and you can roll a tyre off a rim. Or carrying excessive weight with very low pressures can also do this if you’ve watched Ronny Dahl’s vids. They’d rolled tyres off rims in their heavily loaded cruisers. But doing damage at 18 psi unless you have a lowish profile sidewall on a 17 inch rim for example, I would say is extremely rare and o would consider that a low pressure. 18 psi is my automatic go to pressure always for off-road driving of any kind regardless of the weight I’m carrying. With quite a few different sets of tyres and the tyres have never gotten warmer than warm. I’ve heard of plenty of blowouts in over inflated low profile tyres in Darwin for example on really hot days on boiling hot bitumen. I had to do a conversion from bar to psi for your comment about 0.6 bar on corrugations being 8 psi.... And to respond to that, I think that’s not a good pressure. Way too low. But my argument was that Andrew SPW mentioned several times that if u let your tyres down “they’re going to blow” or cause damage & problems as though it’s a regular occurrence and I would have to strongly disagree as that’s a false statement. He also mentioned at one point that 26 psi was “low.” I would say 18 psi on a 16 inch rim, non-low profile tyres is safe as houses at high speed on a rough track. Lower profile tyres which many new 4wds are fitted with as standard these days.... Well that opens up another whole can of worms with potential issues with traction and tyre damage. ASPW talked of lots of blow outs experienced from low pressures but I find it hard to believe. If people are frequently running 7 psi and driving at speed then that to me is not a good idea as that’s way too low. When ever you see a 4wd with a shredded tyre on the side of a high speed rough track it would almost always be because they were running to high pressures and severely reduced their puncture protection as a result. Too high for the conditions & speed on rough tracks with puncture risks leads to tread damage too. It they had quite worn tyres, or they had a standard highway tyre without added puncture resistance. I’ve seen this scenario a fair few times. Lower pressures are safer. Not 5-8 psi low as that’s dangerous and at the extreme end of low and not too many everyday people run that low, but lower pressures are definitely safer & enable safer control of a 4wd.

[@gaj5701]

Probably a bit late for this mini-series, & maybe from a different standpoint, but can you put a bit in about still dropping tyre pressures on vehicles with traction control. Especially on sandy desert tracks as I recently watched a guy struggling up a single tracked sand dune, scalloping the living crap out of it. He hadn't reduced his tyre pressures as he apparently had been told he didn't need to because of the traction control so had taken about 30 attempts inching his way up what is actually a pretty easy dune, chopping it up as he went. He was pretty flustered & didn't want help so just bashed on until he got there, & then the small crowd that had accumulated had to drive in the mess he'd made. Not cool & horrendously misinformed.

[@King88_8]

GAJ You get thus often, including experienced offroaders and many with Disco 4s. Nothing wrong with an extremely capable vehicle, just the drivers.Yes you do drive slightly differently in some circumstances, but essentially they believe you need wheel spin to engage TC and get up an obstacle. Eventually they get up an obstacle or path but have wrecked the path/environment for those following. Pretty annoying and you can never suggest anything to them

[@hannahmillar1692]

Why doesn’t anyone tell what the highway psi is and only tell the off-road if people go off road it’s important that they inflate there tyres to a appropriate psi on the highway as they will be travelling at highway speeds and with the wrong tyre pressure on the highway it can be fatal

[@ElisPalace]

If you know how to change tyres properly or have ever worked in a tyre shop you would know split rims are not easier to change. Even In a work shop with all the machines and gear split rims take literally twice as long to change. And it doesn’t matter how strong the tyres are if you have a tube you could get a tiny rock between the tube and tyre and give you a puncture because the rim isn’t sealed I’ve changed so many tube type tyres that had sand in the tyre that’d work through the tyre

[@ovzification]

From minute 10 - 11 had me laughing, you’re mad at people making a judgement call on tire pressure by simply looking at the tire and then you go on to say thats what you do... teach us how please☺️ just kidding. Love your story telling, and if you’re still in the Simpson wnjoy👍🏻

[@4xoverland]

That's because nobody can look at a tyre and make any kind of accurate assessment of the appropriate pressure, not knowing the vehicle's weight, the thickness of looseness of the terrain, - AND, all that from a moving image on a small screen when one can see the tyre far away, in two dimensions, at one angle. Its an absurd suggestion that anyone can.

[@ovzification]

You are forgetting that your videos are of excellent quality Andrew. Its so good, I can taste the coke when you drink it... 😁 I was just making an observation thats all.

I think you are really over thinking this all. The difference between a 255 and 305 wide tyre is so negligible (20%) I don’t think it makes enough difference to even discuss. Buy the tyres that look good and fits your vehicle. And is rated for the load you need to carry of course. A better video topic would be discussing the pros and cons of getting taller tyres, and why the state of Western Australia is so fearful of big lifts and tyres.

[@robertmillar2037]

Not just width - the weight of the tyre also goes through the roof the wider you get

Why mess with the calculations the engineers did for the vehicle , most of them are VERY good !

[@rickreyes5230]

Main concern to me is popping the bead when lowering tire pressure. Other than beadlocks, does the choice of wheel reduce the chances of that happening with lower pressure tires?. Good tip on keeping front wheels straight so tires stay on bead.

[@joshhand9766]

IamTranslation Even if that's not true, I believe you.

[@markjennings2315]

I think we spell tyres as tyres from the fact that pneumatic tyres were first invented/produced by Michelin of France who spelt it that way, so we carried on from there as a courtesy. To us 'Tires' is a state of physical fatigue :-) As Andrew is English by birth and South African/Australian by residence he should spell it Tyre. Interesting that he has not??
