Very good explanation and reason here.. thanks for posting this it took the mystery out of the differences between different levels of airing down and how much. Great vid !

Great info and video, Thank you for sharing!

[@kx8960]

Nice! As a wheelin' "noob" here in the (Southwest) States, I'm trying to get the proper gear together. I just bought a new 2024 Chevy Colorado ZR2 ("Zed Ah Too" for my Aussie Mates! LOL) and found airing down with a gage a TOTAL pain, airing up with my new compressor was easier. So, I bought the Staun deflators. And since I'm more an "overlanding" guy rather than a mudder or serious rock crawler, I've decided on 28 PSI so I can run at the higher speeds the ZR2 is also good at. Thanks for the vid, this stuff really helps us noobs!

6psi was perfect for my Coily Sierra at Blacksmiths 5 weeks ago. 8psi at Stockton 3 weeks later the zook was working harder to get though the soft stuff. Just going to start at 6psi from now on on the sand...

[@4weeksleave]

Thanks mate good advice

[@Quesnel4X4]

Snow wheeling I run around 7 psi to get good traction. Every vehicle is different. The lighter the vehicle, the lower you can safely run. Tire size also comes into the equation.

[@DesertMoon]

Fantastic. Thank you.

[@MichaelLowsby]

Congratulations for the demontrations of tire pressures and it uses. Very didactic!

[@kx8960]

"didactic"

[@BHIArgentina]

Here in Argentina I've got a Chevrolet S-10 (Holden Colorado for aussie market) base model, and single traction. I put 10psi in each tyre and driving in second gear I can drive in soft sand. Of course, it's dangerous for the tyres and It isn't recomendable, but I'm poor and I love go to beach :D

[@jacedowns6643]

10 psi very low. 16-18 should get you anywhere get yourself Staun tyre deflators

[@carlosamigosAUS]

10 is fine as long as it's only sand

[@user-zh6be6jv1c]

I should have watched your video two months ago. I hit the beach in NC USA with my super duty F350 pickup truck on 80 psi. Immediately I got stuck. I had to lower the pressure to 18 psi to get out of the soft and deep sand. 20 psi didn’t work. Thanks for the education!

[@himesjon]

Is that a tow rig also? What size tires do you have

[@AL-nt3zy]

Really good generalisation of tyre pressures and driving on sand. Should be shown on loop to the 4WD'ers on Fraser I have been watching.

[@deadpool3636]

Awesome vid

[@bendgeddes]

I like 20 psi. It seems to get me where ever I’m going (4x4ing) especially all over a dry and soft Frasier Island and leaves room to go a lot lower. Great clip too. That straight forward “hill climb” demo is ideal👍

[@jayspain]

Also good on steep hill climbs or when tires are down at 8/9 to turn the AC off. Its actually noticeable.

[@garyw8362]

one thing you didn't mention that makes a huge difference is the elevation you're at. If you start at sea level and climb into mountions you will have a drastic difference. In the mojave i've started at 1100' and travelled to 7200' and had my preasure go from 12 up to 23psi. big difference

[@joebowd4726]

Especially on soft rough surface sand.low pressure in your tyres allows your tyres to roll overlump mounds of sand etc.instead of forcing though the samd.think of it as eliminating the wedge in front of your tyre.

[@Eric-tq3vn]

Do Aussies spell "tire" as "tyre?"

[@IanSR1970]

@@Eric-tq3vn Yep.

[@plantpower3048]

If I have 20 inch wheels, how low can I go in rock and gravel? Does it also depend if I have all terrain or all season tires?

[@ozflyer1]

Ive driven on Teewah at road pressures heaps of times never got bogged but then I avoid the chopped up soft stuff. Cant do it now as they have changed entry tracks.

[@kman6482]

Good example.

[@Joe-de8ye]

I have a 3500 chevy silverado 2022. What do you recommend for driving sand and mud pressures?

[@malvane8306]

i have a 90 series prado. and i only drop tyres to 20 psi and i have never been bogged on the beach

[@georgesimmons2946]

Well the beaches you drive on must be hard, in WA you would be bogged in no time with 20psi.

[@phantomwalker8251]

IT DOESNT WEIGH ANYTHING.!!.try 4 people,full gear,trailer,,bit different..

[@rikuskruger5407]

Hi i am running a 20INCH would the tyre pressure be the same ?

[@EreksonJ]

3:33 lol

[@Mr35Billyboy]

you mean on the road we have to drive our tires with 28psi air pressure. But in the video with the sand, you have road air pressure 36psi which is correct?

[@user-qz3ky2nm4i]

Glad thats not my tape measure 😂

[@mark2073]

I think there's more to it than just the length of the footprint. If it was then you'd only need a bigger tire and you wouldn't get stuck. It also has to do with tire shape. Hard tires will retain their circular profile and dig in but flat tires will conform and become flat on the bottom so they don't dig in.

[@JoshuaHockley]

Facts

[@Froggability]

You got it, I describe it low pressure the Tyre reshapes like a bulldozer track, high pressure the tyres become like bowling balls in the sand

[@zainabe9503]

that's what I thought as well. Being only 5 cm in difference I don't see much of an effect. But take that moulding conforming property and it GRIPS.

[@tjtg]

you drove through the same tracks ? And there are so many variables 16psi on my 18's ????????

[@zachandtomdad]

I have a 4 x 4 Mercedes sprinter that weighs between 9000 and 10,000 pounds fully loaded. Recommended tire pressure is 46 psi front and 67 psi rear. Obviously, dropping both to 16 psi is probably not a good idea with a vehicle that heavy. What would you recommend for sand driving, should I drop the tires by approximately 50%, or, is there another rule of thumb when dealing with a heavy vehicle and different tire pressures between the front and rear?

[@4wdsupacentreAu]

Hi Jeff, Because you have a bigger car and more weight, It may be an idea to start around 22-24 PSI on beach then go from there. If you need to drop a little more, you may but I would say avoid going too low as you wouldn't want to run your tyre off the frame. Cheers, Saleha

[@zachandtomdad]

@@4wdsupacentreAu Thanks for the reply. Just clarifying, you would recommend 22-24 psi even for the back tires which support more weight?

[@4wdsupacentreAu]

@@zachandtomdad Hi Jeff, for front tyres. Then initially a bit higher for back but I would recommend doing the test to see what exact number works for you before you drop too low. Cheers, saleha

[@RainchildAdventures]

Do your pressure numbers for various terrain apply to a truck with a 9400 pound gvwr like a Ford F250SD?

[@rockie307]

The heavier the load the more you need a rough estimate in my experience with same truck would be 15 psi minimum only if necessary for short distance at slow speeds. 20-30 for fairly rough trails with rocks depending on speed and how bad. Regular dirt,gravel roads at moderate speeds around 35 psi.

[@bradk7014]

What is the profile of these tyres? They look like 18s?

[@carlossalazar2164]

Normally run 10 to 15 psi doesn't matter the terrain normally at 10psi if it's really rocky no bead locks

[@brandanfiederlein3390]

Of course you were gonna make the third try, you basically already packed the sand firm

[@glorifiedg9582]

Yeah, about that. It might be more interesting in a new path.

Question when you decrease tyre pressure on sandy soil, does it decrease ur ability to turn sharp turs

[@4wdsupacentreAu]

Hi there, It shouldn't decrease your ability to turn. Regards, Courtney

[@tyrell_r]

@@4wdsupacentreAu thx ima tell my dad bought this, in my country its sand like the beach with tree shrubs sometime. also what is the best psi for normal tar road?

[@marctonnacliff6810]

I have high pressure tires 80 psi for road driving, is it safe to lower them to 16psi? I worry about damage and breaking the tire bead on the rim.

[@briliankamil4594]

what did you drive? 80 psi is usually its maximum presure under full load, its not for empty driving.. i you gonna air down at fullload, just see the tire when you deflate it, 70% of its original height works fine to me

[@REVIEW_JUJUR]

*I drove trough mud with 36psi = Stuck* *When i lower to 23psi = No Stuck* *I see in 23 psi, my tires are so long deflated in the tarmac (longer footprint), but sacrifice some ride height.*

[@husnainanwaar1992]

i recommend 45 psi on roads if carrying heavy loads 70 psi

i have only ever gone down to 30 psi for the beach and never had any issues

[@wam7484]

Dune sand -- 5psi. Everything else 8psi. Up to 15 if I want to mix in some highway driving between trailheads and the trails are easy.

[@danielsnook5029]

Smaller wheels equates to more sidewall.

[@lucatroiani2654]

Great video, but did anyone else lose their mind when he just threw his tools on the sand!?

[@jayodon67]

That's the difference between purchasing your own gear and having sponsors supply it!

[@petemiller519]

Dude, good video. Your tires are too low profile for a good tire. You want a large sidewall, that way it will be far more effective when you lower your pressure. I have 35's with 16 inch rims. A tire like that is far better for off roading than a 20" rim you see on a lot of mall cruisers. Try sand around 9 psi. 16 psi is still pretty high for loose sand. I think you'll like it. Cheers.
