Thanks for the video Doddy. Highly informative.

[@cb6866]

Thanks Mr Dodd...I have to confess , I ride gravel primarily .I watch you religiously to educate my self about biking , period . It is a masters class to me , as I am fairly new to this level of cycling . Thank you very much ! Peace

[@djsonfire0001]

Brilliant video thanks Doddy!👍👍

[@matt_acton-varian]

To use your Cyclo-cross analogy in mud, yes, I totally agree. I occasionally race CX and I have 2 sets of tyres. A mixed/dry terrain tyre (33mm wide) and a narrower mud tyre with aggressive deeper tread (31mmm wide) for sloppy conditions. Narrower in mud is much better. I only ride cross-country for flat bars so I don't tend to ride mountain bike in winter.

[@ish474]

no one ever talks about sidewall when talking pressures. I switched to DH casing 2.4 DHR II'S and I can run 19psi vs 26psi on a light casing. I don't recommend DH casing because they are HEAVY I mean stuck in the mud heavy. but man they grip, turn, and brake better by a factor I never would have guessed. Thanks Doddy another great video

[@matthewlaw8268]

Run DH casing on my ebike and they are perfect but dont run DH or DD casings on my normal enduro bike. True what you say about pressures, the stronger the sidewall the less PSI.

[@TheRotundRider]

So true. My trail bike came with a trail rated tire in the back, but I progressed to start riding down more chunky trails. Pinch flats all the damn time! Even when running 30psi. Finally got a stronger tire and enjoyed a carefree remainder of the season.

[@Outsideville]

What do you mean "no one ever talks about sidewall"? You just did and others replied. Cool! Now we talked about it.

[@Liv3rman]

Great insight as always Doddy. 👍 Given me motivation to actually start experimenting!

[@hallstewart]

Great vid. Every ride has such a mix of surfaces, it's a compromise. I was always told "orange hard at the front, apple at the back" which I use on generally faster hard surface trail condition. But I typically run "Banana hard at the front and orange at the back" for more slippery squishy natch trails. On the hardtail in particular, having big tyres with an insert in the rear allows a soft rear end for super climbing progress and back relief on descending, without catastrophes.

[@cibablea]

Great info and well delivered. Thanks.

[@theavangelist]

The bit that is missing on all the historic GMBN videos is difference with and without an inner tube

[@Icehso140]

Coming from a road bike beginning and weighing over 200 lbs, (I'm not telling how much over 200 lbs), I was used to 100-120 PSI for the smaller tires to avoid rim damage. Switching to MTB I saw 60 PSI on the tire, so that's what I did. Not a good experience. Lots of OTBs. Over the years I dropped my pressure 5 PSI at a time, then I saw a video of someone running 27 PSI. I comprimised at 35 PSI and what a difference. Roots and rocks seemed to vanish from the trail as the tire formed its way over them rather than bouncing into them and stopping altogether. Who knew? Apparently everyone but me. LOL

[@OneTrueCat]

At 110 over 200, I run 40/40 on 2.2 trail tires, and yeah, anything more than that is AWFUL if you hit any kind of rough anything.

[@caiogarcia5963]

I did not until now 😂

[@briw4647]

I use 40/40 on my tyres, sometimes 38/35, rear front. I'm over 200 lbs too, uk based but with tyre pumps, I think it's easier to work with these measurements. Works well with me

[@sheldonupthegrove7822]

South Florida rider here. Trails are very technical with LOTS of roots. 2.4 Front- 21psi 2.3 rear- 23psi. Maxxis Minion DHF & DHR Made a huge difference in comfort when I lowered the tire pressures from 26/28

[@mikes4163]

For mud it depends on the mud. If it's an inch or two of thin mud over a hard surface then 'cutting through' makes sense. If it's just mud, or water on top of mud, getting thicker as you go down and down, and down ... then cutting through means you're pedalling a plough.

[@volkoff6357]

As the most influential thing you can do to your bike, it should have way more views. Great stuff!

[@marauder7412]

tyre construction and carcass make a massive difference too. On Maxxis EXO+ DHF II, I needed to run at least 24 PSI, but with Magic Marry Super Gravity Orange I run only 17-18 PSI.

[@wonderwatch2239]

Love low pressures for roots, rocks & slick conditions, but hate the road/gravel transport to and from the trails. 80 kg 2,4 tires with 20 F and 24 B. 2,6 tires with 16 F and 18 B for maximum grip on wet roots 🤘

[@p.s.9526]

I run my 2.2 conti speedkings around 40-45 psi at tarmac and love it :D

[@Magoo71]

I run 2.6" Maxxis Recon tires and run them at 18 lbs in the rear and 16 lbs in the front which are in line with ENVE's recommended pressures for my riding weight and their Carbon wheel sets.

[@zigbug1314]

I use continental double fighter 2.0’s on my hardtail. I will normally go 45 rear and 40 front on tarmac, on trails (light gravel) I will go 32 rear and 30 front. If it’s particularly wet on the trails I would normally switch out the tyres, but if I was going through mild/moderate mud I would drop again to 28 rear and 25 front

On my Orbea Laufey which has 29x2.6 inch tyres on the original Orbea oem wheels. The tyre states a maximum pressure of 40 psi. However the rim states a maximum pressure of 38 psi. I weigh about 90kgs. with riding gear and backpack I am probably closer to 110kgs. I run 22 psi in the front and 26-27 psi in the rear on my 29er hardtail. I don't have inserts in the tyre yet. On my 27.5 inch full sus I run the tyre pressures not too far the hardtail. Within 1-2 psi. I do have inserts in these tyres. They are also 27.5x2.3.

[@djsercy5879]

Since my bike is used for commuting more than anything, I run 42psi in the front and 44 in the rear. I find that it works pretty well here in SFL even during torrential rain, where I honestly feel no difference in grip. For reference, I run a Continental CrossKing (29×2.2) in front and a Pirelli Scorpion XC-M (29×2.2) in the rear

[@JudeTheYoutubePoopersubscribe]

Well, my tire pressure sounds ridicolous compared, but taking every variable in it isn't. I'm 2m tall and around 110 kg (without gear, so probably for a longer ride ends up being 115 -120 kg). I've got a Schwalbe Nobby Nic on my bike (since years, was pretty happy with it for my terrain) with tubes. So i'm running around 2.5 bar, i need this pressure to support my weight and not get a snake bite on every bigger root.

what if you use the same bike for bigger smoother jumps and also use it for rougher terrain? i.e. hard shocks/hard tires vs softer shocks/softer tires and vice versa in combinations? i sometimes I feel slow in to jumps so I pump up my tires or shock, to not swallow my travel and feel like I'm absorbing or going slow on the jumps. Is it worth running softer shock then using the lockout features to compensate when you want spring over absorb. sam pilgrim seems to run really high pressures for jumps or over leaning forward or back due to softness. I kind of want the best of both or a flick a switch solution. Thanks.

I hit 3 more bike parks and noticed when i hit a berm my front tire feels like its going to wash out. It seems sketchy AF. I tried to make sure my weight is over the handle bars and it still does it. I wondered, is it the dirt thats lose? Im running 28psi in front and back. But i noticed when i squeeze the front brake and compress the forks my front tire seems squishy. So i wondered if my tire is deforming in the turns. After watching this video and hearing what your mate said at the end. Im starting to think this is the case. I weigh 180 to 185 pounds.

Dry Conditions (similar to what you get in Colorado) I would go DHF in the front and Aggressor in the rear. Some people think the aggressor wears to fast but I think it is worth it. Those people might point you to a dissector. You can get both of those in 2.5 WT with all kinds of casing choices.

I have both tires however different sizes and different bikes. Rekon will be a little faster rolling but IMO the extra grip on the xr4 would more than make up for the negligable extra rolling resistance.

20 front and rear unless I'm on the road then hard as poss.

In this case, as a german, i prefer PSI because 30 / 35 / 40 / 45 PSI sounds much better then 1,8 / 1,9 / 2,15 bar :D
