Hi all

Just a quick question , when it comes to tire pressure for different terains , what should the pressure be in my tires for each condition?? :hmm:

Comments appreciated

depends on several things, mostly the tire your running because some tires handle lower pressure better then others
but as a rule of thumb, the harder the soil, the harder the pressure and vice versa

(EDIT) I had that written down wrong, when the soil is hard, rocks and roots and what not you want a higher pressure to keep from puncturing the tube
when the soil is soft, mud or loose sand, you want a lower tire pressure so the tire can flatten out a bit and have a bigger footprint resulting in better grip

depending on your weight & the type of tyres you run & the terrain you ride it varies to be honest...I like to run 12 psi in the front & 12-15 in the rear as I don't like to suffer punctures! if you use heavy duty inner tubes then you could possibly run lower pressures..again it all depends on the above.

I run 12 in the front, and 6 - 8lb in a trials tire out back.

I run 8-9 front and rear on S-12's. Any more than that and it feels "skaty", less it feels too wallowy. I do use the heavy tubes. I like to see about an 1/8" of shiny rim right at the bead.

Too many variables to suggest a tire pressure for you. Variables are your terrain, your tires, your tubes (or lack of), your riding style, and the weight of rider and bike. Pick a safe pressure, say 15 psi, and raise/lower it in 1/2 psi increments until you get a negative effect on handling or traction and then bump it back a 1/2 psi. Due this individually for each tire. For the record, the optimum tire pressure will change from ride to ride and even during your ride. Find a good compromise and run it!

This time of year I tend to run 7-8 in the front and around 5 in the rear. The Tubliss is awesome for getting those trals tire like pressures and traction! :mrgreen: I tend to bump pressures up some when the dirt has more moisture in it.

It is something that you need to figure out for your situation.

I'm 180 geared up.....dry(er) rocky (small river rock type) terrain I tend to run around 16/14. Wet and muddy I ride 12/10. In the NW dessert, dry, hard and BIG rocks, I run 18/16....that being said, these pressures change every time I change my tire brand/type. The side walls on mine are so tough I can drop down as low as 6 psi (which I will do if the riding gets real slick) and still have lots of traction and stability. Doing a 50 mile single track a couple weekends ago, I found clay mud and black slime. I dropped my pressure down to 9/8 just to stay on the trail and corner. If riding new terrain and I know the general type of dirt, I will try a higher pressure than I think I need, if it works well, I leave it, if I have traction problems I can drop pressure while riding. It's much easier than trying to air-up while on the trail.
