What kind of tire pressure are you running, and why?

I'm running 26x9-14 and 26x11-14 as well at 12psi and like it. I haven't ran any other pressure yet, I have about 250 miles on these so far. I also runs lots of highway, its about a 4 mile round trip on the pavement every time I ride to get to where I ride.

I'm running 6 ta 8 psi in the outlaws and 10 in the X-lites to help smooth them out.
I'm looking at buying a set of bighorns or moto's in 14's is there any advantages over the 12'' rims?

I'm running 25x7x12 and 25x9x12 Dirt Tamers on superatv wheels. I'm running about 7.5 psi's all around. I run them that way because the sidewall says 36psi max for install, and run @ 7-8 psi.

I like the way the tire flexes over obstacles, but its still stiff enough for riding at speed. If the set-up sounds wrong, let me know.

12-14 in the front and 14-16 in the rear or i get sidewall punctures...thats for going 40 in the rocks....lol

I run 26x10x12 mud lite front @ 12 psi , 26x12x12 mudlite rear @ 14psi

It all depends on how hard you drive. If you slow down for the rough stuff to avoid hard hits, low psi is good. I used to drive that way, then I went to the JBS hot rod driving school. LOL If you run hard everywhere and only slow down enough to keep control of your ride, then you better run at least 12 all around. Sliding across a rut in a turn, or hitting a rock will knock a tire down if you are running in the single digits at high speeds. When I ride alone, or lead the pack, I run a little lower psi to get traction. If I'm in a group trying to keep up and it's fast, I run 12-14. Traction suffers, but I come home with my tires still holding air.
