I ran 35" XTerrains once. They lasted almost 13k miles. I thought they'd last longer being radials. They did good on the street as far as manners/handling on dry pavement. They were noisy but I don't gripe about tire noise..........in fact, I like it.........some people don't though.
In the pic below, all four tires are spinning (front & rear lockers) on the rock & I always aired down to 8-10 psi. They were soft but yet they didn't grip the rock. Prior to that set, I ran BFG M/T's....................Never spun a tire on that same rock. After the ProComps, the TSL's never spun on that rock. After the TSL's, the IROK's never spun on that rock. Also, during snow wheeling, the TSL's, BFG's, & IROK's, got me through it. The XTerrains made me hook up my strap to my front tow hooks so the guy in front of me could pull me up snowy hills with his IROK's.
In the pic below, I got stuck with the Xterrains. My buddy the 86 Ranger with BFG's made it through.
To sum it up.............
The XTerrains were the worst tires I have ever purchased. I don't like them & I feel I wasted my money on them. I say this because of running the same trails & the same obstacles with the XTerrains and other tires. The other tires always outperformed the Xterrains. My hatred for XTerrains is not based on hearing or reading stories about them...........it's based on actual experiences & events running the XTerrains & other tires.
I'm not trying to sway you away from them, I'm just giving my truthful input.
