Thanks to Ultimate 4 Wheel Drive Performance , I'm riding around on 36" IROK's as of last night. Here is a comparison of a 35" Wild Country TXR, a 36" IROK, and a very worn 35" BFG M/T (with my helper in the background) Backyard testing (yes, they rub with 4" of lift and cutouts) They are very soft tires. I can't wait to try them out on the trail. By design they seem like they'll do great in both mud and rocks, but wear very fast on the street. I suppose that just means I'll have to wheel as much as possible!
