I have 33x12.5 Pro Comp M/T's and am thinking of going to KO's in the same size to get a better all around tire since winter is around the corner. My question is has anyone wheeled them on rocks/mud and how did they perform/hold up?? Are the sidewalls decent?

 

Had them on my TJ, did great in more arid wheeling in Arizona, Colorado, and Moab. They don't have a good reputation in mud. I never had any sidewall issues, but they aren't a hardcore M/T so I wouldn't expect the same level of durability off-road, still pretty impressive though. The good thing is that in the snow, and especially ice on-road, they are outstanding. They also offer phenominal tread life.

 

i got the exact same seize on my mazda b-4000 , in mud you got to rev it a little bit to clean the treads , in snow they are outstanding and the are vertually "unwearable" you can easily ride them for more than 100000mi


but they are not cheap , this winter i will try the procomp AT they are a lot cheaper , i got a set of 5 for the price of 4 KO
