Good on road, suck offroad. At least on this coast. I've never run the sticky versions, but I've seen them work well in rocks. You would be better off running a bfg-type mud terrain.
I ran them before (33's). They worked pretty well on rocks, but caked up badly in mud. On the street they weren't too bad. For a DD tire/mild wheeler I'd run them again.
I have been pleasantly surprised with how well mine have done. They wear well on the road, and if you can spin them, they will clean out. On rock, they flex well and the sidewalls are strong, for a radial.
I ran them for a a year or two. They wear really well on the street, and really don't do bad offroad for a radial. That being said, I think I would only run them again if I spent more time on the road than on the trail
i run the 37 inch stickys and like them alot. i just finished a rig for a customer/ friend and put pit bull rockers on it. after two trips they seem to be real good too.
