Off roading wouldn't cause a problem with re-treads, the only thing that re-treads really have a problem with is highspeed-longdistance highway miles, and having alot of weight on them. Thats why 18 wheelers have soo many blowouts, they are dooing both the things that those tires don't like.wycowboy said:. I wouldn't use them for any serious off roading though.
