Back to the wheels.... In the rear I have a 275/35/20 on there and seem to be fine. I removed the coil spring and bump stop and let it all the way down and the tire doesn't rub but it's close. Should be fine with the bump stop back in. The outer portion of the inner fenderwell has been modified and basically welded to the quarter panel and the rear end was narrowed. It's a mod I did twenty years ago to fit big slicks without cutting the frame. It's held up all these years so I guess it'll work for now
