For all you tire guru's:

Is it possible to get the tires' width to extend slightly beyond the cladding for a more rugged look? Does the size/width of the tire matter? I don't mean the late model Honda Civics with 10 inches of tire extending beyond the body, I hate that look SO MUCH!!
I just want 1-2 inches to stick out for a more "tank-like" look. I appreciate any replies!! Thanks!
