And yeh the side wall won't stretch but near the wheel lip it will..If you run wide ass tires on skinny wheels the tread will balloon up some too wearing the middle of the tires down quicker unless you air down a shit load. The width of the tires just isn't noticeable going from 1" wider or narrower wheel bc its changes so slightly..I'm pretty sure a 12.50 will be wider on a 14" wheel than on a 7" wheel. But haven't done it lol
Wider wheels can't stretch/bulge sidewalls?? hmmm haha
^^ This guy should not be allowed to own a truck! That is absolutely retarded. Stretched tires look bad enough on lowered cars. They have absolutely no place on lifted trucks.
And yes Jake09, you are completely right.
