I have a set of m/t 275/50/r15 drag radials on stock gn wheels they rub alil one the frame (driver side)when backing out drive way.I am in need of new ones after 6,000 street miles(okay a few burnouts to).I am looking to put another set on but don't want to deal with them hitting frame again.So what in a m/t is same height but will not hit frame?I think i need like a 60 series instead of a 50...
