Running 15X10 Draglites with 6.5 B/S. Have Hoosier Quick Time Pro's 28X13.5X15. Fit with no quads, tailpipes rubbed, so i dumped the exhaust before the rear axle. I recommend getting a torch and a BFH (Big Flippin' Hammer) and get ready to heat and beat. After that, spraypaint the inner wheel wells and take it for a ride...if the paint smudges you have rubbing. I'd say on a 10" wheel you could go as big as 315's no problem using this method. The prefered rim is a 15X8 with 5.5 backspacing...that will let you keep your quads and no modification to your wheel wells. Any questions..ask away. Good Luck!
