16" mickey thompson wheels standard backspacing and 305/70 R16 Mickey Thompon Baja MTZ
which is a 33/12.5 R16
no rubbing in the rear. It rubs the shrockworks bumper just slightly on one side. I was jumping it in the desert and managed to catch a fender with the tire which crinkled it but in general very very little rubbing.
In fact my tracker with the Old man emu 2" lift/2" body lift/ hagan widening in the front and 31/11.5 R15 tires with 2.75 backspaced wheels rubbed more. waaaaaay more. It's a great kit and it works really well and I really am happy with it.
