I have an X with staggered wheels, just 8.0 and 8.5 in the back. If i run same tires all around. How weird would it be to have the 8.5 in the front, other then the odd looks would there any issues?

Yea i know obviously you want the larger wheels on the primary drive wheels which are the rears. But finding another set of wheels local to me isn't that easy. I dont see how drive train damage can occur, other then the slight difference in weight of the wheels. The aerodynamics and traction properties might be off.
