Perfect backspace

[Mitch]

Anyone have 15x7 rims that don't rub when turning 33 or 35" tires?

 

Same question for 15x8!

 

Thanks!

Generally, the diameter of the tire is not whats hurting you its the WIDTH!

 

The 12.5 " width tires are a problem on XJ/MJ's. The 10.5's make life and fitment MUCH easier!!!

 

Go with at least 4.5"BS but no less than 3.75" and a 15X7 rim and you should be fine. (15X8 will work as well but remember the BS is the same.) The wider rim will push the tire out and could become and issue with the sheetmetal upon compression. This is all provided you have proper lift for that DIAMETER tire. ;)

Thanks and yes, I will only be running a 9.5 or 10.5 wide tire.

And how is backspace measured?
