i believe i am running 3.5" backspacing on my 15x 8's with 31x10.5 tires. with the 4" rsg lift and the 1.5" body lift i still had to hammer out the fender and body seam just in front of the door. i also though am not running a front bumper cover, so i am not sure on if it would have rubbed there or not.

i am going to have to resort to a few mini truck lowrider tricks when i get my new tires on!
