Mike I originally built my rear end around the M/T ET Streets that are 28" X 12.5. They actual bulge to 13" when I measured them on my Radir 10"rims. The BFG Drag Radials were 325 60/15 and were wider. I played with spacers moving the rims around and they would still hit on the inside even with a sway bar and more than one person in the car. The outside I could get my fingers in the inside i had maybe 5/8 clearance. I recently bought new MT Drag radials 295/55/15 28"X 12 they bulge on my rim to 12.25 and never hit. If you have a higher ride height you may be able to use the 325/50/15 tires. I don't have any pictures to show the clearance of the old tires. Jayson
