Looking at the Weld Pro Stars, seen a lot of pics with 15x8 4.5 backspacing and tires like 255/60's...just wondering if theres room on the inside to do 5.5 backspacing so they go in the well a little better, than a 275/50 or 60 tire. Cars lowered an inch, so im afraid it will hit the outer fender. If so, any pics?

My formula has a 15x8 with a 4 1/2 inch backspacing and 275 50 R15 tires.I lowered it a 1.5 in the back this passed weekend because it sat up a little to much.I know you can run a 5 1/2 inch backspacing but do not know if a tire of my size will fit without rubbing on the inside of the wheel well.
