Put a streight edge on the wheel drum and measure to the inside of the wheel well. Take off 1/2" for play and take off the measurement for the sidewall. Whats left is what the back spacing of the rim should be. From there you can figure how wide of a rim that will fit (with the tire)without rubbing the rear quarter panel. Its not rocket science, but you have to know the rim sizes available and the tire specs, and then its up to you and some measuring.

I have 17x8 on my rear with a 4.5'' basckspacing --i had the same on front however when i installed disc brakes i had to go with 17x8 with a 5 '' backspace
