My friend gave me a set of wheels, don't know what they are, but he had them lying around. They have some rust on them so i was going to sandblast them and paint them black. There a 5 bolt pattern, 15inch wheel. How do i find out if they will fit my truck or jeep (87 YJ). I know ours is a 5x4.5 bolt pattern, should that be printed on the wheel somewhere, as well as the backspacing? Is there anyway to measure that if it isnt. I haven't been able to check them out yet.
