Does anyone know what the back spacing on 17x8 or 18x8 reverse wire wheels are? I want to put these on my 95 gmc sonoma 2 wheel drive. I know they will stick out, but how much? I plan on putting the 4x4 flares on the truck when i put the wheels on. I would rather not put the flares on but the cops around here would have a field day with me if i dont. Thanks in advance.
