Okay, now I don't understand what you're trying to do. What size tires are you trying to mount on each of these 8.5" wide wheels? Are you saying you only bought one pair of wheels, so you'll have 20-inch wheels in the front and 18-inchers in the rear?

They look like a square set from a lt1. Same size as on my 21 rs v6. 20-8.5 with 25mm offset. The 18-8.5 that came on his car have a 32 mm offset . The 20" wheels will stick out 7 mm more giving 7mm more Clarence on inside and a more aggressive look.
