Not sure if in correct forums but quick question. Im getting a 08 coupe but want to keep my current 18 tsw rims i have the stock 18 rims but no tires any one have experience as far as when u trade in what the dealer is looking at when u take the car to exchange. Im not trying to spend 600 on some tires that all im gonna do is get rid of thanks for any info in advance...

 

Why are there not still tires on the factory wheels? If they are the same tire size, then put the ones from the TSW 18"s on the factory wheels, and buy a new set for yourself.
