Im am buying a 07 STS in a couple of months.. but i have a question. When i look at wheels for the car it shows that the biggest size wheels that i can put on the car on 20's. But yet i have seen pics with the 07 with 22"s . So seeing that 22's fit do I have to clear my fender space or should they just fit?
Thank you to anyone that can ansewer my question.
