I have been looking for an answer to this seemingly easy question but so far I haven't been able to find it.
Two weeks ago I brought home a new 2009 CTS with 17" wheels and I can't stand them! I want to get new wheels and maybe new tires as well - I haven't made up my mind yet.
Assuming I keep the current tires, what is the bolt pattern and offset of the stock wheels? The tires are P235 55R17.
Thanks for your help!
