    ***Need help from the Pro's on how big of a tire I can fit on my stock 2004CTS-V***

    I have bought a 2004 CTS-V with 4 brand new 245/45/18. since you guys know what the heck your doing and the guy down at***Big-O*** says, yeah you could get away with a 255/40 on there... BS I know you guys will head me in the right direction. I was thinkin at least a 285 if not 295. its a daily driver unless someone acts a fool at a light or on the road or anywhere... Thx guys, best forum I have ever been a part off...

    275/40 on the rear. It'll run with anything too much wider and that's already stretching it on a
    8.5" wheel. You can widen the wheel and get offset trailing arms to fit up to a 295. 275/40 is the same diameter as stock so your speedo will still be correct and you won't run into any stabilitrac issues.

    Stay with stock size up front. 255's will fit but not worth the different sidewall height.

    This has been discussed a billion times. Everyone is going to tell you to do a search. Above is the general consensus, you can search if you want more info.

    Thank you, and yes I do want new wheels and the right stagger. The guy I bought it from put a little taller tire on for ride quality. I'm sure I can find out somewhere but what were the stock tire size on the CTS-V? I appreciate the quick responce and your know how.. THX

    I searched, thanks again..

    I put 275-40-18 Run flats on all 4 corners of my 07 DD. The front rubs a little on full lock and the edge of the upper a-arm needed to be clearanced (?) a little. No complaints but mine is stock height.
