Why do you think that this setup is crazy!!! First, I check out a thread that was posted by Dex on 02/28/02. I believe subject was "What's the widest tire you could put on stock 17" wheels". He used the same setup (235/45-17Front - 265/40-17Rears) . Second, I spoke to a rep at Tire Rack, He said that this combination should workout just fine. I am still open to your comments/ suggestion on this subject. Please share.
