| Re: New Tires on Stock 17's The CTS-V has 245/45-18. The wheel wells are the same. So correct me if I am wrong, but I should think that size would work on the CTS as well. The only difference I see is that the wheels on my V are closer to flush with the fenders, where on the CTS, they are recessed a little. Assuming the studs are long enough, spacers should take care of that. Bear in mind though, you will likely loose performance and economy with a wider tire.
What I would like to do when I replace the tires on my CTS is stay with 225 width, but go with a larger profile. So instead of 225/50-17, go to the 225/55-17 or maybe even 225/60/17 to give me a little more cush over the crappy roads here in Chicago.
