So, I bought a 2014 CTS Vsport Premium just before Christmas, and am now dealing with the realities of winter in Chicago. The brochures and Cadillac website clearly state that the Vsport comes with "summer only" Pirelli run-flat tires, but i am having a helluva time finding winter tires/wheels as replacements. Specifically, I'd like to get 4 replacement tires (preferably Bridgestone Blizzak), mounted on aftermarket rims, so that I can run them through the winter and then switch back to the OEM rims/tires; but no one - including Cadillac - seems to have a clue as to what the wheel bolt pattern should be for the replacement rims. If anyone has any thoughts, I'd love to hear them. I am reluctant to pay $500 per wheel for Cadillac rims (even if they were available) that I will only use 3 months of the year. For the record, this is all the info I can find:
Front Wheels: 18" x 8.5" 245v40r18
Rear Wheels: 18" x 9.5" 275v35r18
Help?
Front Wheels: 18" x 8.5" 245v40r18
Rear Wheels: 18" x 9.5" 275v35r18
Help?
