While this bulletin is specific to C7s and newer Cadillac models, it is a warning for those of us that have replaced the old PS2 tires with the new Pilot Super Sport tires - like me. Both my Vette and my CTS V have Super Sport tires now.
Generally, neither of them come out of the garage when the temps are below 40 but....
The last thing I want to do is buy a second set of wheels and winter tires for either. And, who makes a winter tire in C7 ZO6 sizes like my 427 uses?
Another reason to drive the ATS with all-wheel drive in the winter instead of the Vette or V.
