GM bulletin #13-03-10-001A: "Information on Tire Cold Weather Cracking" – (Jan 30, 2014) advises “avoid driving, moving, or test-driving vehicles equipped with high-performance summer-only tires below 20º F as operating at these temperatures can cause damage to the tires.” The car models affected include the 2012-2014 Buick Regal GS, 2014 Cadillac CTS Vsport, 2012-2014 Chevrolet Camaro ZL1 and Z/28, 2014-2014 Chevrolet Camaro SS 1LE, and the 2014 Chevrolet Corvette Stingray and Stingray Z51, and SS sedan.
In GM’s quest to deliver the ultimate handling in these cars, they built performance tires with essentially a racing compound to deliver the goods. These tires are great for driving in temperate areas and are ideally suited for track use, but the practicality of the tires stops there.
Reaching out to a GM tire supplier, Pirelli, a spokesman explained that the performance tread compound becomes so stiff on such tires that it can lead to cracking when deformed in cold weather.
