    Attention:* *Advise customers of these vehicles that they are equipped with a high performance summer-only tire that will have reduced traction performance at temperatures below approximately 40F (5C). GM recommends installing winter tires if driving below these temperatures. Avoid driving, moving, or test-driving*vehicles equipped with high performance summer-only tires below 20F (−7C), as operating at these temperatures can cause damage to the tires. This Bulletin also applies to any of the above models that may be Export vehicles.



    This Bulletin has been revised to update the Model Years. Please discard Corporate Bulletin Number 13-03-10-001C.



    Cold Weather Operation

    The vehicles referenced above are all equipped with 3 season performance tires commonly referred to as Summer Tires.

    The rubber used in these tires loses flexibility and may develop surface cracks (1) in the tire tread/shoulder area at colder temperatures. Refer to the photos below for examples.

    Surface cracks are cosmetic and will not result in a loss of air, however special tread and compounds used on these performance tires will cause a decrease in performance in cold climates. Driving with high performance summer tires on snow, ice or cold road surfaces may cause loss of control.


    Important: While the cracking will not result in air loss, it is damaging to the tire. Tires that have been used in cold climates and exhibit tread cracks should be discarded.

Inflate the tires only after they have been warmed above 5C (40F). Do not place tires near heaters or heating devices used to warm the room where the tires are stored. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use after being stored.
