I'm sure this has been posted somewhere, but below is a pretty clear Michelin Customer Service reply about Sport summer tires.

We are happy to hear that you are interested in our tires. Michelin Ultra-High Performance (UHP) Sport Summer tires use tread compounds that are optimized for maximum dry and damp grip in temperate conditions. As the temperature of the compound nears freezing, the grip level of the tire begins to degrade. Michelin does not recommend using UHP Sport Summer tires when tire temperatures drop below 40°F (5°C) or on snow and ice.

At tire temperatures below 20°F (-7°C) Michelin UHP Sport Summer tires may develop surface cracks in the upper sidewall and tread area if flexed. Do not use, roll, or drop MICHELIN UHP Sport Summer tires with temperatures below 20°F (-7°C). If the tires have been cooled to 20°F (-7°C) or less, let them warm up in a heated space to at least 40°F (5°C) before being installed or moving a vehicle on which they are installed. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use. Never use a tire with freeze cracks, breaks, or damage to the sidewall or tread.

We appreciate your business and thank you for choosing Michelin.

Interesting!

Strange! Michelin must have altered the SS compound. I drove my old c6zo6 in snow and cold weather and never had a single issue.
