Ultra High Performance Summer Tires This vehicle may come with 285/ 35ZR20 and 305/35ZR20 ultra high performance summer tires. These tires have a special tread and compound that are optimized for maximum dry and wet road performance. This special tread and compound will have decreased performance in cold climates, and on ice and snow. Driving a vehicle with ultra high performance summer tires when temperatures are below approximately 5°C (40°F) is not recommended. If driving in these conditions, winter tires should be installed. See Winter Tires on page 10-49.

Always store ultra high performance summer tires indoors and at temperatures above -7°C (20°F) when not in use. If the tires have been subjected to -7°C (20°F) or less, let them warm up in a heated space to at least 5°C (40°F) for 24 hours or more before being installed or driving a vehicle on which they are installed. Do not apply heat or blow heated air directly on the tires. Always inspect tires before use. See Tire Inspection on page 10-62.
