Summer tires provide superior performance on wet and dry roads. Summer tires do not have the Mud and Snow (M+S or M/S) tire traction rating on the tire side wall. Since summer tires do not have the same traction performance as All-season or Snow tires, we do not recommend using summer tires when temperatures drop to about 45 °F (7 °C) or below, depending on tire wear and environmental conditions, or in snow and ice conditions. Like any tire, summer tire performance is affected by tire wear and environmental conditions. If you must drive in those conditions, we recommend using Mud and Snow (M+S, M/S), All-season or Snow tires.
Always store your summer tires indoors at temperatures above 19 °F (-7 °C). The rubber compounds used in these tires lose flexibility and may develop surface cracks in the tread area at temperatures below 19 °F (-7 °C). If the tires have been subjected to 19 °F (-7 °C) or less, warm them in a heated space to at least 41 °F (5 °C) for at least 24 hours before installing them on a vehicle, or moving the vehicle with the tires installed, or checking tire inflation. Always inspect the tires after storage periods and before use.
