Wheels and Tires USING SUMMER TIRES (If Equipped) 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 40ºF (5ºC) 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 20ºF (-7ºC). The rubber compounds used in these tires lose flexibility and may develop surface cracks in the tread area at temperatures below 20ºF (-7ºC). If the tires have been subjected to 20ºF (-7ºC) or less, warm them in a heated space to at least 40ºF (5ºC) for at least 24 hours before installing them on a vehicle, or moving the vehicle with the tires installed, or checking tire inflation. 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 the tires after storage periods and before use. WARNINGS Snow tires must be the same size, load index, speed rating as those originally provided by Ford. Use of any tire or wheel not recommended by Ford can affect the safety and performance of your vehicle, which could result in an increased risk of loss of vehicle control, vehicle rollover, personal injury and death. Additionally, the use of non-recommended tires and wheels could cause steering, suspension, axle, transfer case or power transfer unit failure. The tires on your vehicle may have all-weather treads to provide traction in rain and snow. However, in some climates, you may need to use snow tires and chains. Use chains on the tires only in an emergency or if the law requires them. Note: The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires and chains. Follow these guidelines when using snow tires and chains If possible, avoid fully loading your vehicle. Chains may damage aluminum wheels. Use ultra low profile cables, 10 mm or less in dimension as measured on the sidewall of your tire, with 235/55R 17, 235/50R18 and 255/40R19 on the rear axle only. Do not use snow chains or cables with 275/40R19 and 265/35R20 tires. Not all S-class snow chains or cables meet these restrictions. Chains of this size restriction will include a tensioning device. • • USING SNOW CHAINS WARNINGS Driving too fast for conditions creates the possibility of loss of vehicle control. Driving at very high speeds for extended periods of time may result in damage to vehicle components.c 256 Mustang (), enUSA, First Printing
