304 STARTING AND OPERATING WARNING! • Do not use a tire, wheel size or rating other than that specified for your vehicle. Some combinations of unapproved tires and wheels may change suspension dimensions and performance characteristics, resulting in changes to steering, handling, and braking of your vehicle. This can cause unpredictable handling and stress to steering and suspension components. You could lose control and have an accident resulting in serious injury or death. Use only the tire and wheel sizes with load ratings approved for your vehicle. • Never use a tire with a smaller load index or capacity, other than what was originally equipped on your vehicle. Using a tire with a smaller load index could result in tire overloading and failure. You could lose control and have an accident. (Continued) WARNING! (Continued) • Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire failure and loss of vehicle control. CAUTION! Replacing original tires with tires of a different size may result in false speedometer and odometer readings. TIRE CHAINS Use only compact chains or other traction aids that meet SAE type "Class S" specifications. Chains must be the proper size for the vehicle, as recommended by the chain manufacturer. In addition, only install tire chains on P215/65 R17, P225/60 R18, and P235/55 R18 size tires. The 245/45 R20 size tires do not provide adequate clearance for tire chains.
