498 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 a collision 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 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 a collision. (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 (TRACTION DEVICES) Use of traction devices require sufficient tire-to-body clearance. Follow these recommendations to guard against damage. • Install on Rear Tires Only
