Maintenance and Specifications Tires that are larger or smaller than your vehicle's original tires may also affect the accuracy of your speedometer. SNOW TIRES AND CHAINS Snow tires must be the same size and grade as the tires you currently have on your vehicle. The tires on your vehicle have all weather treads to provide traction in rain and snow. However, in some climates, you may need to use snow tires or chains. Follow these guidelines when using snow tires and chains: • Use only SAE Class S chains with P225/55R16 tires. • Do not use tire chains with size P235/50R17 tires. Use of SAE Class S chains or other chain types may damage your vehicle. • Install chains securely, verifying that the chains do not touch any wiring, brake lines or fuel lines. • Drive cautiously. If you hear the chains rub or bang against your vehicle, stop and re-tighten the chains. If this does not work, remove the chains to prevent damage to your vehicle. • If possible, avoid fully loading your vehicle. • Remove the tire chains when they are no longer needed. Do not use tire chains on dry roads. • The suspension insulation and bumpers will help prevent vehicle damage. Do not remove these components from your vehicle when using snow tires or chains.
