Warnings:

• Do not exceed 30 mph (50 km/h).
• Do not use snow chains on snow-free roads.
• Only fit snow chains to specified tires.
• Remove wheel trims before fitting snow chains.
• If installing snow tires, all four must match original size, construction, and load range.
• Wheels and tires must match original size, load index, and speed rating.

Only use snow chains on rear wheels in pairs. Use SAE Class S chains (15mm or less) on specified tires:

• 265/70R17
• 275/65R18

Steel wheels are recommended when using snow chains. Guidelines:

• Avoid fully loading the vehicle.
• Purchase snow chains labeled for correct tire size.
• Do not exceed 30 mph or chain manufacturer’s limit.
• Stop and tighten chains if you hear rubbing; remove if needed.
• Remove chains when not needed or on dry roads.
• Do not use chains on a temporary spare wheel.
• Use chains that fit the tire sidewall to avoid rim contact.

Contact your authorized dealer for questions regarding snow chains.

Proper tire inflation is essential for safe operation. Check tires daily before driving and inspect pressures at least monthly or before long trips. Inflate to recommended pressures (see Inflating the Tires, page 447).

Inflating the Tires

• Under-inflation is a common cause of tire failure and can lead to accidents.
• Do not use the information display as a tire gauge.
• Use recommended cold inflation pressures for optimum performance and wear.
• Adjust hot tire pressures by adding 4 psi (27.6 kPa) over recommended cold pressure if measured after driving.

Inspecting the Tire for Wear

Replace tires when tread reaches 2/32 inch (1.6 mm) or wear bars are visible. Periodically check for uneven wear and remove debris.

Inspecting the Tire for Damage

• Check sidewalls for cuts, cracks, bruises, or bulges.
• Have suspected internal damage inspected professionally.
• Damaged or excessively worn tires should not be used.

Safety Practices

• Do not rapidly spin tires when stuck; can cause explosion.
• Do not spin wheels over 34 mph (55 km/h).
• High-speed driving increases hazard risk and tire damage potential.
• Replace damaged tires with the spare and visit an authorized retailer.
• Do not overload tires; follow gross axle weight and vehicle load limits.

Tire Alterations and Repairs

• Do not alter tires; alterations can void warranty and cause accidents.
• Have punctured tires inspected and repaired following USTMA recommendations.
• Plug-only repairs are not recommended.

Storage

• Store tires in a cool, dry, indoor environment.
• Remove weight from tires if stored more than a month.
• Avoid heat, ozone, grease, gasoline, and other damaging substances.
