Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about the tire warranty and where to obtain service, see the vehicle warranty booklet for details. For additional information refer to the tire manufacturer.
WARNING:
Poorly maintained and improperly used tires
are dangerous.
- Overloading your vehicle's tires can cause overheating as a result of too much flexing. You could have an air-out and a serious accident. See Loading the Vehicle.
- Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury.
Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your vehicle's tires are cold. See Inflation - Tire Pressure.
- Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact—such as when you hit a pothole.
Keep tires at the recommended pressure.
- Worn, old tires can cause accidents.
If the tire's tread is badly worn, or if your vehicle's tires have been damaged, replace them.
Low-Profile Performance Tire
If the vehicle has 225/40R18 size tires, they are classified as low-profile performance tires.
These tires are designed for very responsive driving on wet or dry pavement. You may also notice more road noise with low-profile performance tires and that they tend to wear faster.
The 225/40R18 tire is a high performance tire designed for dry traction and handling performance which may result in reduced tread life of 15,000 miles (24 140 km) or less depending on individual driving behavior.
Notice: If the vehicle has low-profile tires, they are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like, potholes, or sharp edged objects, or when sliding into a curb. The vehicle warranty does not cover this type of damage.
Keep tires set to the correct inflation pressure and, when possible avoid contact with curbs, potholes, and other road hazards.
