TIRE INSPECTION AND ROTATION
Tire rotation is not recommended if your vehicle has the following performance tire combinations:
^
P235/50R17 size tires on the front wheels and P255/45R17 size tires on the rear wheels.
^
P235/50R18 size tires on the front wheels and P255/45R18 size tires on the rear wheels.
Different tire sizes front to rear should not be rotated. Each tire and wheel should be used only in the position it is in.
Tire rotation is recommended if your vehicle is equipped with P235/50R17 size tires on all four wheel positions or 255/45ZR18 size tires on all four
wheel positions. These tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km)
Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels.
The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Scheduled
Maintenance.
^
When rotating P235/50R17 or 255/45ZR18 size tires, always use the correct rotation pattern shown here.
^
Do not include the compact spare tire in your tire rotation.
^
After the tires have been rotated, adjust the front and rear inflation pressures.
^
Vehicles equipped with the Tire Pressure Monitor (TPM) system will need to have the sensors reset after a tire rotation.
^
Make certain that all wheel nuts are properly tightened.
CAUTION: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could
come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or
dirt off. See Changing a Flat Tire.
