Inspect the vehicle's tires and make sure they are inflated to the correct pressures. Do not forget to check the spare tire, if the vehicle has one. See Inflation - Tire Pressure. If the vehicle has a spare tire, check to make sure it is stored securely. See Changing a Flat Tire.

Tire rotation may be required for high mileage highway drivers prior to the Engine Oil Life System service notification. Check the tires for wear and, if necessary, rotate the tires. See Tire Inspection and Rotation .
