Tires, Wheels and Loading information placard (label). Driving on a significantly under-inflated tire causes the tire to overheat and can eventually lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Even if your vehicle is equipped with a Tire Pressure Monitoring System, it is still important that you manually check the inflation pressure of your tires regularly. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure which can be found on either the Safety Compliance Certification Label which is located on the B-Pillar or the edge of the driver's door. The Tire Pressure Monitoring System is NOT a substitute for manually checking tire pressure. The tire pressure should be checked periodically (at least monthly) using a tire gauge, see Inspecting and inflating your tires in this chapter. Failure to properly maintain your tire pressure could increase the risk of tire failure, loss of control, vehicle rollover and personal injury. Changing tires with TPMS It is recommended that you always have your tires serviced by a dealer or qualified technician. Each road tire is equipped with a tire pressure sensor mounted on the wheel inside the tire connected to the valve stem. The tire pressure sensor must be unbolted from the wheel prior to tire removal. The sensor can be removed by loosening the nut at the valve stem. Failure to remove the sensor may damage it. The rubber grommet (washer) between the wheel and the tire pressure sensor needs to be replaced whenever the sensor is removed to minimize air leaks. The tire pressure should be checked periodically (at least monthly) using an accurate tire gauge, refer to Inspecting and inflating your tires in this chapter.
