Wheels and Tires: Service Precautions

Precautions in Wheels and Tires Servicing
- Wheel repairs that use welding, heating, or peeling are not approved. All damaged wheels should be replaced.
- There are two types of vehicles, whether equipped with TPMS or not. Check which type of vehicle is being serviced, referring to Identification of Vehicle with TPMS first before servicing its tire or wheel. Failure to follow the specified procedure when servicing the tire or wheel of the TPMS equipped vehicle may cause damage to the tire pressure sensor.

TPMS
- As the wheel of the TPMS equipped vehicle has a tire pressure sensor, its differs in the shape from that of the vehicle without TPMS. When replacing the wheel of the TPMS equipped vehicle, be sure to use the genuine wheel specified by the manufacturer.
- When replacing the tire of the TPMS equipped vehicle, check to make sure that the tire size is as specified in the "Tire Placard". If the size of the installed tire is out of specification, the tire pressure sensor may be broken because of its contact of the bead of the tire.
- When repairing the flat tire, do not use the liquid sealants for the flat tire. There is a roll switch built in the tire pressure sensor which is installed to the wheel. If the liquid sealants for a flat tire is used, it may cause this roll switch to be stuck and fail to function properly.
- For precautions to be taken when diagnosing troubles of the TPMS equipped vehicle, refer to Precautions in Diagnosing Troubles.

Studs
If a broken stud is found, replace it.
