Rotation, pressure adjustment and TPMS reset example
The following example describes all the major steps involved in rotating
tires on a vehicle with different front and rear tire pressures. It
illustrates that the TPMS reset procedure needs to follow tire rotation
and pressure adjustment to avoid a possible false low tire warning.
Example:
A particular vehicle has the following recommended tire pressures: 50 psi
(345 kPa) front; 80 psi (552 kPa) rear.
Note: For your vehicle’s pressure, refer to the Safety Compliance
Certification Label located on the B-Pillar or the edge of your vehicle’s
driver’s door.
Before tire rotation
Sensor 1: 50 psi
Sensor 2: 50 psi
Sensor 3: 80 psi
