Pinpoint Tests

Pinpoint Tests
For a description of the various tire wear patterns, refer to Inspection and Verification. Inspection and Verification

For vehicles with different front and rear tire pressure (such as E-Series and certain F-Series), the tire pressures must be adjusted and the tire pressure sensors must be trained following a tire rotation. Refer to Tire Pressure Monitoring System (TPMS) Sensor Training. Failure to train the sensors will result in a false low tire pressure event, which will cause the tire pressure monitoring system (TPMS) indicator to illuminate. Tire Pressure Monitoring System (TPMS) Sensor Training

For vehicles with the same tire pressure for front and rear tires, tire rotation will not affect the TPMS.
