  the passage

  Changing of tire size on mid-size and full-size trucks and utilities

Steps to confirm (in the document’s order)

1. A calibration exists for 20" or 22" wheels and tires on full-size trucks under the latest version of TSB 03-03-10-006 or 06-03-10-011.

   the passage

   Example: A second example would be the latest version of TSB 03-03-10-006 or 06-03-10-011 - which offers 20" or 22" wheels and tires for the full-size trucks.

2. A calibration is available only if a vehicle of the same model year, body style, engine size, transmission type, axle type and suspension type can be built in the sales order guide with that tire.

   the passage

   If you can build a vehicle, using the sales guide, using the same model year, body style, engine size, transmission type, axle type and suspension type, any tire offered for that combination will have a corresponding calibration available.

Repair

• Once the tire application is confirmed in the sales guide, contact the Techline Customer Support Center (TCSC) to determine calibration availability.

  the passage

  Once the tire application has been confirmed per the sales guide, contact TCSC to determine calibration availability.

Caution

• GM supports a tire calibration only for tires that have been sized, tested and designed for the vehicle and its applications.

  the passage

  General Motors will ONLY support a tire calibration for tires that have been sized, tested and designed for the vehicle in question and its applications.

• Do not use the tire size selection offered in the ABS module as a guide to which tires fit the vehicle.

  the passage

  DO NOT use the information offered in the ABS module (tire size selection) as a guide to see what tires are applicable to the vehicle in question.

• Changing the tire size in the ABS module affects only the wheel speed sensor calibration inside the ABS module; it does not correct the speedometer, and does not change the rear speed value on vehicles that take rear wheel speed from the ECM/PCM/VCM via the VSS.

  the passage

  Keep in mind, changing the tire size in the ABS module will on affect ABS wheel speed sensor calibration that are direct inputs to the ABS module. It will not correct or calibrate the speedometer's accuracy, and will not change the calibration of the ABS rear speed sensor value on vehicles that obtain rear wheel speed data from the ECM/PCM/VCM via the VSS.
