INFORMATION
Subject:
GM Guidelines for Changing Tire and Wheel Assemblies
Models:
2008 and Prior GM Passenger Cars and Light Duty Trucks (including Saturn)
2008 and Prior HUMMER H2, H3
The purpose of this bulletin is to provide additional information and guidance when changing out tire and wheel assemblies on any General Motors vehicle. Given the market demand to personalize vehicles with different tire and wheel assemblies, it is important to remind dealers of the vehicle implications and requirements that are the responsibility of your dealership.
The National Traffic and Canadian Motor Vehicle Safety Act (Safety Act) provides, in part, a dealer may not sell vehicles or equipment that do not comply with the applicable safety standards. Dealers are prohibited from making inoperative, in whole or in part, any part of a device or element of design installed on or in a motor vehicle in compliance with an applicable motor vehicle safety standard. Accordingly, a dealer must replace the vehicle tire and loading placard if, after the dealer installs GM Accessory Wheels and Tires, the information required is no longer accurate.
As a reminder, GM Accessory Wheel and Tire Assemblies are released in approved tire and wheel combinations that have been designed and validated by GM Engineering for a specific vehicle application. Each GM Accessory wheel contains the appropriate installation instructions which may include, but not limited to, change to the TPMS (Tire Pressure Monitoring System), updating the ABS Module to reflect correct tire size, vehicle calibration and updating the tire size information using the Tire Placard insert (as shown in the example).
FMVSS and CMVSS 110, Tire Selection and Rims, requires the "Tire Placard Label Insert" (refer to graphic-English shown - French and Spanish included for accessory wheels) to be affixed to each vehicle.
Do not use the information offered in the ABS module (tire size selection) as a guide to determine what tires are applicable to the vehicle in question. Changing the tire size in the ABS module will only affect ABS wheel speed sensor calibrations that are direct inputs to the ABS module. It will not correct or calibrate the speedometer's accuracy or other sensor values. To verify if GM Accessories offers optional tire and wheel combinations for a specific vehicle configuration, refer to GM Dealer World - "Accessory Information Center". In Canada, refer to GMinfoNET - "Product Information - Accessories" located under Parts & Accessories page.
Installation of Non-GM Products:
Before non-GM products are installed on new vehicles, dealers should refer to Article 5.1.1 of the GM Dealer Sales and Service Agreement ("Dealer Agreement"). If a dealer modifies or sells a modified new vehicle, or installs any equipment, accessory, recycled part or part not supplied by General Motors, the dealer must disclose this fact on the purchase order and bill of sales, indicating that the modification, equipment, accessory or part is not warranted by General Motors. Refer to form "Dealer Disclosure of Non-GM Products Used" in section 3.3 (3.2.1 in Canada) of the GM Service Policy and Procedures Manual.
Vehicle Repairs:
Refer to Article 7.2 of the Dealer Agreement - The dealer agreement provides that dealers will only use genuine GM or GM approved Parts and Accessories in performing warranty repairs, special policy repairs and any other repairs paid for by General Motors. This also is addressed in Article 1.2.4e of the GM Service Policy and Procedures Manual.
