Attention:

Supercede:
This bulletin is being revised to add the 2011 model year and update information. Please discard Corporate Bulletin Number 07-03-10-010B
(Section 03 - Suspension).
The purpose of this bulletin is to provide a reference guide for the technician to upgrade a vehicle to 18" wheels and tires, which are available
through GM Accessories. This guide will cover tires, wheels, vehicle modifications and warranty information.
Tires
GM offers one tire, the Michelin PilotHX MXM4 P235/50R18 AL3 97V, P/N 19163349, to be used in conjunction with the 18" accessory wheels.
The Michelin PilotHX tire has a Tire Performance Criteria (TPC) spec of #1321MS, which meets or exceeds all federal safety guidelines.
Tire Pressure Monitoring (TPM) System
To avoid system malfunctions, it is necessary to install tire pressure sensors in the accessory wheels. Replacement sensors can be obtained or
sensors from the OE wheels can be transferred to the accessory wheels. After the wheels are installed on the vehicle, it is necessary to learn the new
sensor identification codes/locations into the remote control door lock receiver (RCDLR). Please refer to the proper relearn procedure.
Wheels
Center Cap
Notice
Attempting to "hammer on" the caps may result in damage to the cap.
Install the center cap onto the wheel after the tire has been mounted and balanced, but BEFORE the assembly is installed onto the vehicle. The
preferred method for center cap installation is by hand. As an alternate, use a non-metallic object to push the center cap into place.
Care/Cleaning
Use soap, hot water and a 100% cotton cloth to clean and polish the new wheels. Avoid car washes that use carbide tipped brushes, as these may
damage the wheel's finish. Periodically clean the backside of the wheel to remove road grime, brake dust and grease.
Mounting and Balancing
Refer to the most recent version of Corporate Bulletin Number 08-03-10-004A for proper methods for mounting, balancing and installing accessory
wheels and tires.
The mounted and balanced wheel/tire assemblies MUST meet GM service guidelines for measured radial force variation to ensure vibration free
performance.
The following radial force variation numbers for the assembly should be used as a guide:
If any wheel/tire assembly does not meet the above standards, refer to Corporate Bulletin Number 00-03-10-006F: Information on Tire Radial
Force Variation (RFV) for further information on possible corrective actions.
Vehicle Modifications
Tire Label
After installing the recommended tires, place the provided tire label on the vehicle. The new tire label should be located within the red box, over the
top of the original tire label found on the door jam. To locate the label within the red box, use the upper and left hand edge of the red line as a
guide. When properly placed, the new tire label will obscure the original tire information. Be sure that the surface is clean and dry. The surface
temperature should not be less than 21掳C (65掳F). The label is provided as a guide for tire inflation pressures.
Warranty Information

under the provisions of the New Vehicle Limited Warranty.
For the U.S., in the event GM Accessories are installed AFTER new vehicle delivery, or are replaced under the new vehicle warranty, they will be
covered (parts and labor) for the balance of the vehicle warranty, but in no event less than 12 months/12,000 miles. This coverage is only effective
for GM Accessories permanently installed by a GM dealer or a GM approved ADI (Accessory Distributor / Installer).
For Canada, in the event GM Accessories are installed AFTER new vehicle delivery, they will be covered (parts and labor) for the balance of the
vehicle warranty, or up to 12 months/unlimited kilometers depending on month installed. For replacement after the new vehicle warranty expires,
but within the 12 months/unlimited kilometers coverage, refer to claim type ZPTI guidelines.
GM Accessories sold over-the-counter, or those not requiring installation, will continue to receive the standard GM Dealer Parts Warranty of 12
months from the date of purchase (parts only).
Tires
Any approved tire installed on a GM Vehicle PRIOR to delivery will be covered under the provisions of the New Vehicle Limited Warranty. Tires
are covered against defects in material and workmanship. Tires are warranted for defects "without" prorated charge for tread mileage. Subsequent
replacements under this warranty will continue to be covered for the remainder of the New Vehicle Limited Warranty.
Any approved tire installed on a GM Vehicle PRIOR to delivery may continue to be warranted on a prorated basis by the tire manufacturer once the
New Vehicle Limited Warranty expires.
Any approved tire installed AFTER delivery will be covered under the provisions of the tire manufacturer warranty.
