This bulletin is being revised to add the 2011 model year. Please discard Corporate Bulletin Number 06-03-10-012C (Section 03 - Suspension).
The purpose of this bulletin is to provide a reference guide for the technician to upgrade a vehicle from factory wheels and tires to 19" wheels and tires, which are available through GM Accessories. This guide will cover tires, wheels, vehicle modifications, and warranty information.
Vehicle Modifications
Tire Label
Important
Vehicles originally equipped with 19" tires (RPO QCW or QUP) DO NOT need a new label.
After installing the recommended P255/60R19 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 jamb. To locate the label within the red box use the upper 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°C (65°F). The label is provided as a guide for tire inflation pressures and information relevant to occupant/cargo capacities.
Tire Pressure Monitor (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).
TPM Sensor Relearn Procedure
1. Turn ON the ignition, with the engine OFF.
2. Apply the parking brake.
3. Using the DIC, press the vehicle information button until the RELEARN TIRE POSITIONS message displays. If your vehicle does not have the DIC buttons, press the trip odometer reset stem located on the instrument panel cluster until the RELEARN TIRE POSITIONS message displays. If your vehicle has the DIC buttons, press the set/reset button. The horn will sound twice to indicate the TPMs receiver is ready, and the TIRE LEARNING ACTIVE message will display. If your vehicle does not have the DIC buttons, press and hold the trip odometer reset stem until the horn chirps twice and the TIRE LEARNING ACTIVE message is displayed.
Alternate method: Simultaneously press the keyless entry transmitters lock and unlock buttons until a horn chirp sounds or use the Tech 2(R) to initiate the learn process. A horn chirp will sound indication the mode has been enabled.
4. Starting with the left front tire, hold the antenna of the J 46079 against the tire sidewall close to the wheel rim at the valve stem location then press and release the activate button and wait for a horn chirp, or increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before the 8-10 second pressure increase/decrease time period has been reached, or up to 30 seconds after the 8-10 second pressure increase/decrease time period has been reached.
5. After the horn chirp has sounded, proceed as in step 4 for the next 3 sensors in the following order:
- Right front
- Right rear
- Left rear
6. After the LR sensor has been learned, turn OFF the ignition to exit the learn mode.
7. After the learn mode has been exited, adjust all tire pressures to the recommended PSI.
Electronic Brake Control Module (EBCM) Reprogramming
EBCM reprogramming is only required on vehicles when upsizing from 18" tires/wheels to 19" tires/wheels. Contact Techline (1-800-828-6860 English or 1-800-503-3222 French) to obtain a VCI number. Record this number on the form below. Use the Service Programming System (SPS).
For proper vehicle operation and to ensure coverage under the provisions of the new vehicle warranty, the vehicle must be reprogrammed with the correct calibrations as soon as the accessory wheels are installed.
Important
Module reprogramming must be done using Pass-Thru method.
1. With the Tech 2(R) still connected, select the proper reprogramming method: "Pass-Thru" and "Reprogram ECU", then "Next.".
2. Build the vehicle.
3. Verify that the VIN is correct, then "Next."
4. Select the proper controller to be programmed: "EBCM Electronic Brake Control Module."
5. Select the proper programming mode: "VCI" , then "Next."
6. On the following screen, select the proper calibration "Electronic Brake."
7. Enter the VCI number obtained when calling TCSC, then "Next."
8. From the part numbers displayed, select the one containing the correct wheel size in its description, "Next."
9. On the following screen, select "Done."
Checking and Clearing DTCs After Reprogramming
DTCs codes may be set as a result of the programming process. In most cases the codes can be cleared using the Tech 2(R) and following the procedure listed below.
1. Install the Tech 2(R) to the vehicle.
2. Turn the ignition ON with engine OFF.
3. Enter "Diagnostics" and build vehicle according to model year, vehicle line, etc.
4. Select "Vehicle Control Systems."
5. Select correct engine.
6. Select "Vehicle DTC Information."
7. Select "DTC Display." Scan tool will check all modules for any DTCs that are set.
8. Select "View all DTCs."
9. Select "Clear DTCs."
10. Press the "exit" key to escape.
Important
If original equipment tires/wheels are reinstalled, it will be necessary to reset the programming of the PCM to the original specifications.
Front Stabilizer Shaft Replacement
Installing the larger (32 mm) diameter front stabilizer shaft is required only when upsizing from 18" tires/wheels to 19" tires/wheels on the Acadia and OUTLOOK AWD configurations. This will be installed for vehicle handling purposes. Replace the front stabilizer shaft with GM•P/N•19166517, using the procedure listed below.
Notice
Secure the steering wheel utilizing a strap to prevent rotation. Locking of the steering column will prevent damage and a possible malfunction of the SIR system. The steering wheel must be secured in position before disconnecting the following components:
- The steering column
- The intermediate shaft
- The steering gear
After disconnecting these components, do not turn (steer) the front tires/wheels/knuckles. Failure to follow these procedures may cause improper alignment of some components during installation and result in possible damage to the SIR coil.
1. Raise and support the vehicle.
2. Remove the front tires and wheels.
3. Reposition the intermediate shaft boot and remove the bolt (1) attaching the intermediate shaft to the steering gear.

Important
For GM Accessories installed on a vehicle at Point of Sale (added by the dealership) or after the customer has taken delivery, it is important to add the appropriate RPO/LPO code to the vehicle with via a ZSET (Service Event Transaction) in the Global Warranty Management (GWM) System. By submitting a ZSET, the dealership is providing the customer with proof that a Genuine GM Accessory was installed through a GM Dealership. Upon submission of this ZSET transaction, the appropriate RPO/LPO code will be added to the VIN in the GWM System on the IVH (Investigate Vehicle History) screen.
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 Bumper to Bumper Limited 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).

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.
