Subject: Info - 20 Inch Accessory Wheels Available Through GM Accessories #06-03-10-011 - (09/25/2006)
Models: 2007 Chevrolet Silverado 1500 Series (? Ton Only)
2007 GMC Sierra 1500 Series (? Ton Only), Sierra Denali
--------------------------------------------------------------------------------
The purpose of this bulletin is to provide a reference guide for the technician to upgrade a vehicle from factory wheels and tires to 20" wheels and tires, which are available through GM Accessories. This guide will cover tires, wheels vehicle modifications, and warranty information.
Important:
20" accessories wheels released for 2007 model year (new style) full-size pick-ups are NOT compatible/interchangeable with 2007 and prior model year (classic) full-size trucks and utilities and vice versa. GM accessories wheels are validated and released for specific vehicle applications. In this case, a difference in wheel offsets exists between the different model years. Warranty coverage and dealer indemnification will not be provided in situations relating to incorrect application usage.
These wheels are compatible with 2007 model year full size utilities.
Tires
GM offers two tires; the Bridgestone Dueler H/L Alenza P275/55R20 or the Goodyear Eagle LS2 P275/55R20, to be used in conjunction with the 20" accessory wheels. The Bridgestone Dueler and Goodyear Eagle tires have a Tire Performance Criteria (TPC) spec of 1245MS (molded on the sidewall), which meets or exceeds all Federal Safety guidelines.
Tire Changers
Dealers must have the correct level of tire changing equipment to perform tire changing services. GM requirements and recommendations for servicing glamour wheels are as follows:
? ?? ?Rim Clamp design
? ?? ?Runflat capable (preferred)
? ?? ?Side mounted bead breaking to reduce stress on the wheel and tire
? ?? ?No metal contact to the wheel at the clamping jaws
? ?? ?Protective devices to prevent damage during mounting and dismounting operations
? ?? ?Regulated air pressure to protect user and wheel assembly
? ?? ?Approved lubricant to avoid wheel slip and damage to the wheel
For further information regarding equipment meeting the requirements for this program, call 1-800-GM-TOOLS.
Important: ?When mounting the tires, rubber lubricant, GM P/N 12345884 (in Canada, 5728223), must be used. Also, the vehicle should not be driven aggressively (hard acceleration or braking) for at least 6-8 hours after tire mounting to allow the lubricant to dry. Failure to do so may cause the tire to slip on the rim. This condition will affect wheel balance which could result in a vibration.
Balancing
MC style coated weights are recommended and will provide the best balancing of the tire-wheel assembly. If stick-on weights are used, be sure to follow the manufacturers' recommended installation procedure making sure the surface is clean and dry. Using the incorrect type of weights could result in improper fit, and such weights may fall off the wheel.
Balancing of the tire and wheel assembly must be performed on a computerized balancer, capable of static and dynamic wheel balance modes. Assemblies should be balanced to within 1/4 ounce on either rim flange. Proper cones and adapters should be used, free of nicks and burrs to ensure proper balancing.
Wheels
Wheel (Lug) Nuts
Each wheel nut should be torqued in the appropriate torque sequence (refer to graphic) and to 190 N?m (140 lb ft). The torque should be re-checked after the first 160 km (100 mi). To help protect the wheels from theft, a wheel lock kit is also available.
Caution: Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts.
Care / Cleaning
Use soap, hot water and a 100% cotton cloth to clean and polish the new wheels. If using a wheel cleaner, be sure to select one that will not harm the wheel surface, such as GM Chrome and Wire Wheel Cleaner, P/N 1052929 (in Canada, use 10953202). 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.
Vehicle Modifications
Tire Label
After installing the recommended P275/55R20 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 Type/Pressure Selection
To provide a more accurate function of the Tire Pressure Monitoring System, it is necessary to update the Remote Control Door Lock Receiver (RCDLR) with the correct tire type and pressure information. Using the Tech 2?, follow the steps listed below to select the appropriate tire type/pressure:
Install the scan tool.
Turn ignition ON with the engine OFF.
Enter "Diagnostics" and build the vehicle according to model year, vehicle line, etc.
Select: "Body".
Select "RCDLR Module."
Select: "Module Setup".
Select: "Tire Type/Pressure Selection".
Select P-Metric Standard.
Select the front and rear tire pressure as noted on the new vehicle driver door placard sticker for the accessory wheels/tires.
Verify that the selections made are correct and press the enter key. The scan tool will flash "Procedure in Progress", then display "Procedure Complete."
Press the "exit" key to escape.
Tire Pressure Monitor (TPM) System
Important: Tire pressure sensors for 2007 model year full-size utilities are not compatible/interchangeable with pre-2007 model year full-size utilities and vice versa.
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
Turn ON the ignition, with the engine OFF.
Apply the parking brake.
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? to initiate the learn process. A horn chirp will sound indication the mode has been enabled.
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.
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
After the LR sensor has been learned, turn OFF the ignition to exit the learn mode.
After the learn mode has been exited, adjust all tire pressures to the recommended PSI.
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.
