Centercap Interchangeability?


Recommended Posts

I'm looking at sets of the 18" wheels from the '07 Escalade on e-bay, but I'm not so sure that I like the big Caddy emblem on the centercap - would look out of place on my RCLB pickup, I think.

 

Are there other centercap options for this wheel?

 

Thanks for reading.

Read this bulletin on the interchangabilty on the wheels from the "New-for'07" SUV's to the '99-current pickups.

Although it pertains to the 20" and 22" wheels,The offset issue also applies to the standard 18" wheels...........

 

 

Subject: Info - 20 Inch and 22 Inch Accessory Wheels Available Through GM Accessories #06-03-10-001B - (05/01/2006)

 

 

 

Models: 2007 Cadillac Escalade, Escalade ESV, Escalade EXT (20" and 22")

 

2007 Chevrolet Avalanche, Suburban, Tahoe (20" Only)

 

2007 GMC Yukon, Yukon XL (20" Only)

 

2007 GMC Yukon Denali, Yukon Denali XL (20" and 22")

 

 

 

 

--------------------------------------------------------------------------------

 

This bulletin is being revised to add information on 22" wheels available for Denali models. Please discard Corporate Bulletin Number 06-03-10-001A (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 20" or 22" wheels and tires, which are available through GM Accessories. This guide will cover the required vehicle modifications, module reprogramming and warranty information.

 

Important: 20" and 22" accessories wheels released for 2007 model year full-size utilities are NOT compatible/interchangeable with pre-2007 model year 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.

 

Vehicle Modifications

Tires (20")

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.

 

Tires (22")

GM offers one tire, the Bridgestone Dueler H/L Alenza P285/45R22, to be used in conjunction with the 22" accessory wheels. The Bridgestone Dueler tire has a Tire Performance Criteria (TPC) spec of 1261MS (molded on the sidewall) which meets or exceeds all Federal Safety guidelines.

 

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.

 

Tire Label

After installing the recommended tires, place the provided tire label on the vehicle. The tire label should be located on the door jamb, near the original tire label, and should not cover up the original tire label. 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 engine OFF.

Enter "Diagnostics" and build vehicle according to model year, vehicle line, etc.

Select "Body."

Select "RCDLR Module."

Select F2: Module Setup.

Select F5: 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 trucks and utilities and vice versa.

 

To avoid system malfunctions, it is necessary to install tire pressure sensors in the accessory wheels. Replacement sensors GM P/N 19155710 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.

Important: If the learn mode cannot be enabled, ensure the TPM system is enabled in the RCDLR. Use the following steps to enable the TPM system.

 

Install the Tech 2® to the vehicle.

Turn ON the ignition, with the engine OFF.

Enter "Diagnostics" and build vehicle according to model year, vehicle line, etc.

Select "Body."

Select "RCDLR Module."

Select "Module Setup."

Select "TPM Option Enable."

Press the exit key to escape.

 

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 scan tool and select Special Functions/Sensor Learn Mode Enable/Enable soft key. 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.

Spare Tire Hoist (22" Wheels Only)

Important: The new spare tire hoist is necessary due to the added amount of stress that the 22" wheel/tire system causes to the factory installed tire hoist. The tire hoist is also needed even if you do not put a 22" spare under the vehicle.

 

Replace the spare tire hoist with GM P/N 19158309. This modification is required for the following vehicles when installing 22' wheels.

 

• 2007 Cadillac Escalade

 

• 2007 Cadillac Escalade ESV

 

• 2007 Cadillac Escalade EXT

 

• 2007 GMC Yukon Denali

 

• 2007 GMC Yukon Denali XL

 

The following procedure should be followed for this modification.

 

If the vehicle is equipped with a spare tire stowage lock cylinder, open the spare tire lock cover on the bumper and using the ignition key, remove the lock.

Rotate the hoist shaft counterclockwise in order to lower the spare tire to the ground. Continue to rotate the shaft until the spare tire can be pulled out from under the vehicle and removed. If the spare tire does not lower to the ground, the secondary latch is engaged causing the tire not to lower.

If the secondary latch is engaged and the cable end is visible, perform the following procedure:

3.1. Tighten the cable by rotating the hoist shaft clockwise until you hear two clicks or feel it skip twice. You cannot overtighten the cable.

 

3.2. Loosen the cable by rotating the hoist shaft counterclockwise 3 or 4 turns.

 

3.3. If the spare tire can be lowered, repeat steps 1 and 2 to see if the spare tire can be removed.

 

3.4. If the spare tire cannot be lowered, rotate the hoist shaft counterclockwise until approximately 152 mm (6 in) of cable is exposed.

 

3.5. Raise and support the vehicle.

 

3.6. Place a transmission jack, or equivalent, under the spare tire.

 

3.7. Position the center of the transmission jack under the secondary latch release button at the center of the spare tire. Arrange the arms of the transmission jack so they will support the tire after it has been released.

 

3.8. Raise the jack until the spare tire stops moving upward and is firmly held in place, releasing the secondary latch.

 

3.9. Lower the tire. If the spare tire is hanging by the cable, rotate the hoist shaft counterclockwise until the tire is low enough to remove.

 

If the secondary latch is engaged and the cable end is NOT visible, perform the following procedure:

4.1. Raise and support the vehicle.

 

4.2. Place a transmission jack, or equivalent, under the spare tire.

 

4.3. Position the center of the transmission jack under the secondary latch release button at the center of the spare tire. Arrange the arms of the transmission jack so they will support the tire after it has been released.

 

4.4. Raise the jack until the spare tire stops moving upward and is firmly held in place, releasing the secondary latch.

 

4.5. Lower the tire and remove it from the jack.

 

Raise and support the vehicle if it is not already raised.

Depress the tabs, remove the guide shaft from the hoist collar, and slide the shaft toward the bumper.

Remove the collar from the hoist.

Remove the bolt.

Remove the hoist from the bracket.

Remove the spare tire hoist shaft guide from the bumper.

Install the spare tire hoist shaft guide to the bumper.

Install the hoist to the crossmember.

Install the bolt.

Tighten

Tighten the bolt to 40 N·m (30 lb ft).

 

Install the collar to the hoist.

Install the shaft to the hoist.

Install the spare tire to the hoist.

Rotate the hoist shaft clockwise until the spare tire is in position and the hoist clicks two times or it skips twice. You cannot overtighten the cable.

Remove the safety stands.

Lower the vehicle.

Install the spare tire stowage lock cylinder.
