Tires/Wheels
Tires
GM offers two tires; the Bridgestone Dueler Alenza HL P255/55R20 107H AL3, GM P/N 19162355 or 19239588, to be used in conjunction with
the 20" accessory wheels. The Bridgestone Dueler Alenza HL tire has a Tire Performance Criteria (TPC) spec, molded on the sidewall, that 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:
2016 GMC Truck Acadia AWD V6-3.6L Page 270
- 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, 88863415), 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
Use only stick-on weights mounted on the outboard center of the rim (behind the spokes).
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 Nm (140 lb ft). The torque should be rechecked
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
Vehicle Modifications
Tire Label
After installing the recommended P255/55R20 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锟斤拷C (65锟斤拷F). The label is provided as a guide for tire inflation pressures and information relevant to
occupant/cargo capacities.
Tire Pressure Monitor System/TPM Sensor Relearn
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).
2016 GMC Truck Acadia AWD V6-3.6L Page 271
TPM Sensor Relearn Procedure
Note
If using the scan tool to enable the learn mode, J-46079 must be used to activate the sensors. When this preferred method is used, any stray sensor
signals will not affect the learn procedure. In the event a particular sensor's information is displayed on the special tool upon activation but the horn
does not chirp, it may be necessary to rotate the wheel valve stem to a different position due to the sensor signal is being blocked by another
component.
If using the keyless entry transmitter or DIC buttons to enable the learn mode, J-46079 or Pressure Increase/Decrease Method may be used. Before
proceeding with this method, ensure that no other learn procedure is being performed simultaneously or that tire pressures are not being adjusted on
another TPM equipped vehicle within close proximity. Stray signals from other TPM equipped vehicles just driving by can be inadvertently learned.
If any random horn chirps are heard from the vehicle while performing the learn procedure, most likely a stray sensor has been learned and the
procedure will need to be cancelled and repeated. Under these circumstances, performing the TPM Learn Procedure away from other vehicles would
be highly recommended. In the event a particular sensor activation does not cause the horn to chirp, it may be necessary to rotate the wheel valve
stem to a different position due to the sensor signal is being blocked by another component.
Preferred Scan Tool/Keyless Transmitter Learn Enable Method
Preferred Scan Tool Learn Enable Method
1. Using a scan tool, initiate the TPM Learn Mode. A double horn chirp will sound indicating the Learn Mode has been enabled. The left front
turn signal will also be illuminated.
2. Starting with the left front tire, active the sensor by holding the antenna of J-46079 aimed upward against the tire sidewall close to the wheel
rim at the valve stem location. Press and release the Activate button and wait for a horn chirp. Once the horn chirp has sounded, the sensor
information is learned and the turn signal in the next location to be learned will illuminate.
3. After the horn chirp has sounded and the right front turn signal is illuminated, repeat step 2 for the remaining 3 sensors in the following order:
1. Right front
2. Right rear
3. Left rear
4. When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the RCDLR exits the learn
mode.
5. Ignition OFF, adjust all tires to the recommended pressures.
Alternate Keyless Entry Transmitter or DIC Learn Enable Method
1. Ignition ON, initiate the TPM Learn Mode using one of the following procedures:
- On vehicles equipped with keyless entry, simultaneously press the keyless entry transmitters lock and unlock buttons until a double horn
chirp sounds indicating the Learn Mode has been enabled. The left front turn signal will also be illuminated.
- On vehicles not equipped with keyless entry, press and release the driver information center (DIC) INFO button until the TIRE LEARN
message appears on the DIC display. Press and hold the SET/RESET button until a double horn chirp sounds indicating the Learn Mode
has been enabled. The left front turn signal will also be illuminated.
2. Starting with the left front tire, learn the tire pressure using one of the following methods:
- Hold the antenna of J-46079 aimed upward against the tire sidewall close to the wheel rim at the valve stem location. Press and release the
activate button and wait for a horn chirp. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next
location to be learned will illuminate.
- Increase/decrease the tire pressure for 8-10 seconds then wait for a horn chirp. The horn chirp may occur before or up to 30 seconds after
the 8-10 second pressure increase/decrease time period has been reached. Once the horn chirp has sounded, the sensor information is
learned and the turn signal in the next location to be learned will illuminate.
3. After the horn chirp has sounded and the right front turn signal is illuminated, repeat step 2 for the remaining 3 sensors in the following order:
1. Right front
2. Right rear
3. Left rear
4. When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the RCDLR exits the learn
mode.
5. Ignition OFF, adjust all tires to the recommended pressures.
