Tires

GM offers two tires; the Goodyear Eagle RSA P255/60R19 108H AL3, GM P/N 19162231 (Acadia, OUTLOOK) and the Michelin Latitude TR P255/60R19 108S ALS, GM P/N 19162478 (Enclave only), to be used in conjunction with the 19" accessory wheels. The Goodyear Eagle RSA tire has a Tire Performance Criteria (TPC) spec of 1263MS and the Michelin Latitude TR has a TPC spec of 1278MS, 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, 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

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.
