This bulletin is being revised to add 2011 model year and update information. Please discard Corporate Bulletin Number 09-03-10-012 (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.
Tires
GM offers one tire; the Goodyear Eagle RS-A P245/40R19 94W, GM P/N 19239693 to be used in conjunction with the 19" accessory wheels. The
Goodyear Eagle RS-A has a Tire Performance Criteria (TPC) spec of 1366MS (molded on the sidewall), which meets or exceeds all federal safety
guidelines.
Wheels
Center Cap
Notice
Attempting to "hammer on" the caps may result in damage to the cap.
Install the center cap onto the wheel after the tire has been mounted and balanced, but BEFORE the assembly is installed onto the vehicle. The preferred
method for center cap installation is by hand. As an alternate, use a non-metallic object to push the center cap into place.
Wheel (Lug) Nuts
Warning
Incorrect wheel nuts or improperly tightened wheel nuts may cause the wheel to become loose and even come off. This could lead to an accident. Be sure
to use the correct wheel nuts.
Each wheel nut should be torqued in the appropriate tightening sequence shown above and to 150 Nm (111 lb ft). The torque should be re-checked after
the first 160 km (100 mi).
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. 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.
