This bulletin is being revised to update the model years. Please discard Corporate Bulletin Number 05-03-10-011D (Section 03 - Suspension).
The purpose of this bulletin is to provide a reference guide for the technician to upgrade a vehicle from factory wheel and tires to 18" 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 Pirelli P-ZERO ROSSO 215/45R18, to be used in conjunction with the 18" accessory wheels. The Pirelli tire has a Tire
Performance Criteria (TPC) spec of #1255, 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
Caution:
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.
ALUMINUM WHEELS REQUIRE SPECIAL WHEEL NUTS. Each wheel nut should be tightened to 140 Nm (100 lb ft) using the tightening sequence
illustrated above. 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.
