Tires/Wheels - OE Tire Shake/Vibration Information

INFORMATION

Bulletin No.: 03-03-10-007G

Date: July 13, 2012

Subject: Information on Tire/Wheel Characteristics (Vibration, Balance, Shake, Flat Spotting) of GM Original Equipment Tires

Models:

2013 and Prior GM Passenger Cars and Light Duty Trucks

Supercede:

This bulletin is being revised to add a reference to GM approved tire force variation measurement equipment. Please discard Corporate Bulletin

Number 03-03-10-007F (Section 03 - Suspension).

The purpose of this bulletin is to help explain that, under certain circumstances, a customer may notice a slight tire shake within the first few

miles/kilometers of vehicle operation.

Tires may be designed with a nylon overlay configuration engineered to enhance the tire's integrity at high speeds. This allows the tires to be driven

at higher speeds without excessive heat buildup.

Important

Before measuring tires on GM approved tire force variation measurement equipment, the vehicle MUST be driven a minimum of 24 km

(15 mi) to ensure removal of any flat spotting (The tendency to "flat spot" is less likely as the tire accumulates mileage).

When parked overnight, or for a period of time, the tires may set (flat spot) and require a few miles/kilometers before heating up to their normal

operating temperature. Until the tires warm up, a slight tire shake may be felt but should subside quickly.

Important

DEALERS SHOULD REFRAIN FROM ATTEMPTING REPAIRS OR REPLACING COMPONENTS for this temporary tire flat
