SERVICE INFORMATION

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 24km (15mi) 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 spotting condition.
