Affected Component: Equipment:other:labels.

Summary: Vehicle description: certain 2-wheel drive pickup trucks fail to comply with requirements of fmvss no. 120, "tire selection and rims for motor vehicles other than passenger cars. " the problem was caused by a computer error that resulted in the certification label listing tire size and inflation pressure information that differ from the tire size and the inflation pressure information for the tires on the vehicle. If the vehicle owner or someone servicing the vehicle inflates the tires according to the pressure specified on the label versus the appropriate pressure for the tires, the tires could be under-inflated or over-inflated depending on the tires mounted on the vehicle. .

Conequence: If the tires are under-inflated, it could reduce the tread life of the tire, and the tire could degrade to a point of allowing sudden air loss. If the tires are over-inflated, it could reduce the tread life of the tire and increase susceptibility to road hazard damage. If sudden air loss or a road hazard causes damage to a tire, control of the vehicle could be adversely affected and could result in a vehicle crash. .

Remedy: Owners will be provided with a new label and installation instructions. However, a dealer can install the label if the owner so desires. Owner notification began may 31, 2001. Owners who do not receive the label and installation instructions within a reasonable time should contact chevrolet at 1-800-222-1020 or gmc at 1-800-462-8782. .
