Condition
Some customers may comment on poor ride quality at highway speeds.
Cause
This condition may be caused by tire inflation pressure that is high to handle load
capacity of the truck. If the truck is driven unloaded, then the road inputs may give a
harsh ride for the occupants.
Important: This is not a warranty concern, but an option and any action taken would be
a customer pay event.
Note: Techline will need to be contacted to update the calibration to correct the
speedometer.
Correction
Verify that there are no imbalance or road force issues with the tires.
If the tires are within balance and RF specs and the ride quality is still undesirable, to
improve ride quality, the Accessory Group has released an 18" or 20" wheel and tire for
this model of truck. Refer to the Accessory Site for available wheels and tires system.
The spare tire and wheel will have to be replaced with the production 18" spare to provide
the correct circumference tire to work properly with the ABS and stability system. .

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
