Summary
This informational bulletin advises the tech of a different tire/rim option that can be used to correct the customers concern.
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.
Correction
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.
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. .
