Buick Regal Tire Rotation Pattern and Interval

1. Rotate the tires every 12 000 km (7,500 mi), following the Maintenance Schedule.
2. Use the rotation pattern shown in the manual, and leave the compact spare tire out of the rotation.
3. After rotating, set the front and rear tires to the pressure on the Tire and Loading Information label.
4. Reset the Tire Pressure Monitor System.
5. Check that all wheel nuts are properly tightened.

• The manual's rotation pattern is a diagram, so the text does not say which tire moves to which position.
• Rotate as soon as possible if unusual wear appears, and check inflation and for damaged tires or wheels.
• After a rotation, lightly coat the inner diameter of the wheel hub opening with wheel bearing grease, keeping it off the mounting surface and nuts.
