GM Service Manual Online
For 1990-2009 cars only

Important: Tire rotation is not recommended if your vehicle is equipped with different size tires front to rear. Refer to the tire placard on the vehicle to determine OE tire sizes.

If the vehicle is equipped with the same size tire front to rear, rotate the tires and wheels at frequent intervals to equalize wear. In addition to scheduled rotation, rotate the tire and wheel whenever uneven tire wear is noticed.

Due to dissimilar front and rear tire sizes, the tire and wheel assemblies cannot be rotated.
