Locate the wheel weights on the inboard rim flange. If during static balancing more than 28 grams (1 ounce) is needed, split the weights as equally as possible between the inboard and outboard flanges.

Special polyester-coated clip-on wheel weights are to be used to balance factory aluminum wheels. These weights are designated MC (1) or P (3), and must be used on aluminum wheels having a wide, 7.6 mm (19/64 in) flange. A plastic tipped hammer should be used to prevent damage to the weight's coating during installation.

Adhesive wheel weights are also available. Use the following procedure to install adhesive wheel weights.

  1. Determine where the wheel weight is to be located on the inboard side of the wheel and clean that area by sanding it to bare aluminum. Do not sand the outboard side of the wheel as this will damage the clear coat finish.
  2. Wipe the sanded area with a mixture of half ispopropyl alcohol and half water. Use a clean cloth or paper towel.
  3. Dry the area with hot air until the wheel surface is warm to the touch.
  4. Warm the adhesive backing on the wheel balance weight to room temperature.
  5. Remove the tape from the back of the weight. Do not touch the adhesive tape.
  6. Apply the wheel weight and press on with hand pressure.
  7. Secure the wheel weight with a 70 to 110 N·m (16 to 25 lb ft) force applied with a roller.
