Removal Procedure

WARNING: This page is about a different car, the 2008 Pontiac G5 and 2008 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use a tire changing machine in order to dismount tires. Do not use hand tools or tire irons alone in order to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result.
NOTE: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel.
IMPORTANT: Use only the Rim-Clamp tire changer for aluminum or alloy rims.
  1. Install the tire and wheel assembly on the tire changer.
    2. NOTE: Damage to either the tire bead or the wheel mounting holes can result from the use of improper wheel attachment or tire mounting procedures. It takes up to 70 seconds for all of the air to completely exhaust from a large tire. Failure to follow the proper procedures could cause the tire changer to put enough force on the tire to bend the wheel at the mounting surface. Such damage may result in vibration and/or shimmy, and under severe usage lead to wheel cracking.
  2. Completely deflate the tire.
  3. Break the tire bead from the wheel.
  4. Remove the tire pressure monitoring sensor, refer to Tire Pressure Indicator Sensor Replacement .
    5. NOTE: When mounting the tires, use an approved tire mounting lubricant. DO NOT use silicon or corrosive base compounds to lubricate the tire bead and the wheel rim. A silicon base compound can cause the tire to slip on the rim. A corrosive type compound can cause tire or rim deterioration.
  5. Apply an approved lubricant to the tire bead and the wheel.
  6. Position the mounting/dismounting head so that the tire iron, or the pry bar can be inserted between the tire and the wheel.
  7. Using the tire machine, rotate the tire/wheel assembly to allow the tire bead to be removed from the wheel.
  8. Repeat the previous steps to remove the inner tire bead.
