For 1990-2009 cars only

NOTICE: Use a tire changing machine in order to dismount the tires. Do not use hand tools or tire irons alone to remove the tire from the wheel. Damage to the tire beads or the wheel rim could result.

Follow the tire changing machine manufacturer's instructions in order to properly separate the tire from the wheel.

NOTICE: It is important to note that damage to either the tire mounting surface or the wheel mounting holes can result from the use of improper wheel attachment or tire mounting techniques. It takes 70 seconds for all of the air to completely exhaust from a large tire. Failure to follow the proper procedure 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 sever use could lead to cracking.
