Frequently Asked Questions Question: What does a Tire Changer do? Answer: A Tire Changer takes Tires off of Wheels (called demounting) and puts Tires onto Wheels (called mounting). Q: What is the difference between a Tire, Wheel, and Rim? A: A Wheel is the round metal piece that attaches to the Vehicle's axle. A Tire is the round rubber piece that surrounds the Wheel. The outer edge of the Wheel, where the Tire attaches to the Wheel, is called the Rim. Some people use Wheel and Rim interchangeably. Q: What are the steps in the process of demounting a Tire and then mounting a new Tire? A: The steps are: Deflate the Tire, break the Bead, secure the Wheel on the Turntable, demount the Tire, mount the new Tire, inflate the new Tire, then remove the Wheel from the Turntable. Q: What does "break the Bead" mean? A: A Tire is held on the Rim of a Wheel by the Tire Bead sitting between the Rim Lip and the Bead Retainer of the Rim. The air pressure in the Tire holds it in place once the Bead is seated (during mounting). When you "break the Bead", you move the Tire Bead out of the location where it was seated, which is required to take the Tire off of the Wheel. Q: Can I break the Bead without fully deflating the Tire? A: No, do not do this. Always fully deflate a Tire before attempting to break its Bead. The air pressure energy in a Tire, even if not fully inflated, can be considerable. If you were to attempt to break the Bead of a Tire not fully deflated, that air pressure energy would be released all at once, possibly injuring or, in rare cases, killing the Operator or bystanders.

• This is a foot control air valve found on many tire changers. This valve is typically found on all the front foot pedals (clamping jaw pedal, tilt tower pedal, bead breaker pedal) and may also be found on the bead blast / tire fill valve as well.
• Foot pedal valves are the control center of your tire changer. They are used to activate the clamping cylinders, bead breaker, air inflation system and turntable. You can access the foot pedal valves by removing the covers from the sides of your tire changer and spotting the air valves connected to the foot pedals.
• Check the valve fittings and airlines for damage or leaks. Inspect the body of the valve for cracks. Clean any debris around the valve paying close attention to the rod of the valve. Applying a light amount of air tool oil on the rod while cycling the foot pedal will help lubricate the rod seal.
• Activate the foot pedals and check the springs or linkages for proper function and adjust as necessary. If you notice excessive leaks in either foot pedal valves, they will need to be replaced (most people notice a crack in the plastic housing or leaking air from the rod). Rebuild kits are difficult to find and replacement of the entire valve is typical.
