The Tire Wizz tool makes mounting and dismounting tires easy. Simply place the disc in the center of the wheel, then use the mechanical advantage provided by one of the specially designed levers to either mount or dismount the tire from the rim.
The complete tool comes with one disc and two levers. The discs are available for either cast (magnesium or aluminum) or spun aluminum wheels. Or, you can purchase a set that includes both styles of disc and one set of levers.
