Abstract
A device which can be retrofitted onto existing passenger vehicle rim holding tire changers or provided as a feature of such equipment by the original equipment manufacturer. An operator rolls a tire into contact with the device and the device lifts the tire, causing it to spin and come to rest adjacent a bead loosener shoe with a different section of the tire facing the shoe. The device includes a pair of parallel rollers arranged at different heights and spaced slightly from each other. The roller that is relatively lower is closer to the operator while the higher roller is to the rear of the tire changer. The rollers extend perpendicularly from the side of the tire changer. When a tire is rolled into contact with the device, it engages the lower roller first and bounces up to become slightly airborne. The bounce causes the tire to spin relative to its rolling path. The tire then engages both rollers and cradles on them in a resting position. However, because the two rollers can rotate, the tire continues to spin slightly as it rests on the rollers, thus rotating the tire relative to its previous position. A bead loosener shoe adjacent the tire changer forces the tire form the ri…
