The invention provides a tire changing and balancing machine. On the same shaft used to mount and demount a tire, a wheel assembly is balanced. A tire on a wheel assembly is placed between a breaker blade and a breaker pad. The breaker blade collapses the tire. The wheel assembly is then mounted on a shaft. A mounting and demounting head is used to remove the tire from the wheel assembly. A new tire is placed on the wheel assembly. The mounting and demounting head is then used to mount the new tire on the wheel assembly. The wheel assembly and mounted tire are then spun on the shaft and balanced.

Tire changing and balancing machine

A combination tire and rim assembly match mounting, match grinding and balancing machine has a load roller for contacting the mounted tire periphery with a predetermined force. The displacement of the roller provides a measure of tire radial runout and either a vision system or mechanical probes provide a measure of rim radial runout. A controller operates to calculate the least square best fit between the tire and the rim and to control the match grinding to provide improvement in the tire and rim assembly operating vibration characteristics.
