Abstract
A wheel balancer is provided that includes a shaft adapted for receiving a wheel/tire assembly, the shaft having a longitudinal axis and being rotatable about the axis so as to rotate a wheel/tire assembly removably mounted thereon, a sensor assembly for measuring the rotation of the shaft about its longitudinal axis, a vibration sensor assembly for measuring vibration of the wheel/tire assembly as the wheel/tire assembly is rotated, a motor operatively connected to the shaft for rotating the shaft about its longitudinal axis, a load roller for applying a force greater than 150, pounds in a generally radial direction to the wheel/tire assembly during rotation of the wheel/tire assembly and a control circuit responsive to measurements from the vibration sensor assembly to determine imbalance.
