A wheel balancer has a shaft for receiving a wheel/tire assembly, a rotation sensor assembly for measuring rotation of the shaft about its longitudinal axis, a motor operatively connected to the shaft for rotating said shaft about its longitudinal axis, thereby to rotate the wheel/tire assembly, a vibration sensor assembly for measuring vibration of the wheel/tire assembly as the wheel/tire assembly is rotated, and a load roller for applying a generally radial force to the wheel/tire assembly during rotation of said wheel/tire assembly. Movement of the load roller is measured to determine loaded radial runout of the wheel/tire assembly while the force is applied thereto and a a tire stiffness value for the wheel/tire assembly is provided. A control circuit is responsive to the measured vibration of the wheel/tire assembly to determine wheel imbalance, and responsive to the determined imbalance, the measured loaded radial runout of the wheel/tire assembly, and the tire stiffness to determine the locations and magnitudes of correction weights to add to the wheel/tire assembly to reduce the vibration of the wheel/tire assembly when mounted on a traveling vehicle.
