Abstract
A device and method for reducing on-car runout and imbalance in a tire/wheel assembly. An on-car runout device has a powered roller that rotates the tire/wheel assembly while it is mounted on the vehicle hub and a runout measuring device that measures the runout of the vehicle hub and a surface of the tire/wheel assembly. The on-car runout device can operate in combination with an off-car balancer in an integrated balancing system, and a computer determines the optimal position and amount of weights to reduce the imbalance. The on-car runout device also minimizes the runout in a tire/wheel assembly by automatically optimizing the position of the tire/wheel assembly relative to the runout of the vehicle's hub. Additionally, when the on-car runout device communicates with an off-car balancer, the integrated system can calculate the balance weights needed to counteract differences in imbalance forces in the tire/wheel assembly due to changes in the tire/wheel assembly's mounting between the off-car balancer and the vehicle hub.
