Abstract:
1. A method for operating a vehicle wheel service system having a wheel mounting structure upon which a vehicle wheel assembly is mounted for rotation during a measurement or service procedure, and a load roller assembly disposed in operative proximity to said wheel mounting structure, said load roller assembly including a load roller for applying a controlled load to the vehicle wheel assembly mounted to said wheel mounting structure during rotation, the operating method comprising: mounting the vehicle wheel assembly onto said mounting structure; rotationally driving said vehicle wheel assembly on said mounting structure in a first rotational direction; measuring an imbalance of the vehicle wheel assembly during said rotation; following measurement of said imbalance, engaging said load roller of said load roller assembly with a surface of the rotating vehicle wheel assembly; subsequently measuring radial forces and/or runout of the vehicle wheel assembly during said rotation of the vehicle wheel assembly in said first rotational direction and while in engagement with said load roller; and presenting an operator with a display of information associated with said measured imbalance before measuring said radial forces and/or runout of the vehicle wheel assembly is completed.
