Correcting Vehicle Shake

Abstract The mechanisms which cause shake on smooth roads and the procedures and equipment for removing it are reviewed. A critical comparison of various on‐ and off‐the‐car tire balancing methods is made. The effectiveness of tire grinding and trueing is reviewed with emphasis on the total system behavior. A statistical evaluation and analysis is presented of the potential errors contributed by off‐the‐car balancing and the vehicle itself, considering the imbalance vector components inherent in tire‐rim assemblies and vehicle axles. The use of a liquid tire balancer is also investigated.
