Correcting Non-Uniform Tires

There are two ways to correct tires that cause a vibration even though they are properly balanced. One method uses an automatic machine that loads the tire and buffs small amounts of rubber from high spots on the outer two tread rows. Correction by this method is usually permanent and, if done properly, does not significantly affect the appearance or tire tread life. Tire trueing with a blade-type machine is not recommended as this reduces the tread life substantially and often does not permanently correct the problem.

Another method is to vector the tire and wheel assembly.
