Tire Balancing
Balance is the easiest procedure to perform and should be done first if the vibration occurs at high speeds. Do an off-vehicle, 2-plane dynamic balance first to correct any imbalance in the tire and wheel assembly.
An on-vehicle finish balance will correct any brake drum, rotor, or wheel cover imbalance. If balancing does not correct the high-speed vibration, or if the vibration occurs at low speeds, runout is the probably cause.
