At high speeds, tires generate enormous centrifugal forces. Even tiny irregularities of only a few grams in the tire are multiplied by many orders of size.

Such imbalance stresses tires and suspension. This weight irregularity can be tested and identified at tire dealerships and is balanced by adding small counter-weights.

Every time a tire is fitted to a wheel, it should be balanced.
