At a speed of 100 km/h, the centrifugal force of a 10 g imbalance is equal to that of a sledge hammer.
Double this speed and the forces involved quadruple. Vehicles with poorly balanced wheels become dangerous:
More stress on wheel suspension components and bearing points
Noticeable vibrations on the steering wheel and in the interior
Body subjected to greater physical stress
Increased brake wear
Increased heel and toe wear on tyres
Braking distance increases
