What causes tyre and wheel vibrations?
Vibrations can be caused by weight variations inside the tyre and eccentricity of the tyre’s diameter. Brands of tyres can be different – some are better than others, but all contain weight and dimensional variations. More technically, vibrations are caused by radial and lateral force variation. Force variation being the result of tyre/wheel, brake drum/rotor inconsistencies. Rotating axle end components and variables in operating conditions cause vibrations as the tyre makes contact with the road surface under load. Radial and lateral force variation is impacted when the tyre meets and leaves the road surface, eventually wearing down your tyre tread. There are so many different causes of force variation that it’s virtually inevitable.
