wheel balance
Nearly all passenger wheels will require wheel weights to ensure that the wheel is correctly balanced before it is fitted back on to the vehicle. It is very rare that a wheel and tyre are perfectly symmetrical and evenly weighted and of course, the tubeless valve will also have an effect of the balance.
Therefore, small pieces of metal are used, known as wheel weights or balance weights to ensure that the wheel and tyre don’t give the feeling of vibration at a certain speed. The wheel weights are applied onto various parts of the rim (depending on the fitment) in accordance with the instruction from the wheel balancer.
