Wheel balancing—also known as tire balancing—is the process of equalizing the weight of the combined tire and wheel assembly so that it spins smoothly at high speed. Balancing involves putting the wheel/tire assembly on a balancer, which centers the wheel and spins it to determine where the weights should go.
You will need tyre balancing as soon as you purchase new tyres for your vehicle. This process is performed in order to ensure that all of the tyres are balanced with the wheel weights to ensure the smooth running of each of the tyres. When there is an imbalance in your tyres, the steering wheel will rock back and forth as you drive, especially when you drive at a certain speed. When you notice this happening, you should contact a mechanic to fix the problem straight away as it can be very dangerous to drive with imbalanced tyres.
