Safety is the main reason for balancing the wheels and tyres on your vehicle. Balancing will help ensure a smooth, vibration free ride, as well as improving tyre life.
When the wheels on your car have an imbalance, the most notable effect is that the steering wheel will vibrate in your hands or the seat vibrates. As tyre and wheel assembly is vibrating, the contact pressure of the tyre on the road varies, which can cause irregular wear and will, in turn, result in premature tyre replacement.
Wheels should be balanced when new tyres are fitted, when the tyre is removed from the rim, and at regular intervals to take into account any variation in tyre balance from irregular wear.
Correct alignment is critical to safely controlling your vehicle, braking stability, extending tyre life, and ensuring a comfortable ride. It is extremely important that your vehicle's front wheels are aligned to the rear wheels, and where possible all four wheels should be aligned.
