Incorrectly balanced wheels can cause vibration in the steering wheel at road speeds of around 50-70 mph. As a result of wheels being out of balance, this also leads to premature tyre wear as well as poor handling.
Wheel balancing is simply adjusting the balance between the tyre and the rim using weights.
Wheel alignment is making sure the wheels on your vehicle are perpendicular to the road and that the wheels are parallel to each other. We use correct vehicle manufacturing tolerances to set up all four wheels. It improves handling and tyre wear.
