When a tire is installed on a wheel rim, it is followed by a balancing process. The purpose of the balancing is to eliminate any vibration which might be caused by any mismatch between a tire and the wheel. First, you may wonder why there might even exist a mismatch requiring tire balancing when you're buying new tires. Tire balancing can correct vibration caused by as little as .25 of an ounce of mismatched weight. If it is only attended to when there is a noticeable vibration in the ride or is felt via the steering wheel, it may have already caused considerable stress on your vehicle
-Always balance new tires when they are installed
-Check tires for proper balance whenever tire rotation is performed at intervals of 4,000 to 6,000 miles.
-Have any tire which is repaired, balanced again to compensate for the weight change produced by the patch or the damage being fixed.
Sometimes the wheels and tires on a vehicle may be in balance but you can still feel a vibration. Here are some of the other causes of vibration:
-Wheel alignment is out
-Low Tread
-Bent wheel
-Wheel-to-axle mounting error
-Brake component issues
-A tire is out of round
-Drive train component issues
-Suspension issues
-Wheel bearing
