What is a Wheel and Tire Balance?
Wheel and tire balancing help to evenly distribute the weight of tires. This helps to ensure that the assembly will spin correctly and smoothly at high speeds. When the tires are being balanced, it involves them being placed on a balancer. Wheels are never exactly the same weight the whole way around. The valve stem hole can take a small amount of weight from one side of the wheel. The tires themselves will also have slight imbalances in weight.
