How many tires are generally balanced for dynamic balancing?

[Sawyer]

Dynamic balancing is generally performed on all 4 tires, but it can also be done on a single tire. When a car's wheels rotate at high speeds, they may develop dynamic imbalance, causing symptoms like wheel wobbling and steering wheel vibration during driving. To prevent or eliminate this phenomenon, weights are added to the wheels under dynamic conditions to correct the balance of various edge sections. Tires should undergo regular dynamic balance checks. Tire balancing is divided into two types: dynamic balance and static balance. Dynamic imbalance can cause wheel swaying, leading to wave-like tire wear; static imbalance may result in bumping and bouncing, often causing flat spots on tires. Therefore, regular balance testing not only extends tire lifespan but also enhances driving stability.
