The lead weight installed on the car tire is also called the balance weight, which is an indispensable part of the car tire. The main purpose of installing the balance weight on the tire is to prevent the tire from vibrating under high-speed operation and affecting the normal driving of the vehicle. This is what we often call tire dynamic balance. Balance weight, also known as tire balance weight. It is a counterweight component installed on the wheels of a vehicle. The function of the balance weight is to keep the wheels in dynamic balance under high-speed rotation. Generally divided into two types, one is attached to the inner ring of the hub, and the other is installed on the edge of the hub. Don't underestimate the balance weights on car tires, they are very useful!
The wheel of a car is a whole composed of tires and wheels. However, due to manufacturing reasons, the mass distribution of each part of the whole cannot be very uniform. When the wheels of a car rotate at a high speed, it will form a dynamic imbalance, causing the wheels to shake and the steering wheel to vibrate during the driving.
Dynamic balance refers to the asymmetrical weight distribution generated by the force when the tire rotates, usually at a higher speed. In the tire factory, a tire and wheel balancer is installed to test the wheels, the assembly is accelerated to 300 RPM or higher, and the tire rotation sensor measures the force imbalance.
On the inner and outer planes of the wheel, these forces are broken down into static and couple values compared to unbalance tolerances (which is the maximum allowable manufacturing limit). If the tire is not selected, it may wobble and perform poorly. In the tire retail store, check that the tire/wheel assembly is screwed on the balancer, which determines the amount and angle of imbalance.
There are generally two types of balance weights for this kind of tires, one is the paste type and the other is the hook type. Both types of balance weights may fall off after a period of use. Some balance weights with poor tape performance will have a certain bonding gap after being pasted, which will cause the balance weight to be lost during driving. As for the hook-type balance weight, the unreasonable fit clearance is also the cause of its loss during driving. Poor tape performance will also make it difficult to remove residual glue on the balance weight. If this happens, it's best to balance and supplement.
