After the rear wheel repair tire, you must do the dynamic balance, especially the tire is disassembled and repaired, which must be the down-motion balance.
As long as the tires and hubs are disassembled, then the dynamic balance needs to be done. Whether it's changing the tires or changing the wheels, even if nothing is changed, just pull the tires off the rim and check it, as long as the wheels and tires are assembled again, you must do a dynamic balance.
Dynamic balance can directly endanger the safety of safe driving, if there is no dynamic balance after the tire repair, it will prompt the rudder can not be stable rotation, the car will cause jitter, the steering wheel vibration of the car when driving, especially at high speed, the higher the speed, the more significant the jitter.
When you need to do dynamic balancing
1. Replace the new tire or after the accident of repair.
2. Front and rear tires are one-sided bias grinding.
3. The steering wheel is too heavy or floating and shaking when driving.
4. If your car shakes and the steering wheel shakes when driving or turning.
5. Individual vehicles will also be used for too long, resulting in "counterweight blocks" falling off, and the balance of tire counterweights is unbalanced.
The harm of not moving the balance:
1. The abnormal state of the wheel will reduce the sense of maneuvering of the car, and the steering wheel will be shaken seriously.
2. When driving to a specific speed range, the vehicle will resonate.
3. Increase the driving resistance of tires and increase fuel consumption.
4. If it is serious, it may affect the suspension, bearings, etc.
5, it is important that at high speeds may involve personal safety, such as flat tires, uncontrolled direction, rollover and so on.
