Balanced tire system is essential for gentle driving, while improving longevity. Unbalanced tires cause the car to vibrate, making the driver tired, tires quickly damaged and rigs quickly worn out. Tires must be balanced when first assembling the wheel or reassembling after repair. Tires need to be adjusted immediately if there is a phenomenon of vibration or "reverse". Fluttering outside the cause of alignment may also be due to underlying mechanical problems.
