Due to the influence of factors such as the front wheels bearing large loads, steering, and driving, the wear is significantly faster than the rear wheels, so it is recommended to swap the front and rear wheels every 10,000 kilometers.

Four-wheel rotation is to detect whether the angles of each wheel of the tested vehicle and the toe angle meet the OEM standard through a four-wheel alignment machine. If they do not meet the standard, random adjustments can be made.

When the tires and wheel phases have been separated and reassembled, or the vehicle experiences significant steering wheel shake after prolonged use, it is necessary to consider re-dynamic balancing of the tire assembly.

The role of four-wheel alignment is to make the car hold a stable straight line driving and steering light, and reduce the wear and tear of tires and steering components in the car. Due to the different design and manufacture of the original four-wheel alignment by each automobile manufacturer, the various camber and beam values of each wheel are different, and there are adjustable and non-adjustable parts. To do four-wheel alignment is through the four-wheel alignment device, detects the vehicle being measured by the various wheel camber and beam value is in line with the original standard, such as not in line with the special adjustments can be made.
