Background

The tire is the only ground-contacting component of the vehicle, and provides the driving, steering and braking force required by the vehicle movement. For automobiles, especially operating vehicles, in addition to fuel, tires are the most consumed in use. The service life of the tire is closely related to the condition of the automobile. For a new vehicle, the success or failure of the chassis teaching determines the service life of the tire of the vehicle after leaving the factory to a certain extent; for old vehicles, especially commercial vehicles with severe service conditions, due to factors such as heavy load, poor road conditions, lack of maintenance and the like, irregular wear of tires occurs frequently, and the service life of the tires is greatly shortened.

Conventional tire patterns, whether longitudinal, transverse or cross-country, are mostly continuous, smooth-surfaced curvature pattern blocks except for grooves, so as to meet the requirements of wear resistance and puncture resistance. However, for the bench and road test before the delivery of a new vehicle, whether the abrasion form of the tire is reasonable or not is difficult to find due to the short test period; for old vehicles, attention can be paid only when the tires are worn too fast and the wear surfaces are extremely abnormal. In the two cases, the depth of the residual groove is difficult to reflect through visual observation or measurement, and finally, the service life of the tire is greatly reduced and irreversible, which undoubtedly causes adverse effects on the time of new vehicles in a host factory or public praise of market use and the vehicle cost of end customers.
