Description

Technical Field

[0001] The present application belongs to the technical field of automobile tires, and in particular relates to a tire for quickly diagnosing vehicle conditions. Background Art

[0002] Tires are the only ground-connected parts of a car, providing the driving, steering, and braking forces required for the car to move. For cars, especially commercial vehicles, tires consume the most in use, in addition to fuel. The service life of tires is closely related to the condition of the car. For new cars, the success or failure of chassis tuning determines the service life of vehicle tires after leaving the factory to a certain extent; for old cars, especially commercial vehicles under harsh conditions, irregular wear of tires is frequent due to factors such as heavy loads, poor road conditions, and lack of maintenance, which greatly shortens the service life of tires.

[0003] Conventional tire patterns, whether longitudinal, transverse or off-road, except for the grooves, are mostly continuous, smooth curvature blocks on the tread to achieve wear resistance and puncture resistance. However, for new cars, it is difficult to find out whether the wear pattern of the tire is reasonable due to the short test cycle during the bench and road tests before leaving the factory; for old cars, attention will only be drawn when the tire wears too quickly and the wear surface is extremely abnormal. These two situations are difficult to reflect through intuitive observation or measurement of the remaining groove depth. When they are finally discovered, the service life of the tire has been greatly reduced and is irreversible, which will undoubtedly have an adverse impact on the launch time of the new car of the OEM or the market reputation and the cost of the car for the end customer. Summary of the invention

[0004] The purpose of the present application is to solve the above-mentioned problem that the existing tires cannot be diagnosed, and to provide a tire for quickly diagnosing the vehicle condition, by evaluating the vehicle condition by the surface wear form of the tire tread pattern in the shortest time.

[0012] Preferably, the tooth-shaped grooves on the fourth tread pattern are at an angle of 90° to the center axis of the tire and are V-shaped grooves or trapezoidal grooves.

[0013] Preferably, the absolute value of the inclination angle θ between the inclined wall of the tooth-shaped groove and the vertical plane of the tire tread is 10-20°; the top spacing L of the tooth-shaped groove is 0.5-0.8 mm, and the height H of the groove is 0.3-0.5 mm.

[0014] Preferably, the above tire is used for rapid diagnosis of vehicle condition.

[0015] A tire for rapid diagnosis of vehicle condition using the above technical solution can be used by car manufacturers to adjust the chassis to the best effect in a short period of time before the car is put on the market by using the wear surface of this new pattern tire, which greatly shortens the road test time of new models; at the same time, it can also avoid adverse feedback after the market to a certain extent.
