How do I check tire wear? Tires usually give drivers a long warning before problems occur, so learning to "interpret" these warning signals can put an end to many wear problems, thus extending the service life of tires for thousands of kilometers. Observe whether the tread pattern has the following wear conditions: 1) unilateral wear, that is, one side of the tread pattern is more worn than the other side, that is, the blocks on the same side are uneven; 2) central wear, that is, the tread pattern is more serious than the wear on both sides; 3) Abnormal wear, that is, regular uneven wear of the tread. If this happens, check and adjust the tire pressure, positioning or other related components, and adjust the tire position. Common tire failures

Here are some common questions about tire wear. If you have similar problems with your tires, please click on Accidents and Emergencies for a brief explanation.

Wear of both shoulders: insufficient air pressure, wear of tread center: excessive air pressure, one-sided wear: jagged wear of blocks on the same side due to poor positioning: Is there jagged or feathered wear on the poorly positioned tread? This is caused by uneven tread grounding, which can be corrected by toe-in or toe-in positioning. Cup-shaped wear of tread: the related accessories are seriously worn.

Wear of both shoulders: insufficient air pressure.

If this is the case with tires, it is caused by insufficient air pressure. The natural enemy of tires is low air pressure. Insufficient air pressure will lead to: tire overheating, resulting in tread or ply delamination; The tread groove and shoulder are cracked and the cord is broken; Rapid wear and irregular wear of tire shoulder position; Tire rolling resistance increases and fuel consumption increases; Abnormal friction between tire lip and rim leads to tire lip damage; Or the tire leaves the rim, or even a flat tire! Be sure to check the tire pressure regularly. Abnormal tire wear may also be caused by improper positioning or mechanical failure.

Wear of tread center: too high air pressure.

If the tire pressure is too high, the center of the tread needs to bear the load of the vehicle, which causes the center of the tread to wear faster than both sides and reduces the normal service life of the tire. Excessive air pressure will lead to: when the tire is impacted by external force, it is easy to cause trauma or even explosion; Tread tension is too high, which causes tread delamination and crack at the bottom of tread groove; Tire grip decreases and braking performance decreases; Vehicle suspension system is easy to be damaged; Vehicle jumping, reduced comfort and driving fatigue. Be sure to check the tire pressure regularly. Abnormal tire wear may also be caused by improper positioning or mechanical failure.

Cup-shaped wear of tread: serious cup-shaped wear of related accessories (also called pit or groove wear) is the most common in front wheels, of course, rear wheels may also appear. This indicates poor wheel balance or serious wear of the suspension/steering device of the vehicle.
