How to Check Car Tire Wear?

Tire wear can be checked by looking for a molded mark on the tire shoulder, which is evenly divided into five parts around the circumference. On the tire tread surface, along the five equal parts of the tire circumference, there is a 1.6mm high ridge axially set at the bottom of the tread groove. When the tire tread wears down to 1.6mm from the groove bottom, this part of the groove begins to break, resulting in a clear crack, alerting the driver that the tire must be replaced. Additional Information: 1. The sidewall of a car tire displays the tire specifications, brand, manufacturer's standard wheel hub, production number, and maximum load code, all imprinted by a mold. 2. When the tire tread wears down to less than 1.6mm remaining in the groove, skidding often occurs, increasing fuel consumption. This not only affects the vehicle's handling but also easily leads to traffic accidents.
To check car tire wear, I think the most practical method is daily observation. Tread depth is key, and you can use a coin to test it. Take a one-yuan coin and insert it vertically into the tire tread groove. If the serrated edge of the coin is fully visible, the wear is quite severe, and the tire needs to be replaced. Also, pay attention to uneven wear on the tire surface, such as one area being significantly thinner while another is still fine. This could be due to incorrect tire pressure or misaligned wheels, requiring a visit to the repair shop for adjustment. I usually glance at my tires before driving, especially before long trips. Regular checks can prevent blowouts and extend tire life. It's generally recommended to inspect them monthly or check the tire pressure when refueling.
From a safety-focused perspective, checking tire wear is crucial for driving safety. I usually inspect tires with simple tools: using a toothpick or a dedicated tread depth gauge to measure the tread depth. If it's below 1.6 mm, replacement is mandatory. Additionally, pay attention to wear patterns: faster wear in the center often indicates overinflation, while severe edge wear usually suggests underinflation—both can cause vehicle drift or braking issues. I also examine the tire sidewalls for bulges or cracks, as these minor issues can be hazardous at high speeds. Don’t forget to rotate tires regularly, every 8,000 kilometers, to ensure even wear and reduce replacement costs. Safety comes first—address any abnormal wear immediately.
