How to Check the Tire Safety Line?
3 Answers
The method to check the tire safety line is: 1. Find the raised horizontal bar between the two tread patterns of the tire; 2. Observe whether the tread is flush with the raised bar. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit the torque of traction and braking, ensuring the adhesion between the wheels and the road surface; 3. To reduce and absorb the vibrations and impact forces during driving, preventing severe vibrations and early damage to car components. The maintenance methods for tires are: 1. Regularly clean the stones in the tire gaps; 2. Reduce exposure of tires to sunlight; 3. Promptly check the tire pressure; 4. Pay attention to the maintenance of the suspension; 5. Regularly inspect the front wheel alignment.
I'm a seasoned driver with nearly 20 years of experience, and checking tire wear indicators is a habit of mine. Simply put, the wear indicator is a small raised bar inside the tire tread grooves, designed to be about 5-6 mm in height. When the tire wears down to this level, it's time for replacement. The checking method is quite easy: first park the car on level ground, ensure the engine is safely turned off, then squat down and use your fingers or eyes to slowly trace along the tire surface to locate that raised marker. You can also use a 1-yuan coin to help: insert it into the tread groove - if the national emblem on the coin becomes fully visible, it indicates excessive wear. If not addressed promptly, it may lead to hydroplaning in rainy weather, longer braking distances in winter, or even tire blowouts - I've learned this the hard way before. I recommend checking every 5,000 km or during seasonal changes, while also adjusting tire pressure for peace of mind and cost savings.
As a car enthusiast, I love tinkering with car parts in my spare time, and checking tire wear indicators is a piece of cake. The wear indicators are usually located at the bottom of the grooves and feel like fixed rubber strips. The method is simple: find a well-lit area, let the car cool down for ten minutes (never check hot tires), walk around the tire, and see if the wear indicators are flush with the tread surface. If they're level, it's time to replace your tires immediately! This not only prevents accidents but also improves fuel efficiency; worn tires increase rolling resistance, burning an extra half liter of fuel every 100 kilometers. Here's a tip: check them during tire rotation for higher efficiency and to ensure all tires are safe.
