How to Determine Tire Wear Indicators?

Determining tire wear indicators: On the sidewall of the tire, there is a small triangular pattern every 60 degrees, which serves as an indicator mark. By following this triangle with your hand towards the tread, you will generally find two grooves on the tire tread. Inside these grooves, you can feel a horizontal line (which is also visible upon close inspection). This is the tire wear indicator. When the raised part of the tread wears down to this line, the tire should be discarded. Below are additional details: 1. If the remaining groove depth of the tire tread reaches or falls below 1.6 mm (there is an indicator mark inside the longitudinal straight groove of the tire tread showing this depth), the tire must be replaced because its water drainage capability is significantly reduced, making driving on wet surfaces more dangerous. 2. National standards stipulate that the wear limit for radial tires used in passenger cars is 1.6 mm, while for trucks and buses, it is 2.0 mm. Tire manufacturers are required to install wear indicators on tires according to these standards. When the tread wear reaches the specified limit, the wear indicator should display to remind drivers to replace the tire promptly.

As a seasoned driver with years of experience, let me share some insights. The key to determining tire safety lies in locating the small raised bar within the tread grooves, known as the wear indicator. You should regularly park your car on level ground, squat down, and carefully inspect with your eyes or feel with your hands: if the tire surface has worn down to the height of this raised bar, approximately 1.6 millimeters, it means the tire has reached its replacement point and should no longer be used. Personally, I make it a habit to check every 5,000 kilometers or during car washes to avoid oversight. Tire wear not only affects braking performance but also increases the risk of skidding and accidents in rainy conditions—safety should never be taken lightly. Additionally, monitoring tire pressure and overall cracks can help extend tire life. In short, developing this habit can save you both hassle and money, as the cost of an accident is far too high.

As a safety-conscious family car user, I always aim to minimize risks. Judging tire wear indicators is actually quite simple: each tire's tread grooves have specially designed raised markers. If the tread wears down to these markers, it's time to replace the tires. I spend a few minutes each month crouching beside my car to feel these markers with my fingers - if they become flush with the tread, that's the warning sign. Don't underestimate this; worn tires increase braking distance and become especially dangerous on wet roads. I've seen a friend's car roll over due to this. Remember, safety isn't just about replacing tires - you should also regularly check tire pressure to avoid deformation or premature wear. Good habits start with small details to ensure safe travels.

As a new driver who's just hit the road, here's a little trick: To check the safety line, look for the raised bands in the tire grooves. If they're worn smooth when you touch them, it's time to replace the tires. I often use a coin to test the tread depth—if it's not deep enough, it's dangerous. This helps prevent skidding and gives you more confidence when driving in the rain. Be sure to check regularly and don't slack off.
