How to Determine Tire Wear Indicators?

[AveryLee]

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.
