What is the Bridgestone tire wear indicator?

When the tire tread is nearly worn out, meaning the remaining tread depth is below 1.6mm, the tire's grip becomes extremely poor—especially during rain or snow. The shallower tread pattern leads to inadequate water drainage, creating a thin film of water between the road and the tire, which can cause the vehicle to lose traction and potentially lead to loss of control. Additionally, the tire's slip increases significantly, dramatically extending braking distances. This not only worsens the vehicle's handling stability but also increases the risk of traffic accidents. National Standard: According to China's national standards, the wear limit for radial tires used in passenger cars is 1.6mm, while for trucks and buses, it is 2.0mm. Tire manufacturers are required to install wear indicators on tires as a mandatory measure. When the tread wears down to these limits, the wear indicator should become visible, alerting drivers to replace the tires promptly. Tire Wear Indicator: This is a marker indicating that the tire tread has reached its wear limit. It appears as a small raised block located at the base of the tread grooves, slightly elevated by 1.6mm above the groove bottom.
