What is the wear limit for car tires?
1 Answers
Generally, the wear indicator height for passenger car tires is 1.6 millimeters (this height is also the legally mandated minimum tread groove depth), while for heavy-duty tires, the wear indicator height is 2.4 millimeters. The maintenance methods for tires are as follows: Perform wheel alignment and tire rotation: Conduct a wheel alignment and tire rotation every 10,000 kilometers traveled. Regularly check tire pressure: Tire maintenance also includes periodic pressure checks. Tires with pressure exceeding the specified range will significantly reduce their service life, while tires with pressure below the specified range can lead to poor braking performance, difficulty in steering, or heavy steering, and will also shorten the tire's lifespan. Always pay attention to the wear indicators on tires: The wear indicators are located in the main tread grooves of the tire and appear as trapezoidal rubber protrusions. When the tire tread wears down to the level of the wear indicators, the tire must be replaced. During the rainy season, to prevent the vehicle from slipping on wet roads, the tread depth must be maintained at least 3mm. Regularly inspect tire condition: Frequently check tires for any bulges, cracks, cuts, punctures, valve rubber aging, or abnormal tire wear. Pay special attention to the wear on the tire tread and edges.
