How much mileage does a car tyre need to be replaced?
Comprehensive traffic 3-5 km. Asphalt smooth road 50 thousand kilometers, sand rough road 30 thousand kilometers. When more than 30 thousand kilometers, the tread friction coefficient is less than 50. If the pavement is wet and wet, the extrusion and drainage function of tire tread will decrease or lose, the friction coefficient is less than 15, and the sand road surface will burst easily.
Tread groove less than 1.6MM, should be replaced tires. Tread groove wear indicator shows that the groove depth is exposed, only less than 1.6 mm, the tire wear indicator is raised in the ditch, if you use the remaining groove depth below 1.6 mm tires will appear wet traction and braking force will suddenly lose, and the possibility of snow traction nothing.
The replacement of automobile tires, on the one hand, depends on mileage and service life. On the one hand, it also depends on the actual use. The following indicators for tire change, specific reference.
