The use of tires should generally not exceed 3 years and the mileage should not exceed 60000 kilometers. Although slightly exceeding the age and mileage does not affect the overall situation, the low temperature in winter and the rain in summer can make the wet grip and dry handling of the tires "difficult". Pay more attention to the sidewall: As the tire rubber gradually ages, deep lines will appear on the sidewall of the tire. But as long as the tire sidewall is not impacted and the cord is not broken, it can continue to be used. The triangular mark on the sidewall of the tire can help the owner find a protrusion in the groove of the tire crown, which can determine the actual wear limit of the tire, which should be greater than 1.6 millimeters.

Correctly selecting suitable tires

Car tires: can be divided into ordinary sedan tires, wagon tires, and sport tires. Ordinary car tires prioritize comfort, reduce energy consumption, and improve durability; Touring car tires tend to increase the load-bearing capacity and durability of the tires; Sports tires place more emphasis on handling performance. Off road tires: can be divided into high-speed tires, mud tires, and combination tires. High speed tires are suitable for driving on paved roads, but their sidewall support is slightly weaker; Mud tires have deeper patterns and are suitable for driving on unpaved roads, but the vehicle's fuel consumption may be slightly higher; Integrated tires have the advantages of both, while eliminating their disadvantages, but both have made concessions.
