1.The tires importand parts for vehicles to transmit power ,surport load and provide road friction .
2.The tire is composed of a tire body,a tire curtain and a tread layer .The tire body is the main skeleton of the tire,and the tire curtain is the reinforced tire .
The layered material of the body ,and the tread layer is the part that touches the ground .
3.The size of the tire is usually expressed as "tire width/flatness ratio R radial structure code .Wheel net diameter " .For example 225/45R17 represents a tire width of 225mm and a latness ratio of 45%.the diameter of the wheel steel is 17 inches .
4.The rim diameter of the tire is closely related to the braking ,suspension steering and stablity of the vehicle.The appropriate size can improve the performance and sately of the vehicle .
5.The carrying capacity of a tire depends on the material and structure of its tire body and tire curtain .Generally ,The speed level and load index of the tire are marked by the load .
6.When driving at high speed , the temperature of the tire will rise ,so the tire needs to have good heat dissipation performance .It will have a negative impact on tire life and satety .
7.The year effect of tires refers to the contact of tires with air and sunlight .The longer the time,the faster the tires age .
8.The pattern design of the tire provides grip while also affecting the noise ,comfort and fuel of the tire .
9.New tires usually have a layer of oil film ,which can play a protective role .They need to be removed and tried before use .
10.The need to be checked regularly for air pressure,damage,bulge and other conditions .To ensure satety and service life .
11.The air pressure of car tires is generally 2.0-2.5 bar,and the storage of large vehicles is asjusted according to the tire specifications .
12.The degree of wear of the tire can be measured by the pattern depth determine the life of the tire and more change the timing .
13.Incorrect rotation direction will affect the life and performance of the tire,and the tires will be marked with arrows indicating the direction of rotation head .
14.The use of tires of different brands and models may affect driving stability and safety .
