The tire pressure mark is usually located on the side of the tire. The position of the tire pressure mark generally indicates the maximum load-bearing capacity of a single tire and the maximum safe inflation pressure of the tire under normal circumstances. For example, if the tire is marked MAX. Press .350kPa on the side, which means the maximum safe inflation pressure of the tire is 350kPa under normal circumstances; the maximum load capacity of 615KG means that the maximum load capacity of a single tire is 615kg. The tire pressure is generally within the normal range of 2.3-2.5 bar. However, the standard tire pressure will be different due to different models, and the tire pressure will also be affected by factors such as seasonal temperature, driving road conditions, and vehicle weight. Therefore, the normal range of tire pressure is uncertain. Standard tire pressures can generally be found in the car owner's manual, on the label next to the cab door (near the B-pillar), on the drawer next to the driver's seat, or on the small door of the fuel tank cap. However, according to the regulations and requirements of the international GBT2978-2008 standard, standard tires are 2.4-2.5bar, reinforced tires are 2.8-2.9bar, and the maximum air pressure must not be greater than 3.5bar. This is only a reference value for tire pressure. The specific situation depends on the season and Adjust according to road conditions, vehicle weight, and tire condition. In addition to tire pressure, tire identification also includes production number, manufacturer's trademark, size specifications, grade, etc. The carcass material is represented by Chinese Pinyin, cotton cord is represented by M; rayon cord fabric is represented by R; steel cord is represented by G, and steel wire radial tire is represented by ZG.
