1.Under certain load and driving conditions, the tires of the forklift have a suitable tire pressure. When the tire pressure is lower than the standard value, the radial deformation of the tire will increase, and excessive deflection will occur on both sides, so that both sides of the tire crown Grounding, the inner wall of the sidewall is compressed, and the outer wall of the sidewall is stretched, and the cords in the carcass produce greater deformation and alternating stress. The uneven pressure on the tread causes serious wear on the shoulders, resulting in a “bridge effect”, and the tread is toothed or wavy. Tire tread recesses are easy to be embedded in road nails and stones, causing mechanical damage.
2. Under a certain load and tire pressure, the vehicle speed increases, the deformation frequency of the tire, the vibration of the carcass and the tire circumferential and lateral distortion (forming a static wave) will increase, and the heat generated by friction per unit time will increase. The working performance of the tire decreases, and even the ply rupture and tread peeling phenomenon occur, which accelerates the wear and destruction of the tire.
3. High temperature will reduce the tearing strength, elongation and hardness of the rubber, reduce the adhesion strength between the rubber and the cord, and accelerate the aging of the rubber. For tires under high temperature, especially aging tires, when side-slip or roll over obstacles occur, it is easy to tear the crown pattern. Due to the aging of the sidewall rubber, cracks and severe deformation of the sidewall result in the separation of the carcass cord from the rubber. Once the tire is locally exposed to a sudden load, it is likely to cause a puncture.
4. Due to the different load distribution of the front and rear axles, the different working characteristics of the driving wheels and steering wheels, and the difference in road conditions, the wear conditions of each tire are inconsistent. If the two sides of the same axle are not replaced with the same factory, the same size, structure, level and Patterned tires will accelerate tire wear.
5. Road conditions also have a great influence on the service life of the tire, which affects the friction between the tire and the ground and the dynamic load on the tire.
