After we have been in contact with the forklift industry for a long time, if we operate the internal combustion forklift incorrectly, after a period of use, the tires of the internal combustion forklift will wear out. Do you know the reason why the internal combustion forklift tires wear too fast? As a professional forklift manufacturer, Hifoune Forklift will introduce to you the reasons why the tires of internal combustion vehicles wear fast enough.
low tire pressure
Forklift tire pressure Under certain load and driving conditions, forklift tires have appropriate tire pressure. When the tire pressure is lower than the standard value, the radial deformation of the tire increases, and there is excessive deflection on both sides, resulting in grounding on both sides of the tire crown, the inner wall of the sidewall is compressed, the outer sidewall of the sidewall is pulled, and the carcass is greatly deformed and alternated. The periodic compression deformation of the stress cord will accelerate the fatigue damage of the cord, increase the relative slip between the tire ply and the tire and the ground, increase the heat generated by friction, increase the temperature of the tire sharply, reduce the tensile strength of the rubber, and reduce the tensile strength of the rubber. Lines, loose and partially delaminated, tire blowout when encountering obstacles. The uneven force on the tread causes serious wear on the shoulders, resulting in a "bridge effect", and the tread is toothed or wavy. The concave portion of the tire tread is easily embedded in the nails and stones of the road, causing mechanical damage. The rolling resistance of the carcass increases and the fuel consumption increases. Tests show that when the tire pressure is 20%-25% lower than the standard value, the fuel consumption will increase by 20%. When the tire pressure is higher than the standard value, the center of the tire crown touches the ground, the contact area between the tire and the road surface decreases, the load per unit area increases, and the wear of the center of the tire crown increases. The tire cord stress is too large, the carcass cord stress increases, and the cord fatigue process accelerates, resulting in the cord pulling and breaking, resulting in early tire blowout.
increasing speed
Under a certain load and tire pressure, with the increase of vehicle speed, the tire deformation frequency, tire carcass vibration, tire circumferential and lateral deformation (forming static waves) will increase, the heat generated by friction per unit time will increase, and the working performance of the tire will increase. It will drop, and even the ply cracking and tread peeling will occur, accelerating tire wear and damage.
tire overload
Under a certain tire pressure, the overload of the tire increases its bending deformation, and the stress of the cord and cord increases, which easily leads to the rupture and relaxation of the sidewall cord, and the delamination of the cord. The stress on the tire cord will exceed the design allowable stress and tire ground contact pressure, resulting in increased heat, increased tire temperature, and reduced load-carrying capacity. At the same time, the shoulders wear from contact with the ground, especially when encountering obstacles, and even small stones can cause the crown to burst. Practice has proved that when the tire load exceeds 20%, the mileage will be shortened by 35% when turning and the road surface is uneven; when it exceeds 50%, the mileage will be shortened by 59%; when it is more than once, the mileage will be shortened by more than 80%.
road conditions
Road conditions also have a great impact on the service life of the tire, affecting the friction between the tire and the ground and the dynamic load on the tire.
High temperature environment
High temperature will reduce the breaking strength, elongation and hardness of rubber, reduce the bonding strength of rubber and cord, and accelerate the aging of rubber. For high-temperature tires, especially aged tires, it is easy to tear the crown pattern when slipping or rolling over obstacles. Cracks caused by aging of the sidewall rubber and severe deformation of the sidewall lead to separation of the carcass ply cords and rubber. Once the tire encounters a sudden load locally, it is likely to burst. Corrosion of grease and acid and alkali substances
When the tire is corroded by grease, acid and alkali substances, and exposed to high temperature for a long time, the physical and chemical properties of the tire will change, the bearing capacity will be greatly reduced, and the tire will easily burst during use. In addition, tires corroded by oil will appear blocky peeling of the sealing layer, small rubber peeling at the tire opening, and separation of the carcass cord from the rubber. Because the patch is not compatible with oil-containing rubber, even if the damage to the tire is small, the possibility of repair is lost.
uneven load

Due to the different loads distributed by the front and rear axles, the working characteristics of the driving wheels and the steering wheels are different, and the road conditions are different, and the wear conditions of each tire are inconsistent. If the tires of the same factory, the same size, the same structure, the same grade and the same pattern are not replaced on both sides of the same axle, the tire wear will be accelerated. In use, if you do not pay attention to reasonable collocation and regular rotation, it will lead to uneven loading of the tires, and will also accelerate tire wear.
