Industrial solid tyres require appropriate tyre pressure

Industrial solid tyres require appropriate tyre pressure
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 increases, and both sides produce excessive deflection, so that both sides of the tire crown are grounded, the inner wall of the tire side is compressed, the outer wall of the tire side is pulled, and the cord in the tire body produces large deformation and alternating stress.
Periodic compression deformation will lead to fatigue damage of the return cord, increase the relative slip between the tire cord and the tire and the ground, increase the heat generated by friction, and sharply increase the tire temperature, which will reduce the tensile strength of the rubber, loose the cord and partial delamination, and cause tire blowout when encountering obstacles and being impacted.

The uneven pressure on the tread causes serious wear on the shoulder of the tire, resulting in a "bridge effect", and the tread is toothed or wavy. The concave part of the tire pattern is easily embedded into the nails and stones of the road, causing mechanical damage. The rolling resistance of the carcass increases, and the fuel consumption increases. The test shows 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 is grounded, the contact area between the tire and the road is reduced, the load per unit area is increased, and the wear in the middle of the tire crown is intensified. The tire cord is overstretched, the tire body cord stress increases, and the cord fatigue process accelerates, causing the cord to break, resulting in early tire burst.
