Forklift tires are very important to the equipment.

In case of wear and other problems, they should be handled in a timely manner. Otherwise, the entire equipment may easily become unusable.

Forklift truck tires have an appropriate tire pressure value. When the tire pressure is lower than the standard value, the radial deformation of the tire increases, causing excessive deflection on both sides, so that the two 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 tire 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’s cord layer and the tire and the ground, increase the heat generated by friction, sharply increase the tire temperature, reduce the tensile strength of the rubber, loosen the cord and partially delaminate, and cause tire burst when encountering obstacles and being impacted.

Uneven pressure on the tread causes severe wear on the shoulder, resulting in a “bridge effect”. The tread is dentate or wavy. The concave part of the tire pattern is easy to be embedded into the road nails and stones, causing mechanical damage. The tire rolling resistance increases, and the fuel consumption increases.

When the tire pressure is higher than the standard value, the middle of the tire crown will be grounded, the contact area between the tire and the road will be reduced, the load on the unit area will be increased, and the wear in the middle of the tire crown will be increased. The tire cord is overstretched, the tire cord stress increases, and the tire cord fatigue process accelerates, causing the cord to break, resulting in early tire burst.

Under a certain load tire pressure, when the vehicle speed increases, the tire deformation frequency, carcass vibration, and the circumferential and lateral distortion of the tire (forming a static wave) will increase. The heat generated by friction in a unit time will increase, and the working performance of the tire will decline, even the curtain layer will break and the tread will peel off, accelerating tire wear and damage.

When the tire is corroded by grease, acid and alkali substances and subjected to high temperature for a long time, the physical and chemical properties of the tire will change, the load carrying capacity will be greatly reduced, and the tire is also easy to burst in use. In addition, the tire corroded by oil will suffer from block peeling of air sealing layer, small area rubber falling off at the tire opening, and tire cord separation from the rubber. Because the patch cannot be compatible with the oil filled rubber, even if the damage wound of the tire is small, the possibility of repair is lost.
