Tire is an important component of the agricultural vehicle's walking system and directly affects the performance of the vehicle's various uses. Attention should be paid to the following points when using it: (1) The normal air pressure of the tire is often maintained, but in order to make the tire different Under the conditions, it can be better used and extended its service life. In the area where road arches are relatively large, the outside tire pressure of the rear wheels can be increased by 0.02-0.03 MPa compared with the standard air pressure. In addition, when driving on hard roads, the air pressure may be slightly higher; when encountering soft roads, the air pressure may be slightly lower. (2) When the vehicle starts and brakes, the operation of the clutch and brake must be well coordinated. Try to make the start as smooth as possible, stop slowly, and avoid emergency braking. At the same time try to avoid turning small bends to reduce tire wear. (3) Do not overload the loaded cargo. Overloading will increase the deformation of the tire, increase the relative slip with the ground, and increase the wear. (4) Correctly disassemble the tire. Use special tools when installing the tires. Do not hit the tires and steel rings with a heavy hammer. When loading, the inner and outer tires and pads should be clean and dry, and a layer of talcum powder should be evenly coated on the inner wall of the tire, the inner tube and the surface of the tire. Rim, ring, and lock ring should be intact. When installing the tire with the arrow indicating the direction, the arrow must be forward. When the twins are installed together, the small-diameter tires are installed in the internal gear and the two-tire valve is 180. (5) In order to make the tire wear evenly, it should be combined with the vehicle maintenance cycle for tire replacement. The transposition should use two methods of “cyclic transposition†and “crossover transpositionâ€, and exchange the tire pressure to adjust the tire position. (6) Pay attention to the storage and storage of tires. Tires should be stored indoors, in a dry and unventilated place. Avoid open storage and keep them away from fire. Do not store them in the same room as acids, alkalis, paints and organic solvents to prevent them from corroding. Tires should be erected on the wooden stand with the tread upright and change its support point periodically.
