The normal tire pressure range for agricultural tractors is usually between 2.5 and 3.5 kg, and the specific values will vary depending on the season, tire type and usage scenario. In winter, the air pressure of the front wheels is recommended to be maintained at 2.5 to 2.7 kg, and the rear wheels are 2.7 kg; in summer, the air pressure of the front wheels can be adjusted to 2.3 kg and the rear wheels are 2.5 kg. In addition, the standard air pressure of tractor tires during tillage operations is usually between 200 and 300 kPa, and in transportation, it should be adjusted to 250 to 300 kPa. The air pressure of the drive wheels during tillage is recommended to be 80 to 120 kPa, and it needs to be increased to 140 to 190 kPa during transportation.
Factors that affect tire pressure include seasonal changes, tire type and usage scenarios. In winter, when the temperature is low, the tire pressure should be appropriately increased to cope with the low temperature environment; in summer, when the temperature is high, the tire pressure should be appropriately reduced to prevent tire blowouts. Different types of tractors (such as general-purpose, row-cultivation, etc.) may also have different tire pressure requirements, so these factors should be considered comprehensively when choosing tire pressure.
