Agricultural tractor drive tires come in various models, primarily categorized by their intended use, tread pattern, and suitable operating environment. Below are some common models and their characteristics:

1. R-Series Tires

R-1: General purpose, suitable for dryland operations and short-distance field transport. This tire performs well on a variety of terrains and is a versatile choice for agricultural operations.

R-2: Sunshade and paddy field type, designed specifically for field operations in moist, muddy conditions. Its tread depth is at least twice that of the R-1, providing excellent traction and self-cleaning properties in wet terrain.

R-3: Buoyancy type, suitable for soft, sandy soil operations. This tire features a block or button-shaped tread pattern, reducing ground damage while providing good buoyancy.

R-4: Industrial type, suitable for agricultural engineering operations. This tire performs exceptionally well on hard surfaces, meeting the specific needs of agricultural engineering operations.

2. Other Specific Purpose Tires

PR-1: Paddy field type, designed specifically for paddy field operations. These tires feature high-tread patterns and water-resistant materials, providing excellent stability and durability in paddy field environments.

CR-1: Suitable for inter-row cultivation. The tread pattern design of this tire helps reduce soil compaction, improving the efficiency of inter-row cultivation.

3. Supplementary Model Classification by Tire Structure

Bias-ply tires: Such as 14.9-30, 16.9-30, etc. These tires have their cords arranged diagonally, providing a degree of flexibility and durability, suitable for medium-speed driving on ordinary roads.

Radial tires: Such as 420/85R34, 16.9R34, etc. These tires have their carcass cords arranged radially, offering excellent handling and stability, better meeting the needs of agricultural machinery under various operating conditions.
