What are the Common Specifications of Agricultural Tires
10.16.2026

The most mainstream and widely used agricultural tire specifications in the domestic agricultural machinery market can be divided into five categories according to the type of suitable agricultural machinery, covering the full range of needs from micro tillage machines to high-power tractors:

1. Common specifications for small micro tillage machines/hand-held tractors

This type of specification is suitable for low-power lightweight agricultural machinery and is the foundation for operating small plots of orchards and vegetable gardens

4.00-8, 5.00-12, 6.00-12: Micro tillage machines and field management machines come standard with lightweight tire bodies that can carry up to 500kg per tire, and are affordable.

6.50-16, 7.00-16: Suitable for small hand-held tractors and agricultural tricycles, catering to the needs of lightweight farmland and short distance transportation.

2. Mainstream specifications for medium and small horsepower tractors

This type is the highest specification for dry field operations in China, suitable for conventional tractors with 20-80 horsepower:

7.50-16, 8.3-20: Classic front steering wheel of 30-40 horsepower tractor, flexible steering, suitable for light tillage operations in northern wheat corn rotation areas.

9.5-20 and 11.2-24:50 horsepower tractors come standard with drive wheels, featuring a herringbone pattern for strong traction and balancing farmland and road transportation. It is the most popular specification in Shandong, Henan, and other regions.

12.4-28, 14.9-24: Commonly used drive tires for 60-70 horsepower tractors, with a maximum load capacity of 2 tons or more at the 12PR level, meeting the requirements of conventional deep plowing operations.

3. High horsepower heavy-duty tractor/harvester specifications

This type of machinery is suitable for high horsepower agricultural machinery with over 80 horsepower, has strong load-bearing capacity, and is suitable for heavy-duty operations in contiguous fields

14.9-30, 16.9-30: mainstream drive tires for 100 horsepower tractors, with a cross-sectional width of 430mm and a maximum load capacity of 2.73 tons under standard air pressure of 0.24 MPa.

18.4-38, 20.8-38: Standard configuration for four-wheel drive tractors with over 120 horsepower and large corn harvesters, with strong tire body rigidity, suitable for heavy-duty traction scenarios on black soil in Northeast China.

4. High flower specifications for paddy fields

This type of pattern has a depth far exceeding that of ordinary dry field tires, and has strong anti sinking and self-cleaning abilities, making it a must-have for rice field operations in the south:

650-16, 750-16: Suitable for small paddy field tractors, with a pattern depth twice that of ordinary dry field tires, to avoid sinking vehicles on deep muddy ground.

9.5-32, 11-32, 12.4-48: Specially designed for medium-sized paddy field tractors, with high mud discharge efficiency and low risk of slipping even when operating in muddy terrain for a long time.

5. Specifications for high-end high-power radial agricultural tires

This type is the mainstream upgraded version of imported high-end agricultural machinery with over 150 horsepower in recent years. It has a large grounding area and can significantly reduce soil compaction

380/85R24, 520/85R38: Classic matching of front and rear wheels for high horsepower tractors, with low rolling resistance and a wear life that is more than 30% longer than that of diagonal tires.

540/70R24, 650/65R38: Specialized for large combine harvesters, with high load-bearing design suitable for high-frequency heavy load transfer during cross regional operations.
