PR-1
- 10 sizes
- Bias Agricultural
PR-1 is a bias agricultural tyre designed specifically for paddy field operations. It is built to maintain traction and stability in soft, wet, and muddy conditions common in rice paddies. The tyre's tread pattern and construction are suited to low-speed, high-torque work on uneven terrain, with load capacities and inflation pressures tailored to each size.

What PR-1 Is Built For
PR-1 is a bias agricultural tyre designed specifically for paddy field operations. It is built to maintain traction and stability in soft, wet, and muddy conditions common in rice paddies. The tyre's tread pattern and construction are suited to low-speed, high-torque work on uneven terrain, with load capacities and inflation pressures tailored to each size. It is available in ten sizes from 6.50-16 to 16.9-34, with ply ratings of 6, 8, and 10, and tread depths ranging from 60 mm to 90 mm. The tyre is supplied with standard rims matching each size, and is intended for use on tractors and agricultural machinery operating in flooded or soft soil environments.
Manufacturer Feature Claims
- Special for Paddy Field
Key Benefits
- Designed specifically for paddy field conditions with high traction and low ground pressure
- Tread depth up to 90 mm provides long wear in soft, muddy terrain
- Multiple sizes and ply ratings allow matching to different tractor and implement loads
- Inflation pressures and load capacities are specified per size to prevent overloading
- Rim sizes are matched to each tyre to ensure proper fit and stability
Problems It Solves
- Standard tyres lose traction and sink in soft, wet paddy fields due to insufficient tread depth and ground pressure
- Incorrect inflation pressure leads to casing damage or reduced load capacity on uneven terrain
- Multiple tyre types needed for different paddy field sizes and tractor weights increases stock complexity
- Lack of paddy-specific design causes rapid wear and poor performance in flooded conditions
- Mismatched rim sizes cause instability and uneven wear on agricultural machinery
Who It Is For
- Agricultural dealers supplying tyres to rice farmers in Southeast Asia and South Asia
- Fleet operators managing tractors used in paddy field operations
- Importers sourcing tyres for markets with high demand for rice cultivation equipment
- Distributors who need a single supplier for multiple paddy-specific tyre sizes
- Contractors running seasonal paddy field work who require reliable, low-slip tyres
Application Scenarios
- Tractors operating in flooded rice paddies with soft, wet soil and low traction
- Harvesting and transplanting operations where consistent grip is needed on muddy surfaces
- Field work on uneven, waterlogged terrain where standard tyres lose grip and dig in
- Agricultural contractors running multiple machines across different paddy field sizes
- Fleet buyers sourcing tyres for a mixed fleet of tractors used in wet, low-friction environments
Technical Features
- Bias construction with reinforced casing for durability in soft, muddy terrain
- Tread depth from 60 mm to 90 mm designed to resist wear in high-moisture, low-friction conditions
- Tread pattern optimized for grip and self-cleaning in mud and water
- Rim sizes specified per tyre to ensure correct fit and load distribution
- Load and pressure values are provided for each size in the size table, not generalized

Where This Pattern Wins and Where It Does Not
Compared With General-purpose agricultural tyres
PR-1 is designed specifically for paddy fields with deeper tread and optimized grip in mud; general-purpose tyres wear faster and lose traction in flooded conditions
Compared With High-speed radial agricultural tyres
PR-1 is bias construction with lower speed capability; radial tyres are better for high-speed field work but less effective in soft, wet terrain
Compared With Off-road or industrial tyres
PR-1 has a tread pattern and casing designed for soft soil; off-road tyres are built for rock and gravel and perform poorly in mud
Use Guide
- Match the ply rating to the actual axle load of the tractor or implement, not to the maximum available
- Use the inflation pressure listed in the size table for the specific size and load
- Check the rim size against your wheel to ensure correct fit and stability
- Inspect the tread for mud buildup after each paddy cycle to maintain grip and prevent casing damage
- Rotate tyres between positions before uneven wear sets in, especially on machines with one-way work patterns
PR-1 Buying Questions
What is the minimum order quantity?
We load by full container. A 40HQ typically fills at container weight rather than volume, so the practical minimum is one container. Mixed loads across sizes and patterns are accepted.
What is the lead time?
It depends on whether the size is in stock at the plant or has to be produced. We confirm current availability with the plant at the time of quotation.
Which sizes are available?
10 sizes: 6.50-16, 7.50-16, 8.3-20, 8.3-24, 9.5-24, 11.2-24, 11/12.4-28, 14.9-30, 11-32, 16.9-34. Full load, pressure, rim, and dimension data is in the size table.
Can you supply this tyre with a different rim size?
We supply the tyre with the rim size specified in the size table. Custom rim fitment is not available unless the plant can support it, which is not guaranteed.
Is there a warranty?
Yes, one year against manufacturing defect on all tyres supplied. Claims are handled directly by us, not passed back to the plant.
Can you ship a mixed container with other tyre types?
Yes. Most of our customers load one container across several patterns and sizes, which is the main reason to buy through us rather than from a single plant.
What certificate of origin can you provide?
We provide all kinds of Certificate of Origin available, including China, Thailand, and Cambodia, depending on the plant of origin.
