Cropmaster R-1


  • Enhanced controllability
  • Upgraded durability
  • Field friendly performance


The Cropmaster R-1 is an all season tire manufactured for agricultural tractors.

The tire features a directional lug placement. The tread design upgrades the steering responsiveness and the driving stability as it ensures the model’s constant surface contact throughout its performance. This boosts the steering response time and accuracy to the driver’s commands, while the structure is stabilized against the driving pressure affecting the model. This combination ensures the driver’s full control over the vehicle on various terrain surface conditions.

The strengthened internal structure manages to boost the load capacity. The reinforced internal structure maintains the ideal tire shape under the load and driving pressure affecting the tire while the tires are in motion. This construction prevents the tire’s deformation under the load and driving pressure affecting the model, increasing its load carrying and withstanding ability. As the tire does not deform during its heavy-duty performance, the tire provides a safer driving experience.

The R-1 promotes a field friendly performance. The directional tread design’s optimal soft traction improves the tire’s high flotation ability. The model’s better flotation prevents the tire from harming the terrain and field surface. It prevents pressure from accumulating on one area and enables the tire to perform without ruining the soil quality with its tread. The model’s wider footprint, further improves the soft traction, guaranteeing a secure off-road performing capability.

This specific tire model features a BIASED ply construction.

There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.
