When selecting between bias and radial tires for heavy tractors during deep tillage operations, it’s important to understand the key structural differences. Bias tires are constructed with multiple nylon plies layered diagonally, while radial tires feature a single ply of steel belts running radially from bead to bead, often combined with flexible sidewalls.
For applications requiring speeds exceeding 50 km/h, carrying extra-heavy loads, or achieving a smoother and more stable ride, radial tires are the superior choice. They provide better traction, reduced soil compaction, improved fuel efficiency, and enhanced operator comfort due to their flexible construction. The main consideration is that radial tires typically come at a higher price point.
If your tractor is used for regular operations without extreme demands, bias-ply agricultural tires remain a reliable and cost-effective solution. They offer robust performance, good load-bearing capacity, and are generally available at a competitive price with faster delivery times.
Ultimately, the choice depends on your specific operational needs and budget considerations.
For optimal storage of farm tires, which typically operate under lighter load conditions, it is recommended to store them either inflated with tubes or mounted on wheels. This helps maintain their shape and prevents damage. Additionally, tires should always be stored in a warehouse or indoor facility, shielded from direct sunlight to avoid UV degradation and premature aging.
The term “ply rating” (PR) refers to the strength and load-carrying capacity of bias-ply tires. For instance, a 12PR tire is stronger and can support heavier loads than a 10PR tire.Originally, the ply rating indicated the number of cotton layers used in the tire’s construction. Today, it represents the tire’s equivalent strength rather than the actual number of plies. For example, a 12PR tire made with modern materials such as nylon has the same strength as a tire made with 12 cotton plies.
