Radial and Bias Tractor Tyres
A radial tractor tyre is designed as a two-part construction allowing the sidewall of the tyre to flex independently of the face or tread area of the tyre.
A bias tractor tyre is designed with a single ply wrapped diagonally from one side of the tire to the other. This means that as the tyre flexes, the face or tread of the tyre deforms leading to faster and more uneven wear. In addition, the overlapped plies form a thick layer that is less flexible and more sensitive to overheating.
Under load the bias tyre flexes more compared to the radial tyre. Due to the flexing, the rolling circumference for bias tractor tyre is different from that of similar size radial tyre. If conversion is done from radial to bias on a 4x4 tractor the coupling, shaft or differential might be affected.

Advantages of a Radial Tractor tyre:
- Better grip and traction withwide tread, reduced slip
- Lower rolling resistance
- Minimised soil compaction
- Maximized life span
- Improved driving comfort with stronger and moreflexible sidewall
- Lower fuel consumption
- Higher load capacity
