Which Tyre to Choose – Radial vs Bias Tractor Tyres?

Radial tyres have proven to have many benefits, such as more traction and less soil compaction. Despite these advantages, the “Old-fashioned” bias ply tyres continue to roll strong in the agricultural tyre market. 

Bias Tyres – Design as a Single Unit

The bias tyre design has been in use beginning sometime around the 1930s. This design consists of multiple rubber plies placed diagonally bead to bead to form a pattern. Due to this way of construction, the sidewall and tread act as a single unit in a Bias tyre, resulting in a stronger and stiffer sidewall capable of fending off any damage from rocks and stumps. This stiffness also makes it better for use in hilly terrain as it offers excellent stability.

However, the stiff construction of Vredestein Tractor Tyres may lead the operator to have a punishing ride. Because of the single unit design, when the sidewall of the bias tyre flexes. The treads do the same, causing tread deformation, which can lead to a distorted or smaller footprint. It could reduce traction, increase wheel slippage, and could lead to additional compaction within your fields.

Radial Tyres – Improved Flexibility Using a Two-part Design

A radial tyre is identifiable using the ‘R’ marked on the tyre sidewall. Radial tyres, which were first invented in 1946, have become the go-to tyres for carrying heavy loads and maximizing traction performance in the field. With the cord plies arranged perpendicular to the travel direction, and with the under-tread area being wrapped around the tyre circumference using radial belts made with fabric or steel, the tyre sidewall flex can be contained without being transferred to the treads, which otherwise could have lead to even more wear. 

The construction followed in a radial tyre design allows for a more uniform, and larger tyre footprint, basically resulting in less compaction and wheel slippage, and more traction. You are essentially getting more output for each revolution of the engine when radial tyres are used in your tractor. Along with this, you are also preventing soil damage from compaction which usually reduces the yield.

Which Tyre Should I Choose?

Ceat Tractor Tyres are like having newer technology in your vehicle: new cutting-edge technology comes at a cost. Dependable and durable bias tyres are good for routine field tasks like chopping corn stalks, powering augers, or cutting hay. For such uses, a quality tyre is needed but the increased efficiency that is available in a radial tyre might not be the best utilized, especially when the price of purchase is factored into the equation.

On the contrary, the added investment to purchase a radial tyre would likely pay off when you are using the tractor for heavy field work like carting grain, harvesting, planting, and tillage. Every year, manufacturers are trying to expand the radial category by introducing more and more IV/VF tyres, which are tyre designs that achieve higher performance while allowing for more flexing of the sidewalls. These innovative tyres can handle more loads at lower pressures to achieve a larger footprint.

  1. Thank you for an additional great post. Exactly where else could anybody get that kind of facts in this kind of a ideal way of writing? I have a presentation next week, and I’m around the appear for this kind of data.
