How Can Radial Trailer Tyres Improve Load Capacity?

Sat, 3 Sep 2022 | PRODUCTS


The days of slowly hauling heavy loads from field to farm are long gone, with modern farming requiring trailers and associated tyre equipment that can keep pace with the capacity – in terms of both speed and power – of today’s tractors. When you are next searching trailer tyre price lists and looking for ‘trailer tyres for sale’ or ‘trailer tyres near me’, consider the benefits modern radial trailer tyre design can bring to helping you get the maximum from your trailer’s capabilities.

From their inception, pneumatic tyres for all types of vehicle were designed and manufactured on a cross-ply or bias format, with interlocking cords layered across each other at a 45-degree angle, as the basis for the tyre’s outer rubber carcase. This design gives the tyre high sidewall rigidity which, in turn, ensures high strength, but the downside is that the carcase is highly inflexible. Although this characteristic helps protect the tyre sidewalls against damage, it also means a firm ride and an inflexible footprint.

Because radial tyres are designed with their base cords layered around the circumference of the tyre carcase, they possess more flexible sidewalls. This means that, compared with a cross-ply tyre operating at the same pressure, the tyre footprint is wider and longer. As a result, the load of the machine to which the tyres are fitted is more widely distributed. For an agricultural trailer, with tyres of a relatively small diameter, this is particularly important. Your tractor may be equipped with modern radial tyres offering a broad, long footprint, but the benefits of this to the soil of the fields on which you may be working is lost if the trailer it is hauling behind it is fitted with inflexible cross-ply trailer tyres with a small contact patch and a resulting high ground press imposition that compacts your soil.

For the same pressure level, radial tyres offer greater load capacities than cross-ply/bias tyres because of these design attributes. With trailer tyres, this means you can maximise the load capacity of your trailer while spreading the load over the maximum possible ground contact area, to ensure the minimum possible soil compaction and crop damage.

Radial trailer tyres may cost a little more than cross-ply trailer tyres of the same size, but if you study the manufacturer’s design specifications, they may also offer a number of other advantages. For example, the CEAT Specialty Floatmax RT design incorporates a flatter crown width that helps further to deliver a larger footprint and lower compaction. The pattern of interconnected grooves aids self-cleaning to minimise carriage of mud onto the road, where robust centre blocks reduce road noise and ensure smooth running. In the field, meanwhile, the rounded shoulders help minimise soil and crop damage, while steel belted construction minimises puncture risk.

For loose soil surfaces such as those found during root crop harvest, Floatmax FT radial trailer tyres are a further option. These blend radial design with directional lugs that aid traction, while a wider and flatter crown maximises flotation, and a robust centre block enhances ride on the road.

With radial trailer tyres you can therefore spread the load of your trailer across a greater contact area, helping maximise load capacity but without compromising on compaction in the field. When next searching trailer tyre price lists and looking for ‘trailer tyres for sale’ or ‘trailer tyres near me’, investing a little extra in radial trailer tyres can clearly bring benefits to your business by helping you get the maximum from your trailer’s capabilities.
