How to Choose the Load Range that’s Optimal for Your Agriculture Tires

So, no surprise, determining the load range that is optimal for your agricultural tires is important for several reasons. First, it will impact the ability of your farm equipment to carry heavy loads while maintaining stability and traction, which can help increase overall productivity and efficiency on a daily basis. Second, proper load range enhances the stability of utility tractors, forklifts, harvesters and other farm implements, which is an important factor in limiting blowouts and overall safety. And finally, selecting the proper load range is good for the longevity of your farm machinery by helping ensure your tires last longer, which saves you money in the long run. The ag tires load range must be sufficient to carry the weight of the equipment and the rider, if any, in order for you to avoid blowouts, accidents and headaches. The tire experts at Treadworld are here to help you with the ins and outs of load ranges—also known as ply ratings—to help maximize your efficiency and your results.

How Does Ply Rating of Tires Factor into the Load Range?

The ply rating of farm tires specifically refers to the number of layers, or plies, that make up the tire’s internal structure. In general, a tire with a higher ply rating will be stronger and more durable than a tire with a lower ply rating. Historically, the number of plies in a tire was an important indicator of its strength and durability, but modern tire technology has allowed for tires with fewer plies to provide the same level of performance as tires with more plies. In fact, many modern trailer tires do not even list the ply rating on the tire’s sidewall. Here at Treadworld, we list the details for each tire under the heading “PLY RATING / LOAD RANGE” so there’s no confusion.

So, What Exactly Is the Ply Rating / Load Range of Farm Tires?

The ply rating/load range of an agriculture tire is an indication of the tire’s strength and durability, at a given tire pressure, leading to its maximum load capacity. A tire with a higher ply rating or load range will generally be able to handle a heavier load than a tire with a lower ply rating or load range, but the tire’s load capacity also depends on other factors such as the size and design of the tire, as well as the intended use and the weight of the equipment it is designed to support. For example, ply rating/load range requirements for tires for tractors, harvesters and combines—which comprise heavier loads—are going to be higher than the ply rating/load range requirements for planters, seeders, cultivators and tillers, which typically require lower load range tires.

What Ply Rating/Load Range Numbers/Letters Mean

As noted, we provide you with the Ply Rating/Load Range measurements, at the optimal air pressure (PSI, pounds per square inch), for every agricultural tire you’re looking for, as well as how that measurement translates into load capacity for each tire size. Still, generally, it’s good to know how various ply rating/load ranges relate to each other.

For example, a tire with a ply rating/load range of 4/B is typically designed for lighter loads and equipment, and has less strength and a lower load-carrying capacity than tires with higher ply ratings/load ranges. A tire with a ply rating/load range of 6/C is designed for moderate loads and equipment, and has more strength and a higher load-carrying capacity than a tire with a 4/B rating. Further, a tire with a ply rating/load range of 8 is designed for heavier loads and equipment, and a tire with a ply rating/load range of 12 is designed for very heavy loads and equipment, and has the most strength and the highest load-carrying capacity of these four options.

Keep in mind that a tire with a lower rating may not be strong enough to support the weight and stress of heavy loads, while a tire with a higher rating may be more expensive than is necessary if it’s used with lighter equipment.

How to Determine the Optimal Load Range Required for Your Agricultural Tires

Whether you’re selecting tires for forklifts, loaders, backhoes, sprayers, manure spreaders, bailers or any other agriculture equipment, your ag tires must have a sufficient tire load range capacity. The first step to determining the maximum load capacity required for your tires is to identify the weight of your equipment, including any attachments, plus the weight of any load it will be carrying. It’s also a good idea to check the equipment manufacturer’s recommendations, in the owner’s manual or on-line. And, you’ll want to consider the terrain and conditions in which your equipment will be operating, which can impact the load range required for your tires. For example, if your equipment will be used in wet or muddy conditions, a higher load range may be required to provide the necessary traction and support.
