Implement Tyres

Implement machinery tyres cover quite a wide range of applications. We class a number of different equipment types under the 'Implement' category. As a rough guide, implement tyres are the types of tyre that are used on farm equipment that is pulled behind tractors. This may include farm trailers, balers, tedders, muck / slurry spreaders and many other types of trailed machines and equipment. 

If you are looking for Implement Machinery Tyres, you have come to the right place. Terrain Tyres has an extensive catalogue of all of the popular makes, models and sizes. We have quality, yet affordable offerings from BKT, GRI, Galaxy and Ozka and also have premium choices such as Vredestein, Trelleborg and Camso. We have tyres for all implement machinery applications in a variety of different patterns, ply ratings and price points. Our Implement Tyre patterns include more aggressive tractive tractor type patterns, Zig-Zag and flotation patterns and also block patterns for use on hard packed surfaces. We also stock tyres with reinforced sidewalls and heavy ply ratings to offer the best durability and puncture resistance, minimising down time of farm equipment and machinery. If you have any questions relating to your implement tyre purchase, please contact our team of advisors, who are always happy to help.

Finding the correct tyre for your Implement Machinery involves knowing the correct tyre size. The size is usually written on the sidewall of the tyre and can be displayed in a number of different ways. We have detailed an explanation of how the different methods of measuring the tyre can be written below:

Two Number Imperial Tyre Sizes - e.g. "10.00 - 20

This measures the size of the tyres in inches. The first number denotes the overall width of the tyre which in the example above is 10". The last number is the diameter of the rim (wheel) in inches. In this example it would be 20"

Three Number Imperial Tyre Sizes - e.g. "10.0 / 75 - 15.3"

This measures the size of the tyres in inches. The first number denotes the overall width of the tyre which in the example above is 10". The middle number is the sidewall height of the tyre as a percentage of the width which is approximately 7.5" in the example above (75% of 10"). The last number is the diameter of the rim (wheel) in inches. In this example it would be 15.3"

Metric Tyre Sizes - e.g. "210 / 95 - 16"

This is the newer, 'metric' measurement where the first number is again the width of the tyre, but is measured in mm. In this case 210mm. The second digit represents the tyre sidewall profile (height) as a percentage of the width. In this example the sidewall height would be 95% of 210mm (approx. 199mm). The last digit is again the diameter of the rim (wheel), still measured in inches. In this example it would be 16"

There is more to choosing an implement tyre than just the size required. Implement tyres are made and tested to work under certain criteria and limitations and the tyre load /speed and ply ratings all help choose the correct tyre for the application. The load speed index (service Index) is usually clearly marked on at least one of the sidewalls of the tyres.

Load Index is the limit of weight that the tyre can safely carry. Manufacturers make and test the tyres to operate under a certain weight. Once the tyre has passed these tests, it is awarded a load rating. It is essential that the correct load rating is used for Implement machinery tyres. Trailers, balers and spreaders, all are designed to carry specific weights and fitting a tyre that doesn't meet these requirements can lead to premature wear, tyre damage or failure. This in turn reduces productivity and ends up costing more in the long term. Load indices are usually denoted by a number. The number itself is not the actual weight carried but represents the maximum weight that the tyre has been designed and tested for.  Most tyres have a load index between 0 (45kg's) and 170 (6000kg's). For more information on Implement load indexes, please refer to our load index chart on the Tyre Guide page.

Speed Rating is the maximum speed that the tyre has been designed to operate at. As with the load index, the speed rating is an important part of any tyre purchase. Ensuring you have the correct tyre for the job means better operation, reduced downtime and associated costs and increased overall value. Implement tyre speed indices are usually shown as a letter. lower speed tyres use A1 (3mph) to A8 (25mph). The higher speed rated tyres usually use B (31mph) to F (50mph).

Ply Ratings can be quite confusing in modern times and used to be the standard way to represent the overall strength of the tyre. Ply rating used to show how many plies of rubber that were used to make up the construction of the tyre. For example, if a tyre had a 10ply rating, it would be made up of 10 plies (layers) of rubber. Modern advances in tyre technology have lead to other materials than rubber being used and construction methods increasing the strength of the tyre. The PLY rating is less commonly used to convey the number of plies and is now more relevant in showing the strength of the tyre 'AS IF' it had that number of plies of rubber. Implement tyre ply ratings can still useful when used as a guide in assessing the overall strength of the tyre.
