Did you know that using a good tractor tyre can lead to considerable savings?
Up to €4,000 per year depending on the size and quality of the agricultural tyre used.
You can, of course, save on costs by opting for bottom-of-the range equipment, by choosing a low-cost agricultural tyre or old second-hand tyres that you patch up. Yet you might be surprised to discover that tyres which are more expensive to buy may prove to be more economic in the long run, especially when used intensively.
Fuel represents 30% to 50% of energy consumption in farming. This is a large share of the farm’s budget. Due to this, in order to save on costs, it is essential to optimise the fuel consumption of your tractor and agricultural machinery.
Your tractor’s fuel consumption depends on several factors: on the crop growing methods used, on your management of crop cycles but also on the choice of your equipment and especially the most suitable agricultural tyre.
To make fuel savings, it is not always easy to change your crop management model and limit the number of times your tractor has to cross the fields. It is far simpler to use better tractor tyres.
Your tractor’s original tyre mount is not the best, it’s simply the cheapest for the manufacturer. The size of the tyres must be adapted to the use of your tractor (sowing, ploughing, transport, etc.), its power and the type of soil.
A farmer in the UK (who took part in the Efficient 20 project*) reduced his fuel consumption by 30% by replacing his original tractor tyres with more suitable tyres (135 hp) for ploughing operations (5 furrow plough).
The tread pattern of your agricultural tyres contains a lug design. The angle of the lugs compared to the axis of the wheel affects your tractor’s pulling power. The shallower the angle, the greater the tractive force. But beware! Do not turn to low-cost models with an angle that is too shallow because this leads to cleaning problems. A badly cleaned tyre leads to loss of grip and increased slippage, which has a direct impact on fuel consumption.
As slip ratio of more than 15% leads to horizontal sliding of the superficial layers of soil and damages the soil structure. In addition, the actual distance covered by the tyre, which is further than the distance driven by the tractor, leads to additional fuel consumption: 20% excess fuel consumption with a slip ratio of 30% to which premature wear of the tyres must be added.
Not only does the right pressure in an agricultural tyre lead to better soil preservation and improve yields, it also allows you to reduce your energy consumption.
Depending on the type of work to be carried, the weight on the axel, the front or back load or the speed at which your tractor must travel, air pressure must be adjusted in order to be optimal. Overinflated tyres can put too much pressure on the ground, leading to excess soil compaction. The structure of an underinflated tyre will wear prematurely.
You must find the optimal tyre pressure which will allow the tyre to have the largest possible contact with the ground and as such improve the motricity of your tractor.
Optimised pressure can save 10% on fuel compared to maximum pressure, which is the pressure recommended for use on the road.
There are plenty of websites and apps developed by the major brands to help you calculate this optimal pressure.
Bridgestone has developed its own apps; Tyre Pressure Bridgestone and Firestone (available for Android and Iphone). They will help you to regulate inflation pressure. Choose your tyre from among more than 200 references, then indicate the load. You will automatically obtain the optimal tyre pressure to adopt.

If you choose a low-pressure VF tyre, you will be able to work with a low tyre pressure, whatever the type of work you are doing, and you won’t have to make continuous tyre inflation adjustments. You will save a considerable amount of time. In addition, the reduction in fuel consumption means that after two years you will have reached the same point financially as if you had bought a cheap tractor tyre. Starting from the third year, the difference in fuel consumption is transformed directly into net margin, and that is without taking account of all the benefits of this VF technology.
To find out how you too can save on fuel, download the free Efficient 20 report, based on the European project which took place between May 2010 and April 2013. Its aim was to create a network dedicated to fuel savings in the agricultural and forestry sectors, with the objective of achieving the European Union's target of 20% energy savings by 2020.
