There is a simple reason why manufacturers produce different tyre models. It’s not for the pleasure of creating a tyre size catalogue, but actually because there are very different kinds of strain imposed on your tyres depending on what you use them for. You know that to do a good job you need to be well equipped, and for your tyres this principle is very pertinent because, if you go beyond appearances, all tyres are very different at the level of their design and each category has been developed to obtain optimal efficiency and productivity in carrying out a specific task or for a precise use.
To improve productivity in field crop farming the tendency is to move towards increasingly powerful machines which are heavier overall and for which the main disadvantage is the resulting soil compaction.
The tyre has a major role to play in preserving your productivity. With larger tyres and a greater volume of air you can effectively increase your traction capacity, save time on your campaigns with bigger, heavier implements, reduce fuel consumption while preserving your soil from excessive compaction.
The latest generation low-pressure VF tyres allow you to carry 40% more load than normal tyres at a lower inflation pressure. Their very supple but extremely resistant sidewalls give them a larger soil footprint for a better load distribution. Furthermore, you will save time by keeping the same pressure in the fields and on the road, thus losing less time adapting inflation pressure between operations.
For field crops, harvesting is a major operation during which tyres are crucial. Indeed, if you have taken care to preserve your soil all year, it would be such a pity to harvest with standard tyres which will need an inflation pressure of 4 bar to bear the 37,600 kilos of the combine harvester, including 28,000 kilos for the loaded front axle.
The best tyres are those which will give you the maximum bonus load while maintaining a relatively low inflation pressure.
As well as being perfectly adapted to hilly fields, VT-COMBINE IF and VF CFO tyres allow you to work at a relatively low inflation pressure of 2.4 bar, whatever the load, which is a major advantage on top of the fact that you can maintain a speed of 15 km/h.
With VT-COMBINE IF and VF CFO tyres you can obtain an 86% bonus load:
Your tractor is used for the management of livestock farming, but also for working the land. It must therefore be equipped with polyvalent tyres which can withstand work in the farmyard with a front loader bucket, cope with frequent sharp turns and at the same time be supple enough to provide good traction in the fields with longer lugs to work at a low inflation pressure.
The VX-TRACTOR tyre, with its reinforced casing, is particularly adapted for this type of activity. Certain tyre sizes have 6 layers of rubber on the tread to provide stability in all circumstances and a high level of resistance during work on hard surfaces or transport by road.
These tyres have longer lugs than a normal tyre to provide better traction in the fields and more than 20% more rubber containing components that are resistant to wear, thus ensuring exceptional durability.
Vines and orchard trees are highly specific because their root systems need to be able to develop over several years and soil compaction must be avoided as this would be damaging to good development. In addition, the vehicles systematically follow the same path between the rows, leading to highly localised and excessive compaction.
The use of low-pressure vineyard tyres is a good solution because their considerable deflection capacity allows them to work at low pressure, while spreading the load over a larger soil footprint.
It is impossible to drive between crop rows with wide tyres without damaging young seedlings. In addition, your trailer must be equipped with supple tyres to optimise the stability of the spraying boom which is severely tested by the swaying movement of liquid in the tanks, which is where choosing the right tyres can help you do a better job.
Using your very supple VF tyres which are intended for use in field crop farming to carry out forest clearing work or occasionally to work on a construction site would be a serious error, because these tyres are designed to avoid soil compaction and they will not withstand roots, branches or sharp stones for very long.
The best option is to use tyres that are intended for forestry work. These tyres are extremely different in terms of their design, with a diagonal structure that provides greater resistance in the sidewalls than radial tyres.
They are reinforced by one or more steel belts which are added to the casing and its different nylon plies. The layer of rubber in the sidewalls is increased by 20% to prevent tears and perforation and these tyres are used at a high inflation pressure with no consequences to the ground in the forest or to the concrete of a construction site.
