It often feels like the only way to make savings with agricultural tyres is to negotiate cheaper tyres from your dealer. Think again! The savings you make on their purchase are nothing like what you could save over years of daily use.
Since your tyre is an essential part of your vehicle, establishing the only contact between the ground and your tractor, it is far more important than you think and the different technical parts which it affects may change everything in the results of your activity: it can save you time thanks to better traction and less slippage, it can save you fuel, help preserve your soils and therefore your yields. Not to mention savings on the mechanical wear of your tractor and tilling implements…
By choosing tyres that are more suitable to the actual use you make of them, technological tyres or simply by changing your habits, you can really begin to make savings which will be clearly visible at the end of the year.
Without changing your current tractor, you can capitalise more from its engine power if you have better traction. It’s your tyres’ direct role to optimise traction because they are the principal relay of engine power to the ground.
To limit the inevitable phenomenon of slippage and get a better grip on the ground, it’s always best to opt for high quality agricultural tyres which have been designed to optimise traction.
Often, when choosing a discount tyre model whose lug angle has not been studied in-depth, you will not obtain good traction and the tyre’s self-cleaning capacities may be reduced.
Don’t forget that without good slippage rate control you will lose a lot of time, increase fuel consumption and wear out your tyres more rapidly.
Choosing IF (Improved Flexion) technology tyres designed with more resistant materials allows you to use variations in pressure to improve traction.
IF agricultural tyres have reinforced sidewalls to obtain greater flexion, which means that they can work at very low pressure and therefore increase their contact patch with the ground. The lugs are perfectly applied to the ground and all the engine power can be used for traction.
FIRESTONE’s IF tyres have a multi-angle, curved lug pattern to ensure maximum self-cleaning. They enable soil preservation by reducing compaction while optimising tractive force to save time during tilling.
Of the different solutions to improve your vehicle’s traction, the use of dual wheels is the most efficient alternative.
This technique allows you first and foremost to obtain an excellent distribution of the load while reducing tyre pressure, thus considerably limiting the risks of soil compaction.
Basically speaking, dual agricultural tyres allow you to increase the size and the weight of the implements used, to improve your engine’s tractive power considerably, while reducing the slippage rate and impact on the ground.
This technique increases the rolling surface in contact with the ground by increasing the number of lugs which grip into the soil, which leads to better traction, but also has many other benefits:
Duals are particularly recommended for very powerful tractors and large surface areas.
While this option has benefits, there are also limitations. You cannot choose any old tyre; duals must be of:
All these constraints may represent a high cost, without mentioning the problem linked to the width of the vehicle when driving on the road.
This is a question which it is quite difficult to answer.
Slippage is directly linked to the weather conditions. Beyond a certain level of humidity, it is not reasonable to till the soil because the resistance of the earth decreases with the level of humidity and if your tyre does not meet any resistance when going forward, it will sink deeper to find the resistance necessary.
Beyond a 30% slippage rate there is a risk of the tractor getting bogged down and your vehicle will alter the quality of your soil more than doing the work intended.
Slippage is necessary in order to do a good job. The ideal slippage rate is thought to be in the region of 12% to 15%.

By opting for low-pressure IF tyres, you reduce the slippage rate, because these new generation tyres allow you to work at a very low inflation pressure. This means that you increase the contact patch with the ground while reducing the pressure exerted, thus mechanically reducing the slippage rate.
As your fuel consumption represents a recurrent charge that will impact your profitability directly, any optimisation is worthwhile to make savings and to limit your expenses.
If you opt for standard tyres, you will have to adapt tyre pressure depending on the type of ground on which you work, which takes a lot of time, given that the inflation pressure at which you work has a big impact on your fuel consumption.
If you work with overinflated tyres to cater for heavy implements for example, the tyres will sink deeper into the ground, the slippage rate will be higher, thus requiring more engine power to compensate for the higher rolling resistance. This type of situation can lead to extra fuel consumption equivalent to the value of a set of front or rear tyres at the end of the year.
Equipping your agricultural vehicle with low-pressure IF tyres will allow you to bear up to 20% more load than standard tyres, while working at a very low inflation pressure.
Your crops need aerated soil to develop and unfortunately the repeated passage of your machinery can result in excessive compaction, especially if you work with poor quality tyres which can have an impact on the compaction of your soils and their productivity in the long term.
To preserve your soils, it is highly recommended that you work permanently with low-pressure tyres on all your agricultural machinery.
IF tyres have an extensive flexion and deflection capacity thanks to their supple sidewalls, they can be used at a pressure of 0.8 bar in the fields without any risk of damage to their internal structure.
Using wider tyres with a higher volume of air allows you to spread the weight over a larger contact area with the ground, thus avoiding soil compaction and preserving biodiversity and the root system of your crops.
