Single or dual assembly for agricultural tyres?
Advantages and disadvantages
The main advantages of dual assembly are better distribution of soil pressure, improved tractor stability and higher tractive force. This means loads are spread over more tyres, which means tyres are less likely to slip and thus be subject to less wear and tear. Finally, dual assembly also helps to reduce fuel consumption.
However, an extra wheel next to an existing tractor wheel also has its disadvantages, like an increase in the total width of the machine. After all, two tyres instead of one makes a big difference, even if you opt for a thin second tyre. Other disadvantages include higher rolling resistance, lower comfort and more difficult steering.
Why dual assembly?
A double assembly system is a practical and economical solution. But make sure you make the most of it. If, for example, you want to avoid compaction, you must also adjust tyre pressure if you decide to mount two tyres on each side. This is the only way dual assembly will offer clear advantages. This can be attributed to the three-way relationship between load, speed and air pressure.
Opt for dual wheel for lower load per tyre
This will certainly help to reduce track-forming and soil compaction. However, in order to maximise the effect, tyre pressure must be adjusted. Only then will double assembly offer clear benefits. This can be attributed to the three-way relationship between load, speed and air pressure. It also offers benefits for the driver: double assembly help to improve the tractor’s stability. One of the downsides of double air is that it makes machines wider.

Solutions for difficult conditions
Modern combinations of tractors and agricultural machines continue to become heavier. However, this can cause many problems with poor site conditions. The vehicles will sink into the ground, the soil structure will be damaged, grip will decrease and fuel consumption will increase.
The principle of dual wheels can be useful in such circumstances: this involves mounting an extra wheel next to the existing tractor wheel. Many people prefer to do this rather than mount wider (IF/VF) tyres. That's because the dual wheel system is a practical and financially appealing solution.
Using an extra wheel next to the existing tractor wheel is advantageous because it offers extra traction and reduces track-forming or soil damage. In addition, fuel consumption is reduced and tyres are less likely to slip, reducing wear and tear.
