Single or dual assembly for agricultural tyres?

Things are simple for trucks: they either have a single axle or a double axle. But a real choice must be made in the agricultural sector: will you opt for single or dual assembly? People often ask themselves this question when driving heavy machinery on poor surfaces. Subsidence, soil damage, diminishing grip and increasing fuel consumption… all good reasons for considering dual wheel assembly. But when will this choice be justified? We will be pleased to assist you!

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.

Load, speed and air pressure

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.
