Types of dual wheel systems for agriculture and earthmoving
For combining dual wheels with the correct rim size and strength, it is important to select the right rim category. View our range of agricultural rims in the webshop.
What is a dual wheel system?
A dual wheel system (also referred to as twin fitment) consists of two tyres mounted side by side on the same axle. The additional tyre creates a wider wheel configuration, distributing the machine weight over a larger surface area. This reduces ground pressure and minimises soil compaction.
This system is widely used on tractors, harvesters and earthmoving equipment operating under heavy loads or in variable conditions.
The increased contact area reduces wheel slip and improves traction transfer. This results in more efficient operation, lower fuel consumption and better protection of soil structure.
Conclusion: dual wheels improve traction, efficiency and soil protection under demanding conditions.
Why use dual wheels?
Dual wheel systems offer several advantages:
- lower ground pressure due to a larger contact area
- increased grip and stability, even on slopes
- improved traction under heavy loads
- flexibility to switch between single and dual configurations
They are widely used across Europe in both agricultural and earthmoving applications.
Conclusion: dual wheels are a practical solution for improving performance in heavy-duty and soft-ground conditions.
Star system: robust and widely applicable
In a star system, a steel star is mounted onto the rim using bolts. This star acts as the central mounting point for the dual wheel. The second wheel is secured using a locking pin or quick coupling.
The star system is known for its stability under heavy loads and is ideal for applications such as ploughing, slurry spreading or pulling heavy implements.
The system is easy to mount and remove without special tools, allowing operators to quickly switch between single and dual wheel configurations.

Conclusion: the star system is a robust and reliable solution for heavy agricultural work.
Quick-release system: fast switching between single and dual
The quick-release system is designed for users who frequently switch between single and dual configurations. The base rim or star remains mounted on the machine, while the additional wheel is secured using a lever or clamp mechanism.
This allows for fast and user-friendly installation, making it ideal for seasonal work, changing soil conditions and operations requiring flexibility.
Conclusion: the quick-release system is ideal when speed and convenience are essential.
Cylinder coupling system: precise and durable connection
In a cylinder coupling system, two complete wheels are connected using a cylindrical tooth-and-hole construction. One wheel contains teeth, the other corresponding holes. Using a spindle, both parts are tightened together and secured with a locking pin.
This creates a very stable and durable connection suitable for heavy and continuous loads.
This system is commonly used on machines that operate daily under high traction forces or in intensive earthmoving applications.
Conclusion: the cylinder coupling system provides maximum stability and durability in demanding conditions.
Mounting and maintenance
Correct installation is essential for safe and efficient operation of dual wheel systems:
- both tyres must have equal tyre pressure
- rims must be clean and free from damage
- always use the correct star, quick-release or cylinder coupling system
- check offset, valve position and bolt torque
- regularly inspect locking mechanisms for wear

Conclusion: proper installation and maintenance are crucial for safety and performance.
Which system should you choose?
The right dual wheel system depends on:
- load requirements
- working conditions
- machine type
- frequency of switching
- The star system is suitable for heavy traction and intensive agricultural work
- The quick-release system is ideal for frequent configuration changes
- The cylinder coupling system offers maximum stability and durability
