Clip-on duals compared to IF and VF tyres

Clip-on duals, also known as snap-on duals or dual wheels, are an aftermarket product that can be attached to the existing wheels of a vehicle to provide additional support and load-carrying capacity. They are typically used on agricultural machines, trucks, trailers, and other heavy-duty vehicles.

Compared to IF (Increased Flexion) and VF (Very High Flexion) tyres, clip-on duals provide a different type of benefit. IF and VF tyres are designed to provide a larger contact patch with the ground, which can improve traction and reduce soil compaction. They are often used in agricultural applications where minimising soil damage is important.

Clip-on duals, on the other hand, are primarily used to increase the load-carrying capacity of a vehicle. They can help distribute the weight of the load over a larger surface area, reducing the pressure on each individual tyre. This can help prevent tyre damage and prolong tyre life.

While IF and VF tyres can also help distribute weight and reduce pressure on individual tyres, they do so primarily through their design and construction rather than by adding additional wheels. However, it’s worth noting that both clip-on duals and IF/VF tyres can be used together for maximum load-carrying capacity and reduced soil damage, depending on the specific needs of the application.
