Two additional size have been added to Continental's VF CombineMaster agricultural tyre range.

Following the successful uptake of the first three sizes since their launch in 2020, the 620/70R26 and 750/65R26 sizes have been added to complement the range.

“The new tyre sizes are designed for the steering axles of harvesters and for all positions on loader wheels. The HexaBead technology helps the tyre to grip the rim at lower pressures which can help to reduce soil compaction,” pointed out Continental's agricultural tyre specialist, Richard Hutchins.

Combine harvesters have to withstand both cyclical loads in the field and high speeds on the road. “On muddy ground, the VF CombineMaster offers great traction when loading and can be used with 40% less tyre pressure for the same load as a standard tyre, which helps to reduce soil compaction or can carry 40 percent higher load at the recommended pressure,” said Mr Hutchins.

The HexaBead core technology allows the carcase material to wrap around the bead in a more effective way, which improves power transmission, he added. “HexaBead also maximises the load capacity of the carcase. The technology was developed specifically for combine front tyres and loaders and ensures high torque transfer from the rim to the tyre."

VF technology allows the tyre to be used at lower air pressure, which means that the tyre can be driven without pressure adjustment to the weight of the load and the ground without degradation.

In addition, the combination of patented N-flex technology and innovative d-fine lug technology ensure added flexibility with low vibration at the carcase and high resistance to wear.

• Case IH Vestrum, Maxxum and Puma tractor series can now be made available with Continental TractorMaster and VF TractorMaster tyres. This partnership is the fourth Continental has secured since relaunching its agricultural tyre range in 2017 – it started with approvals from John Deere and Fendt, Valtra and now Case.
