NEW HOLLAND COMBINE HARVESTER CR11: fitted MICHELIN Ultraflex technology tyres

These two new sizes are designed to meet two significant technical challenges:

The load capacity of the new machine, with its much larger hopper (20,000 litres) and much wider header (15 metres).

The constraints concerning the diameter and width of the vehicles to comply with the various European regulations for road transport.

These new sizes, offering an exceptional load capacity of 19 metric tons per tyre, and an impressive diameter of 2.32 metres (for the MICHELIN CEREXBIB 2 VF900/65R46 CFO size), represent a major advance in agricultural tyre technology.

Combined with a new rear axle configuration, these high-performance tyres not only increase the vehicle's footprint by 23%¹ and reduce ground pressure by 7%² , but also optimise overall fuel consumption. In effect it is the only range on the market offering a cyclic load bonus of 10 km/h to increase the load or reduce the pressure in the tyres. This speed corresponds to the average speed of the machines at work.

This technical feat has been successful thanks to the patented MICHELIN ULTRAFLEX TECHNOLOGY, a major Michelin's innovation in the area of agricultural tyres.

The innovative MICHELIN ULTRAFLEX TECHNOLOGY, launched in 2004 with the MICHELIN XEOBIB tyres, is celebrating its 20th anniversary, marking two decades of innovation in the area of agricultural tyres.
This innovative technology provides a larger footprint on the ground, protecting it from compaction and rutting for increased productivity. A study by England's Harper Adams University, begun in 2012, shows that tyres with MICHELIN ULTRAFLEX TECHNOLOGY, inflated at low pressure, increase yields by 4%³. This technology was associated with the very first industrial standard - VF* (Very High Flexion), followed by IF** (Improved Flexion) from 2006. Together, these two norms have re-defined the use of low-pressure tyres.

¹Based on Michelin internal calculation: sum of 4 tyres on CR11 machines (VF900/65R46 CFO / VF10/65R30 CFO) vs CR10.90 (VF900/60R38 CFO / VF620/70R30 CFO) in maximum field load condition.

² Based on Michelin internal calculation: the sum of the footprints of the 4 tyres divided by the total machine load CR11 vs CR10.90 in maximum load field condition.

³ Haper Adams study started in 2012

* VF representing extremely high levels of flexion providing a 40% reduction in pressure and a 40% increase in the load;

** IF: improved flexion providing a 20% reduction in pressure and improving the load capability by 20%.
