Michelin launches new agri-tyre
Cereal farmers, contractors and farm- machinery cooperatives are to benefit from the launch of a new Michelin tyre, which can help reduce the stress and hassle associated with moving combine harvesters by road, whilst delivering increased productivity on the farm.
Developed in conjunction with agricultural machinery manufacturer Claas, the Michelin CerexBib delivers an unrivalled advantage through being 15 per cent narrower than any conventional harvester tyre. This reduced width allows manufacturers to build larger harvesters without exceeding a width of 3.5 metres; the critical point at which European Union regulations stipulate that harvesters require special order movements from the Police and on-road escorts.
Michelin says the key to achieving this impressive performance advantage is its patented Ultraflex technology, with CerexBib being the only commercially available harvester tyre which can work at a pressure of less than 2 bar (29psi). This is around 30 per cent less than conventional tyres.
A Michelin CerexBib IF* 680/85 R 32 - one of four sizes available from launch - has the same load capacity as the current 800/70 R 32, yet benefits from a footprint which is 20 per cent larger thanks to more flexible sidewalls. This increases opportunities to harvest, no matter how wet the weather, whilst the low operating pressure of just 1.6 bar (23psi) ensures that soil compaction is reduced, protecting fields and maintaining their full crop yield potential.
The pressures of modern faming have driven a requirement for more powerful and wider harvesters to improve productivity, with the latest combines featuring larger harvesting headers, increased threshing capacity and even more powerful engines, which has increased overall machine size and weight significantly.
