First seen at the 2017 Sima Show, where it received a gold medal for innovation, Michelin’s EvoBib radial tyre has now been updated with the launch of a new version.
There’s a new tread design that’s said to optimise longevity and offer excellent traction capabilities until the end of the tyre’s life, and the EvoBib’s tyre casing is now Pressure Field Operation (PFO) rated, a standard that allows manufacturers to increase the load capacity of their tyres for field use.
Described by Michelin as a two-in-one tyre, the EvoBib was the first agricultural tyre on the market specifically designed to be used with central tyre inflation systems (CTIS), making it possible to obtain excellent performance on the road and in the field.
In the field, at low tyre pressures, the footprint is maximised due to the tread design and its very low-pressure structure – utilising Michelin Ultraflex Technology – that reduces soil compaction and improves the tractor’s traction capabilities.
In road use, the tyre pressures are increased and the reduced footprint and the central rib of the tread pattern cut rolling resistance, while longevity is improved and fuel consumption is reduced.
The new Michelin EvoBib offers a footprint variation of 47 per cent between road and field pressures, double that of a VF tyre such as the Michelin AxioBib 2 (24 per cent) that would conventionally have usually been used with CTIS.
Two sizes of Michelin EvoBib – VF710/70R42 and VF600/70R30 – are now available in the UK. They can be used on tractors between 200 and 300hp equipped with CTIS. The range will be expanded during 2023 with the addition of new sizes for tractors of more than 300hp.
