New version of Michelin ‘2-in-1’ EvoBib tyre launched

Michelin has launched a new version of its ‘2-in-1’ EvoBib tyre – the first agricultural tyre on the market specifically designed to be used with Central Tyre Inflation Systems (CTIS), which makes it possible to obtain performance both on the road and in the field due to its adaptive design.

In field use, the footprint is maximised due to the tread design, and its very low-pressure structure – utilising Michelin Ultraflex Technology – which reduces soil compaction and improves the tractor’s traction capabilities.

In road use, 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 tread design has also been adapted to optimise longevity and offer excellent traction capabilities until the end of the tyre’s life. In the new EvoBib, the tyre casing is now PFO (Pressure Field Operation) rated, a standard that allows manufacturers to increase the load capacity of their tyres for field use.

Michelin says the new EvoBib has a footprint variation of 47 per cent between road and field, double that of a VF tyre such as the Michelin AxioBib 2 (24%) that would have usually been used with a CTIS.

Michelin claims the new EvoBib increases in traction by 15 per cent compared to a competitor’s VF tyre with a hybrid tread pattern, and the same traction capability as a VF tyre with a lug tread pattern (under normal field conditions).

Fuel consumption is also improved, Michelin says, close to that obtained using a standard road profile tyre. While there’s a reduction in consumption of two litres per hour compared to a competitor’s hybrid VF tyre, and a reduction of 1 litre per hour compared to the Michelin AxioBib 2 with CTIS.

Two sizes of the Michelin EvoBib – VF 710/70 R 42 and VF 600/70 R 30 – are now available, which can be used on tractors between 200 and 300 hp, equipped with CTIS.

Michelin says the range will be expanded in 2023 with the addition of new sizes for larger tractors of more than 300 hp.
