Study shows Michelin Agri tyres lead to reduced soil compaction

ERJ staff report (DS)

Stoke-on-Trent, UK - A trial conducted by an independent soil

scientist has found significant differences in the level of soil compaction from

a combine harvester, depending on the make and type of tyre fitted. This can

have a significant impact on plant root growth and yield potential.

The trial was carried out by Philip J Wright BSc (Hons) C Eng MI AgrE, of Wright

Resolutions, using a Claas Lexion APS Hybrid

Combine at the manufacturer's headquarters in Saxham.

It tested Michelin's new CerexBib combine harvester tyre against other tyres from Michelin and competing manufacturers.

The recorded data found a significant difference in the mean level of soil

compaction between the CerexBib and other tyres.

The CerexBib fitments created a significantly lower level of compaction, mean

1099kPa, compared to the other makes of tyre. Michelin's MegaXbib (front) and

MachXbib (rear) fitment recorded a mean compaction of 1425kPa, compared to

1506kPa and 1603kPa for the two other tyre brands.
