Seven tractor-driving finalists in the European Drivers Challenge have been invited to the Michelin Technical Innovation Centre Test Circuit in Ladoux, France to demonstrate how best practice can affect tractor performance. Each participant will get his own John Deere 6215R AutoPowr tractor, pulling a heavy 20t Joskin two axle trailer. The tractors will be equipped with Michelin MachXBib tyres, with trailers featuring Michelin CargoXBib High Flotation tyres. The participants will be challenged to select their own strategy of tractor settings and tyre inflation pressures.
