Release the pressure and watch your diesel fuel bills plummet

By lowering air pressure in their tractor tyres, farmers could make significant fuel savings in addition to reducing the soil damage that their tractors are causing on soft ground.
That's the advice from tyre specialists Michelin, who demonstrate how it can be done on a YouTube video accessible on the Michelin channel and available at the link http://tinyurl.com/9ubxqcp ?
The video experiment features two Fendt 724 tractors, both fitted with Michelin's new Ultraflex XeoBib tyres.
One set is inflated to conventional pressures of 21 psi front and 23 psi rear, while the other is inflated to very low pressures of nine psi front and 10 psi rear.
By lowering air pressure, the video shows how the design of the more flexible sidewalls enlarges the contact patch to create shallower ruts, reduce wheel slippage, deliver greater speed and cut down on soil damage.
In a parallel demonstration, viewers can also see how significant fuel savings in the order of 20pc can be made by using these pressures.
As seen in the pictures, fuel use was accurately measured in both scenarios in the experiment through the use of vertical glass columns which showed how much diesel was burnt for each run.
Using the tractor running on conventional pressures, there was 9cm of fuel left in the glass column after the experiment.
