The Effect of the Tractor Tires Load on the Ground Loading Pressure

The contribution, based on the experimental measurement, analyses the issue of a specific pad loading pressure in relation to radial wheel load and tire inflation. Tile inflation in terms of allowed radial load, which we wish to be high as far as possible in terms of the power transmission from the wheels to the ground is important for the field tensile works, on the other hand, the pressure in the tire is closely related to the contact area and ground loading pressure. The obtained results show the following: Michelin Multibib 650/65 R38 tire, inflated to a pressure of 80 kPa has a sufficient reserve in radial load. As the measurement results show, ground loading pressure at the highest load of 36.55 kN, which was used during the measurement, is under the value of 100 kPa, which would mean on loamy soil at a humidity of 17 % that the limit of the ground pressure on the ground has not been exceeded.
Keywords: stress transmission, tire inflation pressure, area of imprint, pressure in area of imprint
