All the measurements for the contact area A occurred are carried out for stationary tyres. For an estimation of the dynamic contact area, it is recommended that the dynamic load for traction tyres be taken into account. The connection between the wheel load and the tyre size of a traction tyre and of a trailer tyre is not similar. Consequently it is necessary to develop and use distinct relationships to evaluate A of farming tyres. By low loading, A can increase with an increase of inflation pressure. For reliable estimations, loading values above 50% of the maximum permissible load are recommended. By estimating A, the aim is henceforth to provide a parameterization of soil hardness while also considering tyre stiffness.
