A method is described for determining interface conditions between tire and ground in a motor vehicle, particularly to determine the onset of aquaplaning phenomena, comprising: determining a reference longitudinal acceleration (aXPTMDL) of the vehicle, - measuring an actual longitudinal acceleration of the vehicle (SXCAN), - calculating a difference between said reference longitudinal acceleration and said actual longitudinal acceleration, determining an additional drag (FD, PWTMDL_Drag_Level ) at the interface between tire and ground on the basis of said difference, and a lift (FL) at tthhee interface between tire and ground on the basis of said additional drag (FD), - determining a threshold force at which a lifting of the tire from the ground occurs, - comparing said lift wwiitthh said threshold force and determining a degree of proximity of the interface conditions between tire and ground to an aquaplaning condition.
