In a method of detecting an occurrence of hydroplaning of a tire of a vehicle travelling on wet ground, a tread of the tire of the vehicle is equipped with one or more sensors each capable of measuring a compression experienced locally by the tread when the tire is rolling on the ground and of producing a signal corresponding to these measurements. According to the method, measurements are obtained of a compression when the tire is rolling on the ground; a signal corresponding to these measurements is produced; a portion of the signal relating to a passing of one or more sensors into an apparent area of contact between the tire and the ground is extracted; an instantaneous value (&Dgr;E, Rz), corresponding to a presence of an indirect contact region of the apparent area of contact between the tread and the ground, is determined from the extracted portion of the signal; and an alarm is triggered when the instantaneous value satisfies a given relationship.
