Abstract: A method and system for estimating the load acting on a tire, wherein data are obtained, representative of the deformation undergone by the tire on a rolling surface. The data obtained are processed in order to obtain a first quantity representative of the deformation extent within a first deformation region substantially corresponding to the footprint between the tire and the rolling surface and a second quantity, different from the first quantity, representative of the deformation extent in a second deformation region, the second region including the first deformation region and having a circumferential extension greater than the circumferential extension of the first deformation region, the second quantity being obtained starting from at least a part of the obtained data, which corresponds to a portion of the second deformation region which is external to the footprint. The load is estimated based on the first quantity and the second quantity thus obtained.

Abstract: Fastened to a tire is a detecting device consisting of a detecting unit including an antenna operatively connected to a sensor unit and a power supply unit including a piezoelectric element mounted in a housing. The piezoelectric element is disposed within the housing so as to have a first end substantially fixed to the housing and a second end associated with a loading mass, a gap being formed between at least one inner wall of the housing and an outer surface of the loading mass.

An anchoring body has a base portion with a fastening surface secured to the radially internal surface of the tire. The detecting unit is brought into engagement with the anchoring body by insertion of the inner perimetral edge of the antenna into a perimetral groove formed between the base portion and a retaining portion.
