The invention relates to a reinforced valve group for inflating tyres, suitable to be stably associated to a transducer for TPMS technology. Such a group comprises a valve, with a hole 114 provided with an internal thread 214 and a stem 18 provided with an external thread 215, and a locking nut 5 screwed on the external thread 215 of stem 18 of valve 1. The group is provided with a reinforcement area 17 formed by an overlapping portion Ls between the external thread 215 and the internal thread 214, so that, once screwed, the locking nut 5 overlaps at least partially the internal thread 214. In addition, during the screwing of a fastening screw 4 of transducer 3, such a screw goes back up in correspondence with the external thread 215, and continues beyond, thereby acting as a support and reinforcement at a critical point of the valve (1).
