A system for measuring the grip between a vehicle wheel tire and a road surface comprising a fiber optic (19) provided with FBG sensors (21) affixed to the internal surface of the tire, which record data regarding the state of state of residual grip Grs of the tire to the road. The fiber optic (19) has an end part (20) which, through an optical joint (5, 6) transmits the data to an instrumentation of the vehicle, making it pass through a spectrum analyzer (12), a data processing system (14), which implements the residual grip identification algorithm Grs. The residual grip information is sent to a display that is visible by the driver and/or to active control systems for driving the vehicle.
