1. A method for measuring at least one characteristic property of a pneumatic tyre for a vehicle wheel, comprising:

  • arranging at least one array of deformable sensors along a first direction;

    making the tyre pass at speed over the at least one array of sensors along a second direction;

    generating, for each sensor, an electrical signal proportional to a speed of deformation of the sensor when the tyre contacts the sensor;

    detecting the electrical signal generated by each sensor; and

    determining, starting with the detected electrical signals, the at least one characteristic property of the tyre;

    wherein the second direction is a motion direction of the tyre,wherein the first direction is transverse to the second direction, andwherein the at least one array of sensors extends in the first direction for a distance greater than or equal to a dimension of the tyre in the first direction.
