Properties of a tire with sensor signals of speed of deformation

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, and
• wherein 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.
