Abstract
A pneumatic tyre includes a sensor device for monitoring one or more dynamic parameters of the tyre and a detecting device. The sensor device is disposed in a crown portion of the tyre and includes an inertial switch. The inertial switch changes from a first state to a second state when the crown portion begins contacting a ground surface and changes from the second state to the first state when the crown portion loses contact with the ground surface. The detecting device is operatively connected to the inertial switch and determines the one or more dynamic parameters of the tyre from a signal obtained from the changes of the inertial switch. A method for monitoring the one or more dynamic parameters includes providing the tyre with the sensor device disposed in the crown portion, rotating the tyre on the ground surface, and determining the one or more dynamic parameters.

17. A method for monitoring one or more dynamic parameters of a pneumatic tyre, comprising:
-
providing the tyre with a sensor device disposed in a crown portion of the tyre;
rotating the tyre on a ground surface; and
determining the one or more dynamic parameters of the tyre;
wherein the sensor device comprises an inertial switch, wherein the inertial switch changes from a first state to a second state when the crown portion begins contacting the ground surface, wherein the inertial switch changes from the second state to the first state when the crown portion loses contact with the ground surface, and wherein the one or more dynamic parameters of the tyre are determined from a signal obtained from the changes of the inertial switch. - View Dependent Claims (18, 19, 20, 21, 22)
