Abstract

A non-pneumatic tire may include a support structure having an inner circumferential portion configured to be associated with a hub. The tire may further include a tread portion associated with an outer circumferential portion of the support structure. The tire may also include at least one sensor associated with at least one of the support structure and the tread portion and configured to generate signals indicative of at least one characteristic associated with at least one of the support structure and the tread portion. The tire may further include a receiver associated with at least one of the support structure and the tread portion and configured to receive signals from the at least one sensor. The tire may also include a transmitter associated with at least one of the support structure and the tread portion and configured to transmit the signals to a location remote from the tire.
