Abstract: A motor vehicle tire is disclosed with a pair of post-cure run-flat inserts, each of the pair of post-cure run-flat inserts is disposed within a tire cavity between a shoulder region and a respective upper sidewall region of the tire. The tire further includes a cylindrical sidewall defining an interior cylindrical cavity, each of the cylindrical sidewall and the interior cylindrical cavity extending 360 degrees about a rotational axis of the tire, the cylindrical sidewall having an exterior surface contacting a radially inner surface of an inner liner between the shoulder region and the respective upper sidewall region during a normal inflation condition of the tire.

Abstract: This disclosure relates to an approach for monitoring a tire for a puncture based on a change in a voltage established based on a resistance of a material disposed within the tire. In one example, the material is a conductive material layer. In another example, the material is a resistive strip. The systems and methods described herein can monitor for a change in an established voltage over time that is a function of parameters including the resistance of the conductive material layer or the resistive strip, and an applied voltage, to provide an indication of the change in the resistance in the material. The change in resistance of the material can be indicative of the puncture within the tire. The systems and methods described herein can alert a vehicle operator of the puncture within the tire.
