Tires having an electrically conductive tire sealing material containing metallic electrically conductive particles are described for detecting the presence of one or more sealed puncture areas in the tire. The tires can have a sealed tire portion that is formed by the electrically conductive tire sealing material flowing into and filling a puncture in the tire. The sealed tire portion includes a portion having electrically conductive particles and the portion being at the outer surface of the tire such as in the tread area. The tire can be positioned to be in contact with a conductive section of an apparatus capable of measuring electrical conductivity.
