Abstract
Tires having a magnetic tire sealing material containing magnetic particles are described for detecting the presence of one or more sealed punctures in the tire. The tires can have a sealed tire portion that is formed by the magnetic tire sealing material flowing into and filling a puncture in the tire. The sealed tire portion includes a portion having magnetic particles and the portion being at the outer surface of the tire such as in the tread area. The tire can be positioned within the detection zone of an apparatus capable of detecting magnetic particles to indicate whether the tire contains a sealed puncture filled with the magnetic tire sealing material.
