Abstract
A puncture-sealing pneumatic tire has a soft, vulcanized inner layer consisting of cis-polyisoprene rubber and/or natural rubber. The inner layer is preferably coated with a polyolefin polymer that flows into punctures at operating temperatures and said polyolefin polymer adheres to the inner layer by means of surface tension alone.
