Abstract
A puncture-sealing pneumatic tubeless tire comprising a sealant as its innermost layer and a tack layer disposed between said sealant and the air impervious liner. The tack layer is integral with the tire and allows the application and adherence of the sealant to the tire without first cleaning the inside of the tire. The tack layer is a soft, vulcanized layer consisting of cis-polyisoprene rubber and/or natural rubber.
