Puncture sealing composition and tire

A pneumatic tire of the tubeless type, embodying a layer of puncture sealant composition based on a major proportion of low molecular weight liquid elastomer with a minor proportion of a high molecular weight elastomer, containing a crosslinking agent in an amount sufficient to give a partial cure. An example of the composition of the invention is a blend of 60 parts of depolymerized natural rubber and 40 parts of cis-polyisoprene, partially crosslinked by the action of 6 parts of tetra-n-butyl titanate so as to provide a gel content of about 40%.
