Abstract
A pneumatic tire of the tubeless type, embodying a layer of puncture sealant composition based on: PA1 A. a major proportion of a low molecular weight elastomer (e.g., depolymerized natural rubber) in admixture with a tackifying or plasticizing substance (e.g., a resinous reaction product of a mineral oil purification residue with formaldehyde) and PA1 B. a minor proportion of a high molecular weight elastomer (e.g., cis-polyisoprene); PA1 Containing a crosslinking agent (e.g., tetra-n-butyl titanate) in an amount sufficient to give a partial cure.
