International Classification:

B60C 710

US Classification:

152 7, 152 47, 152326

Abstract:

The present invention is a non-pneumatic tire comprising a rim and one or more elastomeric materials bonded to the rim or to one another. The tire has an equatorial plane, an annular tread, and an annular elastomeric body having first and second spaced lateral sides equidistant from the equatorial plane and extending between the tread and the rim. The tire body has a plurality of equally spaced arches forming at least a first series of openings extending from the first side to the second side. The first openings having a height at least one-half the height of the tire side.

Abstract:

This invention relates to a pneumatic tire with puncture sealing property and a method for preparing such tire. Such tire is prepared by building an uncured butyl rubber-based layer, which contains a peroxide and a dispersion therein of a particulate precured rubber selected from pre resin-cured butyl rubber and/or pre sulfur-cured diene-based elastomer, into an uncured tire and between an innerliner layer and the tire carcass. Upon curing the prepared tire under conditions of elevated temperature, a major portion of the uncured butyl rubber composition is depolymerized to form a tacky material, which contains said dispersion therein of said particulate precured rubber, which has puncture sealant properties. Such layer of depolymerized butyl rubber and dispersed precured rubber particles may be collectively referred to as the sealant layer.
