A pneumatic tire casing have at least one sidewall ornamental with patterns being made of an elastomer of a color different from that of the sidewall which covers the carcase of the tire, by compelling during moulding and vulcanization of the tire a thin layer of elastomer of a color different from that of the sidewall into the width of the latter, so as to obtain that said layer becomes arranged at the bottom of a recess formed in a part of the outer surface of the tire casing.

Pneumatic tires having ornamented sidewalls, and to their manufacture

Pneumatic tires having ornamented sidewalls, and their manufacture

A pneumatic tire cover has a carcase comprises at least one inner radial ply of threads of aromatic polyamide and at least two outer plies of threads having elongation values greater than those of the said aromatic polyamide and arranged in alternately crossing directions from one of said outer ply to another, while the inner radial ply or plies are such as to be able to bear the inflation pressure on its or their own.

Structure of pneumatic tire covers

A pneumatic tire cover with a radial carcass in which at least one ply of the carcass is folded upon itself by a prefixed amount, along its longer sides, that is, in those parts of the ply which are anchored to the bead cores about which they are folded or which, not being folded around the bead cores, reach the zone of the cover in proximity to the bead cores themselves.
