Abstract
A pneumatic tire for a motor vehicle having a tread, beads and a radial carcass combines a carcass having radially disposed cords which extend from about one bead cord to about the other bead cord and having a strip of metal cords which extend substantially perpendicularly to the circumferential axis of the tire, a breaker structural member disposed between the carcass and tread having at least two superimposed layers of cords which are disposed in each layer to cross those of the adjacent layer and a layer of heat shrinkable cords disposed parallel to the equatorial plane of the tire, and a sidewall reinforcing structure of cords which are disposed radially outwardly of the radially disposed cords of the carcass. The cords of the sidewall reinforcing plies are parallel to each other and are inclined at an angle of 20.degree. to 30.degree. with respect to the circumferential line of the tire. The reinforcing ply for the sidewall is folded and the fold is disposed between the carcass and the breaker structure. The longer skirt extends from the fold to the bead core cord while the shorter skirt is disposed axially outwardly from the longer skirt and extends from the fold through about one-half of the section height of the tire.
