Abstract
A pneumatic tire comprises a pair of bead portions each provided therein with a bead core made of windings of at least one wire, a carcass ply of cords extending between the bead portions and turned up around the bead core from the axially inside to the outside of the tire to form a pair of turnup portions and a main portion therebetween, a rubber bead apex disposed radially outside the bead core and between each said turnup portion and the main portion, and a fiber reinforced rubber spacer interposed between the bead core and the carcass ply to provide a positive distance between the carcass ply cords and bead core wire. The fiber reinforced rubber spacer has a securing portion which extends radially outwardly and axially outwardly from the axially inside of the bead core while separating from the bead core but contacting with the rubber bead apex. A distance (L , L ) between an outermost point of the securing portion and the bead core is in a range of from to times a height of the bead core.
