摘要： A heavy duty radial tire is to be mounted on a 15 degree drop center rim. In a mounted state that the tire is mounted on the rim and inflated to 0.5 ksc but not loaded, the inside diameter BC of the bead cores at the radially innermost point thereof is set to being not more than the diameter BT at the heel point of the bead portions. In a demounted state that the tire is demounted from a rim, the bead bottom is tapered towards the axial inside of the tire at an angle .theta. of from 1.0 to 1.9 times the angle .alpha. of the tapered bead seat of the rim. In the mounted state, the bead core has a radially inner surface tapered at the substantially same angle as the bead seat, and the axial distance BP of the axially inner end of this tapered inner surface from the bead heel point is set in the range of from 1.3 to 2.1 times the maximum width BW of the bead core measured in the direction parallel to the bead seat. A straight line drawn between a point P2 at which the carcass main portion starts to contact the bead core and a point P3 at which the carcass main portion and a radially extending straight line passing the axially inner end of the radially inner surface of the bead core intersect each other, is inclined at angle .beta. of from 45 to 60 degrees with respect to the tire axial direction.

摘要： 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 (L1, L2) between an outermost point of the securing portion and the bead core is in a range of from 0.05 to 1.0 times a height of the bead core.
