A tire 2 includes a tie gum 24 between a carcass 12 and each chafer 22. In the tire 2, an inner liner 20 is formed from a thermoplastic elastomer composition including a styrene-isobutylene-styrene block copolymer. The inner liner 20 has a thickness of not greater than 1.5 mm. The tie gum 24 joins the inner liner 20 and the chafer 22 and has a volume resistivity of not greater than 10.sup.8 .Math.cm.

A pneumatic tire according to the invention includes: a pair of left and right beads 3 each including a bead cores 3a and bead fillers 3b; a carcass ply 5 extended around the bead cores 3a; and an inner liner 4 arranged on an inner peripheral side of the carcass ply 5, and is characterized in that the carcass ply 5 is wound up around the bead cores 3a from the outside in the direction of width of tire to the inside in the direction of width of tire, and a distortion restraining layer 7 configured to restrain distortion of the winding ends 5a of the carcass ply 5 is provided between the bead fillers 3b and the carcass ply 5 so as to overlap with a wind-up ends 5a of the carcass ply 5.

Tire having two beads having an annular reinforcing structure and a carcass reinforcement anchored in the two beads by a turn-up. Each bead has a bead rubber filler extending a radial distance from the radially innermost point of the annular reinforcing structure of the bead. The radial distance is not more than 10% of the tire's radial height. A sidewall has rigidifying metal reinforcing elements oriented along an angle not more than 10 to the circumferential direction and positioned with the distance between the radially innermost point of the annular reinforcing structure and the radially outer end of the rigidifying reinforcement between 20% and 40%, inclusive, of the tire's radial height and with the distance between the radially innermost point of the annular reinforcing structure and the radially inner end of the rigidifying reinforcement not more than 20% of the tire's radial height.

A pneumatic tire includes a bead part having a bead core, and a carcass layer folded around the bead core in the bead part. The bead part includes a bead inner-face part defined as a region at an inner side of the carcass layer in a tire width direction and at an outer side of a bead toe in a tire radial direction, a bead base part defined as a region at an inner side of the carcass layer in the tire radial direction and at an outer side of the bead toe in the tire width direction, and a high-hardness rubber layer having hardness higher than hardness of the bead base part and provided in at least a part of the bead inner-face part.
