Abstract
A pneumatic tire includes a pair of bead cores; a pair of bead fillers that are connected to the pair of bead cores; a carcass ply that is suspended between the pair of bead cores; a side wall rubber that is arranged on a tire-outer-surface-side of the carcass ply and constitutes a tire outer surface; a chafer layer that is turned from a tire-inner-surface-side to the tire-outer-surface-side around the bead cores and the bead fillers and rolled up on an outer surface of the carcass ply; and a pair of support rubbers that are located between the side wall rubber and the carcass ply and arranged so as to hold a rolled-up end of the chafer layer from both sides in a tire width direction. A modulus values of the pair of support rubbers are higher than a modulus value of the side wall rubber.

A pneumatic tire comprising:
- a pair of bead cores;
- a pair of bead fillers that are connected to the pair of bead cores and extend to an outer-diameter-side in a tire radial direction;
- a carcass ply that is suspended between the pair of bead cores;
- a side wall rubber that is arranged on a tire-outer-surface-side of the carcass ply and constitutes a tire outer surface;
- a chafer layer that is turned from a tire-inner-surface-side to the tire-outer-surface-side around the bead cores and the bead fillers and rolled up on an outer surface of the carcass ply;
- and
- a pair of support rubbers that are located between the side wall rubber and the carcass ply and arranged so as to hold a rolled-up end of the chafer layer from both sides in a tire width direction,
- wherein a modulus values of the pair of support rubbers are higher than a modulus value of the side wall rubber.
