Abstract
A tread includes a center main groove extending in a tire circumferential direction, and a shoulder main groove; in at least one of the center main groove and the shoulder main groove, an inclination angle of a groove wall on an outer side in a tire axial direction is smaller than an inclination angle of a groove wall on an inner side in the tire axial direction; each of beads includes a bead core and a bead filler extending outward from the bead core in a tire radial direction; and a steel reinforcement layer including steel cords is placed outward of the bead filler in the tire axial direction.

A pneumatic tire, comprising:
- a tread,
- a pair of sidewalls arranged on opposite sides of the tread,
- a pair of beads arranged inward of the sidewalls in a tire radial direction, and
- a carcass ply extended between the pair of beads, wherein the tread includes a center main groove extending in a tire circumferential direction, and a shoulder main groove placed outward of the center main groove in a tire axial direction, and extending in the tire circumferential direction,
- in at least one of the center main groove and the shoulder main groove, an inclination angle of a groove wall on an outer side in the tire axial direction, relative to a normal perpendicular to a profile surface of the tread, is smaller than an inclination angle of a groove wall on an inner side in the tire axial direction, relative to the normal perpendicular to the profile surface of the tread,
- each of the beads includes a bead core and a bead filler extending outward from the bead core in the tire radial direction, and
- a steel reinforcement layer including steel cords is placed outward of the bead filler in the tire axial direction.
