Pneumatic tire

A pneumatic tire comprising:

• a tread;
• a pair of sidewalls;
• a pair of beads;
• a carcass;
• and
• a pair of reinforcing layers, wherein
• the sidewalls extend almost inward from ends, respectively, of the tread in a radial direction,
• the beads are disposed inward of the sidewalls, respectively, in the radial direction,
• the carcass is extended on and between one of the beads and the other of the beads along inner sides of the tread and the sidewalls,
• the reinforcing layers are disposed outward of the carcass in an axial direction,
• the beads include cores, and apexes that extend outward from the cores, respectively, in the radial direction,
• the reinforcing layers extend outward from portions near outer ends of the apexes along the carcass in the radial direction, and each reinforcing layer is tapered outward from an inner portion thereof in the radial direction,
• when a reference position is defined as a position on an outer surface of the tire, the position corresponding to a radially outer edge of a contact surface on which the tire and a rim contact with each other when the tire is mounted on the rim and inflated with air to a normal internal pressure,
• each of the outer ends of the apexes is disposed inward of the reference position in the radial direction, and
• an inner end of each reinforcing layer is disposed inward of a position that is distant from the outer end of a corresponding one of the apexes by 10 mm in a radially outward direction.

A pneumatic tire comprising:

• a tread;
• a pair of sidewalls;
• a pair of clinches;
• a pair of beads;
• a carcass;
• a pair of strips;
• and
• a pair of support layers, wherein
• the sidewalls extend almost inward from ends, respectively, of the tread in a radial direction,
• the clinches extend almost inward from ends of the sidewalls, respectively, in the radial direction,
• the beads are disposed inward of the clinches, respectively, in an axial direction,
• the carcass is extended on and between one of the beads and the other of the beads along inner sides of the tread and the sidewalls,
• the beads include:
• cores;
• and apexes disposed outward of the cores in the radial direction,
• the carcass includes a carcass ply, the carcass ply is turned up around the cores from an inner side toward an outer side in the axial direction, and the carcass ply includes a main portion and turned-up portions by the carcass ply being turned up,
• the strips extend along the main portion in the radial direction in portions radially outward of the apexes, respectively,
• the support layers are disposed outward of the strips, respectively, in the axial direction, and
• when a reference position is defined as a position on an outer surface of the tire, the position corresponding to a radially outer edge of a contact surface on which the tire and a rim contact with each other when the tire is mounted on the rim and inflated with air to a normal internal pressure,
• an outer end of each apex is disposed inward of the reference position in the radial direction, and each support layer extends almost outward from a portion near the reference position in the radial direction.
