[Object] A tire 2 that has quietness and durability improved without reducing steering stability, is provided.

[Solution] The tire 2 includes: a pair of beads 12; a carcass 14 that is extended on and between the beads 12 on both sides; and a pair of strips 24 that extend almost outward from the beads 12 along the carcass 14 in the radial direction. The beads 12 include cores 34, first apexes 36, and second apexes 38. The carcass 14 includes a carcass ply 44, and the carcass ply 44 includes a main portion 46 and turned-up portions 48. The turned-up portions 48 are disposed between the first apexes 36 and the second apexes 38. The turned-up portions 48 contact with the main portion 46 in portions radially outward of outer ends 42 of the first apexes 36. A position of an outer end 64 of each strip 24 is equal, in the radial direction, to a position Pb at which the maximum width is obtained, or the outer end 64 of each strip 24 is disposed radially inward of the position Pb at which the maximum width is obtained.

In an apex 34 of a tire 2, a reinforcing portion 48 is located inward of a main body 46 in an axial direction. When a position on an outer surface of the tire 2 at which position a height from a BBL is 14 mm is defined as a first point P1 and a position on the outer surface of the tire 2 at which position a height from the BBL is 20 mm is defined as a second point P2, the reinforcing portion 48 overlaps the first point P1 and the second point P2 in a radial direction. A loss tangent of the reinforcing portion 48 is equal to a loss tangent of the main body 46 or less than the loss tangent. A hardness of the reinforcing portion 48 is equal to a hardness of the main body 46 or greater than the hardness.

A modulus M50 (20 C.) at 50% deformation at 20 C. of the covering layer being in a range of from 0.4 MPa to 1.5 MPa, and the modulus M50 (20 C.) at 50% deformation at 20 C. of the covering layer and a modulus M50 (100 C.) at 50% deformation at 100 C. of the covering layer satisfying a relationship 1.0<M50 (20 C.)/M50 (100 C.)2.5.

Provided is a pneumatic tire in which fiber reinforced layers on an outer side of a steel reinforced layer in a width direction each include fiber cords arranged in one direction, the fiber cords being oriented to cross each other between layers, a radially outer end of one of the fiber reinforced layers being radially outward of a turned-up end portion of a carcass layer, a radially outer end portion of another one of the fiber reinforced layers being radially inward of the turned-up end portion and radially outward of a line segment (K). Radially inner end portions of the fiber reinforced layers are inward in the width direction of a line segment (J), and cord angles A and B of the fiber reinforced layers satisfy 20|A|45 or 70|A|90, and 20|B|45 or 70|B|90.

The pneumatic tire comprises a pair of bead cores, a pair of bead fillers disposed outward of the pair of bead cores in a tire radial direction, a carcass layer disposed folded around the bead cores and the bead fillers, and a steel chafer including an arranged plurality of steel cords, the steel chafer being disposed between the carcass layer and a rim engaging surface. A height Hs of an outer end portion of the steel chafer located outward of the bead fillers in a tire width direction and a rim flange height Hf have the relationship: 0.5Hs/Hf1.0, where the height is measured from a measuring position of a rim diameter.

Provided is a run-flat tire. A first bead filler is disposed on an outer circumferential side of a bead core, a second bead filler is disposed on an outer side in a tire width direction of a turned up portion of the carcass layer along the turned up portion of the carcass layer, and a thickness G on a first reference line of a side reinforcing layer, a thickness G1 on a second reference line of the side reinforcing layer, and a thickness G2 on a third reference line of the side reinforcing layer satisfy the relationships of 0.8GG11.0G and 0.5GG20.7G.

A motorcycle tire includes an insulation rubber layer disposed between a main body portion of a carcass ply and an inner liner layer in each axial half of the motorcycle tire. The insulation rubber layer extends from a first end on a tread portion side at least to a bead core. A sidewall portion includes an outermost end in the tire radial direction of an area of a tire outer surface of the sidewall portion contacting a standard rim. The tire outer surface has a side profile occupying 90% or more of a length in the tire radial direction between the tread edge and the outermost end from the tread edge. The side profile is a linear line or an arc concave axially inward and having a radius of curvature of 55 mm or more.
