摘要： [Object] A pneumatic tire 2 that allows achievement of reduction of rolling resistance without taking influence on a mass into consideration, is provided.[Solution] A profile OL of the tire 2 includes a ground-contact surface 46 and a pair of side surfaces 48. In the profile OL, a zone from a point PB to a point PW is formed by three arcs. The arcs are a first arc, a second arc that extends almost outward from the first arc in the radial direction, and a third arc that extends almost outward from the second arc further in the radial direction. A ratio of a radius R2 of curvature of the second arc to a radius R1of curvature of the first arc is greater than or equal to 1.45 and not greater than 3.26. A ratio of a radius R3 of curvature of the third arc to the radius R1 of curvature of the first arc is greater than or equal to 0.45 and not greater than 0.56. Each sidewall 8 of the tire 2 has a first recess 50a and a second recess 50b that are recessed inward from the side surface 48.

摘要： A method of manufacturing a pneumatic tire including forming a green case by cylindrically winding a tire component member which includes at least one layer of a carcass ply. The green tire is shaped by expanding the green case into a toroidal shape with the supply of a fluid into the green case so that the green case adheres to a tread ring arranged radially outside the green case. The green tire is subjected to vulcanization molding within a mold die. During the shaping of the green tire, the fluid is supplied in accordance with a pressure profile which changes in a stepwise manner. The pressure profile is set such that a former stage pressure which allows the green case to expand to 35% to 40% of a full expansion amount is set lower than a final stage pressure in a final stage.

摘要： [Object] A motorcycle tire, for an uneven terrain, which exhibits both impact absorption and handling stability is provided.[Solution] A tire 2 includes a pair of rubber reinforcing layers 14 disposed inward of a carcass 10 near ends, respectively, of a tread surface 16. A profile of the tread surface 16 is formed by: an arc C1 that is disposed at a center, and that projects outward in a radial direction; and a pair of arcs C2 each of which is disposed outward of the arc C1 in an axial direction and each of which projects outward in the radial direction. The arc C1 contacts with the arcs C2. A radius R1 of curvature of the arc C1 is less than a radius R2 of curvature of each arc C2. Outer ends 40 of the rubber reinforcing layers 14 are disposed outward of ends TE of the tread surface 16 in the radial direction. Inner ends 42 of the rubber reinforcing layers 14 are disposed inward of the ends TE of the tread surface 16 in the radial direction. The rubber reinforcing layers 14 are not disposed on an equator plane.
