<p>PROBLEM TO BE SOLVED: To provide a pneumatic tire suppressing a temperature rise while preventing separation in bead sections.SOLUTION: A pneumatic tire includes a carcass 13 toroidally extending between bead cores 12 buried in a pair of bead sections 11. The carcass 13 includes a folding-back section 13a winding the surroundings of the bead cores 12 from the inside of a tire width direction to the outside. Each of the bead sections 11 is disposed at prescribed intervals in a tire circumferential direction and includes a plurality of recesses 18 with opening sections 18a on a tire outer surface. In a tire radial direction, a distance D from the opening sections 18a to deepest sections of the recesses 18 is 30% to 80% of a distance of a perpendicular extending from the opening sections 18a to the folding-back section 13a.</p> |
