<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire capable of improving fuel economy. <P>SOLUTION: The pneumatic tire 1 has a fin 9 for turbulence generation provided on a surface of a tire side S. Additionally, a center line ML of the fin 9 has an inflection point P which connects adjacent line segments to each other at a bend angle θ satisfying the inequality of 10 [deg]≤θ≤170 [deg], and is set protrusive in the circumferential direction of the tire. Thus, since the center line ML of the fin 9 has the inflection point P, the overall length of the fin 9 becomes long. Consequently, a turbulence generation effect of the fin 9 during the rotation of the tire is enhanced. <P>COPYRIGHT: (C)2013,JPO&INPIT |
