<P>PROBLEM TO BE SOLVED: To provide a pneumatic tire that can reduce rim sliding by surely wiping off a lubricant. <P>SOLUTION: A protrusion 26 is formed in a bead heel part 22. The protrusion 26 is one protrusion that projects from the surface of the bead heel part 22 and extends like the ridge, and formed over the circumference of the tire circumferential direction. A recessed groove 28 is formed in the bead toe 21 side of the protrusion 26, that is, the tire equatorial plane side in the tire axial direction of the protrusion 26. The recessed groove 28 is a groove formed to become concave from the surface of bead heel part 22, and formed along the protrusion 26. <P>COPYRIGHT: (C)2013,JPO&INPIT |
