摘要： The present invention relates to a pneumatic tire that may effectively discharge static electricity accumulated in a vehicle body while preventing separation between a conductive portion and a cap rubber in a tread portion. The pneumatic tire 1 comprises a tread rubber 2G comprising a cap portion 11 having a tread surface 2A, and an electrically conductive portion 12 having a first end exposed at the tread surface 2A and a second end connected with an electrically conductive tire element which is electronically communicated with a rim when the tire is mounted on the rim. The conductive portion 12 is formed of a strip wound body such that a rubber strip 14 is spirally wound. The rubber strip 14 comprises a wide strip 15 having an electrically conductive property, and a narrow strip 16 having a width smaller than a width of the wide strip 15 and disposed radially outward on the wide strip 15. The narrow strip 16 is made of the same rubber material as the cap portion 11 to which the narrow strip 16 is joined.

摘要： A conduction section of a base rubber section and a conduction section of a cap rubber section are reliably conducted with each other. Tread rubber is provided with a base rubber section formed by helically winding a first electrically non-conductive rubber strip, a cap rubber section formed by helically winding a second electrically non-conductive rubber strip, and a conduction section penetrating through the base rubber section and the cap rubber section and extending in the radial direction. The conduction section is composed of: a first electrically conductive winding section consisting of a first electrically conductive rubber strip which is wound within the base rubber section so as to be superposed on the first electrically non-conductive rubber strip; and a second electrically conductive winding section consisting of a second electrically conductive rubber strip which is wound within the cap rubber section so as to be superposed on the second electrically non-conductive rubber strip. An exposed surface section formed by the radial upper end of the first electrically conductive winding section and an exposed surface section formed by the radial lower end of the second electrically conductive winding section are tilted in different directions relative to the circumferential direction of the tire and intersect each other, and as a result, the first and second electrically conductive winding sections are conducted with each other at the position of the intersection.

摘要： A pneumatic tire excellent in high speed stability and turning ability is provided. In a band of a tire, a center portion located in an axial center has a helically wound structure in which a first band body including a first cord is wound. A shoulder portion located on an axial outside of the center portion has a meshed structure formed by a second band body including a second cord. The shoulder portion includes a plurality of first portions, a plurality of second portions and a plurality of third portions. Each first portion is inclined and extends from an axially inner end of the shoulder portion to an axially outer end of the shoulder portion. Each second portion is inclined in an opposite direction from the first portion and extends from the axially inner end of the shoulder portion to the axially outer end of the shoulder portion.
