Patent ID: 8167015

Claim:
A method of manufacturing a pneumatic tire, comprising steps of: a tread forming step forming an electrically non-conductive tread rubber; and a sidewall forming step forming an electrically conductive sidewall rubber, wherein the tread forming step includes: a first step forming an electrically non-conductive tread rubber that constitutes an outer periphery portion of the tread; and a second step forming, on the tread surface, an electrically conductive layer that extends continuously along a circumferential direction of the tire while alternately passing through a plurality of first positions that are located on the tread surface inside of a ground contact end of the tread surface as viewed in a width direction of the tire and a plurality of second positions that are located outside of the ground contact end of the tread surface as viewed in the width direction of the tire, the second positions being in contact with the sidewall rubber, and the sidewall forming step includes a step to dispose an outer end of the sidewall rubber as viewed in a tire-diameter direction, on an imaginary extension line or at a distance that is outside of the imaginary extension line as viewed in a tire-diameter direction, said imaginary extension line extending outwardly toward the sidewall rubber in a tire width direction from a point at a 15% depth of wear limit in a shoulder portion of the tire along the tread surface, as well as at a point that is located outside of the ground contact end of the tread surface as viewed in a width direction of the tire.
