摘要

Passenger car pneumatic tire includes a belt layer, and a belt cover layer formed by turning up the steel cord material in the tire circumferential direction on the outer peripheral side of the belt layer. The steel cord material is composed of a plurality of steel, the wire having a diameter less than the line 0.18mm, multiple strands twisted, respectively, and the twisted structure in the same direction as the twist direction of the wire a. Twist pitch of each of the strands is smaller than the twist pitch of the steel cord material, twist pitch of the strand is 1.0mm~2.1mm, twist pitch of the steel cord material is in 2.0mm~5.25mm .
