PNEUMATIC TIRE

摘要

An objective of the present invention is to provide a pneumatic tire whereby primarily rolling resistance is minimized and noise is minimized. This pneumatic tire tread rubber (5) comprises: a cap part (50) which is formed of non-conductive rubber and configures a grounding surface; a base part (51) which is disposed on the inner side of the cap part (50) in a tire radial direction (RD); and conductive parts (52) which are disposed in both of a pair of lateral end parts which are at ends of the cap (50) in a tire width direction, traverse the inner part of the cap (50) while avoiding a location which covers the grounding surface, and form shapes which connect the grounding surface with the bottom surface (50b) of the cap part (50) in the tire meridian cross-section. The conductive parts (52) are provided with extended sites (52b) which branch off outward to the tire width direction (WD) from conductive paths (52a) which connect the grounding surface with the bottom surface (50b) of the cap part (50). The conductive parts (52) are formed of a conductive rubber which has different rubber hardness from the non-conductive rubber which forms the cap part (50).
