Pneumatic tire and method of manufacturing the same

摘要

A pneumatic tire comprising a silica - rich compound tread provided with an antistatic conductive rubber layer has improved safty based on durability and extrusion productivity. In this tire, the silica - rich compound rubber layer is divided at at least one portion in a width directional of the tire by a conductive rubber layer extended in a circumferential direction substantially over the whole thickness of said rubber layer. In this case, a thickness direction distance a in a width directional section of said rubber layer and an edge face length b of a divisional rubber layer consisting of said conductive rubber layer in a width directional section satisfy a relation formulated by the following expression, a < b.
