The present invention relates to a pneumatic tire tread having a protruding shape structure in a groove, and more particularly, to a cross-sectional shape of a groove in a pneumatic tire tread, which is capable of maintaining braking ability on a wet road surface and improving rolling resistance performance even if wear of the tire progresses, by forming the protruding parts in such a way that a width of the groove is partially increased toward an inside from an outside in a radial direction of the tread.In a pneumatic tire tread having a protruding shape structure in a groove according to the present invention, the pneumatic tire tread includes a groove structure having grooves formed in a circumferential direction of the tire, and at least one pair of protrusion parts which are formed in an abutting form symmetrical vertically with respect to a central axis of the groove, wherein the protrusion parts provided in the groove are formed in such a way that a distance between lower portions thereof is increased toward an inside in a radial direction of the tread, thus to have the same shape as the groove which does not have the protrusion part as wear thereof progresses.
