ABSTRACT:
A heavy duty pneumatic tire is disclosed. This tire has a tread pattern comprising projections arranged independently and spaced apart from each other in the circumferential direction of the tire and transverse grooves for separating the projections one from the other. The projection is provided with a buttress nestling from the bottom of the transverse groove along the groove wall thereof and being partly united with the groove wall. The buttress extends toward the direction of the transverse groove at a height lower than the surface level of the projection and is arranged so as to produce a narrow gap between the opposed adjacent buttresses or between the buttress and the opposite projection.
