Patent attributes
A pneumatic tire includes a tread portion provided with a tread pattern with a designated rotational direction. The tread pattern includes a plurality of V-shaped main inclined grooves that protrude toward the rotational direction and extend from one tread edge to the other tread edge, a pair of connecting grooves disposed both sides of a tire equator between the circumferentially adjacent main inclined grooves, and a center block divided among the circumferentially adjacent main inclined grooves and the one pair of connecting grooves. The center block has a trapezoidal-like shape that comprises a laterally extending leading edge and a laterally extending trailing edge having an axial length larger than that of the leading edge.
