Abstract:
A pneumatic tire having an equatorial plane and a tread, the tread having a tread width measured between first and second lateral edges, a continuous circumferentially extending center rib aligned with said equatorial plane and first and second rows of elongated tread elements equally spaced from said center rib so as to form two continuous circumferential grooves, one on each side of said center rib, the tread elements in the first and second rows being connected via tie bars extending between each adjacent pair of tread elements, the center rib and the first and second rows of tread elements comprising from 30% to 50% of the tread width and defining a working rib portion of the tread wherein the net-to-gross ratio of the working rib portion is between 50% and 55% and the net-to-gross ratio of a remaining portion of the tread is between 51% and 53%, the elongated tread elements in the first and second rows have a circumferential length at least four times their lateral width, and a void capacity of the tread increases from the equatorial plane to respective lateral edges of the tread.
