A radial ply pneumatic tire (10) has a tread portion (12) extending circumferentially thereabout. The tread has a plurality of circumferentially extending grooves (36,38,40,42) therein. The axially outermost circumferential grooves (36,42) communicate with one another through two series of crisscrossed curved grooves (44,46), with the grooves of each series inclined in opposite directions across the tread, Drainage grooves (110) extend from the axially outermost circumferential grooves (36,42) to the nearest axial edge (TE1, TE2) of the tread in a substantially axial direction. The tire exhibits good handling at high speeds on both wet and dry pavement, while also providing better snow traction than known high performance tires.
