  "textContent": "Provide is a technology in which a pneumatic tire for use as an on-road driving wheel has the water discharge efficiency enhanced without impairing the traction performance. Also provided is a pneumatic tire (100) for use as a driving wheel, including a tread having a directional pattern containing a plurality of width-direction grooves (11) and (12). Assuming that a half-width region of the tread, as measured from the tire equator (CL) to the tread-to-ground contact end (TE) along the surface of the tire in a cross section of the tread portion (1) in the width direction of the tire, is bisected into two regions that are referred to as the tread center portion (Tc) and the tread shoulder portion (Ts) respectively in this order from the tire equator (CL), the plurality of width-direction grooves (11) and (12) extend across the tread center portion (Tc), and have a pattern convex in the rotational direction of the tire.",
