A high-transverse-curvature tire (1), in particular for mounting onto the rear wheel of motor-vehicles, comprises a tread band (8), coaxially extended around a belt structure (6), wherein a plurality of rubber blocks (10), defined between a plurality of grooves (1 1) extending along a direction substantially transverse to the tire running direction (D), are formed which grooves comprise a bottom (12) connected to opposite inlet (13) and outlet (14) sidewalls. In an equatorial zone (E) of the tread band (8), the inlet wall (13) of the grooves (11) is inclined with respect to the bottom (12) of the same towards the tire rolling direction, and forms an angle (alpha) of from 50° to 80° with respect to a plane (pi) tangent to the bottom (12).
