Motorcycle tire for running on rough terrain

A motorcycle tire for running on rough terrain comprising

• a tread portion provided with a plurality of blocks defining a unidirectional tread pattern for which a tire rotational direction is specified,
• the blocks including a T-sided block,
• the T-sided block having a top surface, a heel-side sidewall surface extending radially inwardly from a heel-side edge of the top surface, and a toe-side sidewall surface extending radially inwardly from a toe-side edge of the top surface, wherein
• in a cross section perpendicular to the top surface and parallel to the tire circumferential direction, the angle α of inclination of the heel-side sidewall surface towards the heel-side is, at the heel-side edge, in a range of from 0 to 15 degrees with respect to the normal direction to the top surface,
• the toe-side sidewall surface comprises
• a radially outer region extending radially inwardly from the toe-side edge so as to have a height of from 20 to 55% of the height of the T-sided block, and
• a radially inner region extending radially inwardly from the radially outer region,
• said radially outer region is inclined toward the toe-side at an angle β of from 20 to 45 degrees with respect to the normal direction to the top surface at the toe-side edge,
• the radially inner region has
• a central part extending at the same angle β as the radially outer region,
• a pair of lateral parts located one on each side of the central part and having at an inclination angle γ toward the toe-side in a range of from 0 to 15 degrees with respect to the normal direction, and
• a pair of stepped parts extending between the lateral parts and the central part in a direction crosswise to the toe-side edge.
