Tire and tread for a vehicle for agricultural use having reduced attack to leading faces of tread bars, at axially outer ends thereof, by stubble remaining after harvest, thereby reducing risk of chunking of axially outer ends of the bars. The tire and tread has a plurality of bars, a bar having, in any axial plane (Pxy) parallel to the axis of rotation, a leading profile and a trailing profile. The angle (A) of the straight line (T) tangential to the leading profile at a point (M) on the leading profile, with respect to an equatorial plane (P), increases continuously, from an axially outermost point (E) of the leading profile, when the axial distance (L) between the point (M) and the point (E) increases, the angle (A) reaches a maximum value (Am) at a point of inflection (I) of the leading profile, and the radius of curvature (R) at any point (M), positioned axially between the axially outermost point (E) and the point of inflection (I), is at least equal to 0.4 times the height of the bar.
