摘要： A tread (1) for a heavy-duty vehicle tyre, having a tread surface (10) and an undulating groove (2) formed therein, having, when new, external cavities (21) open onto the tread surface (10) and internal cavities (22) entirely situated there-beneath when new, these cavities (22) connected to cavities (21) by linking cavities (23), each external cavity (21) intersecting the tread surface (10) along a corner edge contour delimiting an opening (210) having two end regions (A1, A2) and a surface area Se measured on the tread surface (10). In each end region (A1, A2) at least one thin blade (41, 42) of rubbery material is formed which is secured to at least one of the walls delimiting the undulating groove to reduce the surface area of the opening (210) of each external cavity (21) viewed from the tread surface (10) when new.

摘要： The tread has a wearable thickness of material EMU and has raised elements delimited by grooves. Each solid part has a contact face and a cavity with a depth greater than 50% of the wearable thickness. Each cavity opens onto the contact face when new and is delimited by a wall surface and a bottom surface. Each wall surface deliminates a cavity that intersects the contact face along a corner edge contour that has a geometry that has a major axis which is at least 1.5 times the length of a minor axis when new. For any tread surface down to a predefined wear level, the level is at most 30% of the wearable thickness of material EMU, and the angle between the major axis and the circumferential direction is between 0 and 40 degrees. After the wear level, the angle is greater than 40 degrees.

摘要： A groove of tire thread having a plurality of first and second portions, each delimited by facing walls spaced apart by a maximum width measured at the tread surface and approaching one another such that, at a depth between 20 and 80% of the total depth they are spaced apart by a width less than the maximum width or facing walls spaced apart by a minimum width measured at the tread and diverge from one another such that, at a depth between 20% and 80% of the total depth of the groove, they are spaced apart from one another by a width greater than the width. A plurality of first and second portions of groove so as to form a continuous passage between all the portions of groove in order to allow liquid to flow in the groove regardless of the level of wear.

摘要： 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.

摘要： A tire tread including a tread surface adapted to come into contact with a road surface has at least one main groove that, when new, opens onto the tread surface of the tread, this main groove having a maximum depth. The main groove includes a plurality of first groove portions and a plurality of second groove portions, the first and second groove portions being arranged alternately such that a first portion is followed by a second portion. Each first groove portion has a width that decreases with wear, and each second groove portion has a width that increases with wear.
