Abstract: Particular embodiments of the present invention comprise a tire tread having a length and a width. The tread further includes a thickness bounded by a top side for engaging a surface during tire operation and a bottom side. Moreover, the tread includes a top side void arranged along the top side of the tread and defining a wall extending depthwise within the tread thickness from the top side. Finally, the tread includes a projection extending outwardly from the wall and to a terminal end of the projection, the projection having a top side and a bottom side defining a thickness of the projection, the projection also having a length extending longitudinally along a length of the wall, the length of the wall extending perpendicular to a depthwise direction of the tread thickness. Further embodiments comprise a tire including a tire carcass and a tread as described in the preceding paragraph.

Abstract: The invention relates to an off-road tire comprising a composition based on at least one filler, a crosslinking system, from 50 to 80 parts by weight, per hundred parts by weight of elastomer (phr), of at least one isoprene elastomer and from 20 to 50 phr of at least one polybutadiene having a high vinyl content, the total content of isoprene elastomer and of polybutadiene having a high vinyl content being within a range varying from 85 to 100 phr.
