Abstract: An agricultural tire includes a toroidal tire structure containing vulcanized rubber in an amount of about 90 percent or more by weight. The tire structure may have one or more performance enhancing features, including high strength plies. The high strength plies contain cords that are formed of yarns, including polyamide yarns, and have individual cord tensile strengths within a range of about 400 N to about 700 N. The performance enhancing features further include circumferential belt plies having cords at angles of about 74 degrees or more from an axial direction.
