摘要： A pneumatic tire for off-road vehicles comprising a multi-layered carcass and a breaker superimposed about the carcass. The carcass is composed of rubberized ply layers each containing cords formed of organic fiber and inclined at an angle of 23.degree. to 45.degree. with respect to the equatorial line of the tire. The cords of approximately one-half of the carcass plies extend in an opposite direction to the cords associated with the remaining plies. The breaker is composed of at least one rubberized layer each containing reinforcing elements formed of a plurality of filaments whose material having a tensile strength of at least 140 Kg/mm.sup.2, the reinforcing element being inclined at an angle which is not larger than a selected angle of the carcass cord by at least 5.degree. and not smaller than the selected angle of the carcass cord by at least 15.degree.. At least one rubberized layer of the breaker disposed near the tread is extended over a width of 40 to 60% of the tread width.
