The object is to provide a radial tire for a construction vehicle having an extended life-time by suppressing occurrence of separation failure at edges of respective belts without lowering cut resistance. A radial tire 10 is provided with a steel belt layer 14 at the tire radial outer side of a steel radial carcass 12. The steel belt layer 14 includes two reinforcement belts 18, two main cross belts 20, and two protective belts 22 in this order. The steel cords of the outermost side protective belt 22U constituting the tire radial outermost side of the protective belts 22 are arranged in a same direction of the steel cords constituting the widest cross belt. The belt width of the outermost side protective belt 22U is wider than the widest main cross belt 20L of the main cross belts 20, and is within a range of 75 to 90% of the tire width. |
