Provided are: a rubber-cord composite that improves the strength and modulus of an entire belt layer without causing any problem attributed to reinforcing cords and can thereby further improve the durability of a tire as compared to conventional tires; a tire reinforcing member; and a tire using the same. The rubber-cord composite is used for a spiral cord layer of a tire reinforcing member that includes a core-material cord layer 2 and a spiral cord layer 3. A reinforcing cord 3a is singly or plurally arranged in parallel and coated with a rubber. The reinforcing cord includes a nonmetallic fiber. When the modulus, end count, thickness, specific gravity, final twist number and total fineness of the reinforcing cord are defined as A, B, C, D, E and F, respectively, a modulus X represented by X = A×B is 1,000 GPa or higher; a cord interval Y represented by Y = (50 - B × C)/B is 0.1 mm to 5 mm; and a twisting coefficient of the reinforcing cord represented by Z = tanθ = E × √(0.125 × F/D)/1,000 is higher than 0.3.
