PROBLEM TO BE SOLVED: To improve the durability of a tire by restraining the rubber cracks at the end section of a crossing reinforcing layer from developing and the rubber between the layers at the crossing section of the reinforcing elements positioned at each position in a reinforcing layer constituting the crossing reinforcing layer from cracking in the tire with the crossing reinforcing layer. SOLUTION: This tire has a reinforcing layer 3 of at least two layers comprising rubber coated reinforcing elements 2, which are arranged in parallel with each other. At least two layers of the reinforcing layer 3 comprise a crossing reinforcing layer 1, in which the reinforcing elements 2 are arranged in parallel with each other as a bundle 4 of reinforcing element units comprising at least two reinforcing elements 2. 100% modulus M<SB>100</SB>of a coated rubber 13 constituting each reinforcing layers 3a and 3b wherein the arrangement interval d1 between reinforcing elements 2a1 and 2a2 constituting the same reinforcing bundle 4 is narrow, and the arrangement interval d2 between reinforcing bundles is broad is in the range of 1.0 to 6.0 MPa at a room temperature, and rubber thickness t between the reinforcing elements 2a and 2b is characterized by being in the range of 0.2 to 1.2 times the outer diameter D of the reinforcing elements 2a and 2b.
