A pneumatic tire having a reinforcing belt which includes a first ply of cords formed from a synthetic material having a high modulus of elasticity and a second ply of metallic cords. The first ply has a width substantially equal to the width of the tread of the tire. The second ply has a width between one-fourth and three-fourths of the width of the tread. The second ply reinforces the median region of the tread. Each cord of the first ply intersects the median equatorial plane of the tire at a first angle of from 14 DEG to 30 DEG ; each cord of the second ply intersects the median equatorial plane of the tire at a second angle of from 22 DEG to 32 DEG . The second angle is opposite in direction from the first angle. At least one strip of cords formed from a synthetic material having a low modulus of elongation overlaps an edge region of the second ply. The foregoing abstract is not to be taken as a complete exposition of the present invention. |
