Abstract:
A tire comprises a tread reinforcing layer comprising a cord-reinforced part formed by winding a rubberized cord strip with at least one reinforcing cord covered with a topping rubber. The cord-reinforced part includes a mesh part in which first inclined segments and second inclined segments of the rubberized cord strip are inclined to opposite directions with respect to the tire circumferential direction. The first inclined segments intersect the second inclined segments, leaving space parts each having a quadrilateral shape. The mesh part has a tire-equator-side first region, a tread-edge-side second region and a third region therebetween, wherein the space parts within the tire-equator-side first region each have an area A1, the space parts within the tread-edge-side second region each have an area A2, and the space parts within the third region each have an area A3 which is smaller than the area A1 and larger than the area A2.
