Abstract
The pneumatic tire of the present invention includes two or more inclined belt layers each formed of a rubberized layer of belt cords extending so as to intersect each other between layers, and one or more circumferential belt layers, each disposed on a tire radial inner side of the inclined belt layers and formed of a rubberized layer of reinforcement cords extending in the tire circumferential direction or extending at an inclination angle of 5° or less with respect to the tire circumferential direction. An elastic modulus E1 in a high strain region of an extracted cord of the reinforcement cords is 30 GPa to 80 GPa.

A pneumatic tire comprising:
- two or more inclined belt layers each formed of a rubberized layer of belt cords extending so as to intersect each other between layers;
- and
- one or more circumferential belt layers, each disposed on a tire radial inner side of the inclined belt layers and formed of a rubberized layer of reinforcement cords extending in the tire circumferential direction or extending at an inclination angle of 5° or less with respect to the tire circumferential direction,
- wherein an elastic modulus E1 in a high strain region of an extracted cord of the reinforcement cords is 30 GPa to 80 GPa.
