In addition, the grounding tread (5) has a widened section (51), where the sectional area of the widened section is increased toward the contact surface with the belt layer (14), at the contact part with the belt layer (14). Also, the widened section (51) of the grounding tread (5) has a profile that protrudes in the tire width direction.</p> |
