HEAVY DUTY TIRE AND PRODUCTION METHOD FOR HEAVY DUTY TIRE

A contour CL of a carcass includes a curved portion and an inversely curved portion . A boundary between the curved portion and the inversely curved portion is an inflection point PV. A part or an entirety of the curved portion is represented by a first arc. A part or an entirety of the inversely curved portion is represented by a second arc. The first arc and the second arc are tangent to each other at the inflection point PV. A ratio (X/W) of a distance X in an axial direction to a distance W in the axial direction is not less than 70% and not greater than 85%. A ratio (Y/H) of a distance Y in a radial direction to a distance H in the radial direction is not less than 15% and not greater than 22%.
