A pneumatic radial tire for heavy loads that prevents occurrence of a side cut due to a projection while decelerating spread of a cut damage to a tire inner surface. In a widthwise cross section of the tire, angle α satisfies a relation 0<α≰30° that a line joining an intersection between a virtual line and a tire outer surface and a maximum tire width position forms with respect to a radial line segment, the virtual line passing through a maximum carcass width position that is parallel to a tire axis line. An angle β satisfies a relation 0≰β<30° that a line joining the maximum tire width position and a turnoff point forms with respect to the radial line segment, and a reinforcing rubber is disposed between a body portion and a turn-up portion of the carcass.
