PURPOSE: A heavy duty vehicle tire with a pressure indicator is provided to easily perceive the amount of tread pressed by a load without using a ruler. CONSTITUTION: A heavy duty vehicle tire with a pressure indicator comprises a tread(1), sidewalls(2), and a bead portion(3). An indicator is formed by carving scales, which are deformed by pressure, on the sidewall side shoulder part of the tread. The scales include an axial indicator line(41) and oblique lines formed on both sides of the indicator line.
