A method for displaying an image of a surface of a tire includes: a step of taking an image of a surface (1a) of a tire (1) formed with a mark having a protrusion and a recess; a step of acquiring waveform data from the taken image of the surface; a step of creating a histogram from the waveform data; a step of determining, based on the histogram, a first bin threshold to separate a surface luminance of the protrusion of the mark from a surface luminance of the surface other than the protrusion, and a second bin threshold to separate a surface luminance of the recess of the mark from a surface luminance of the surface other than the recess; and a step of displaying the image of the surface of the tire including the mark on a screen (11a) by representing a region equal to or higher than the first bin threshold, a region lower than the first bin threshold and higher than the second bin threshold, and a region equal to or lower than the second bin threshold in the histogram in three attributes of color.
