摘要： A method for displaying an image of a surface of a tire includes: taking an image of a surface of a tire formed with a mark having a protrusion and a recess; acquiring waveform data from the taken image of the surface; creating a histogram from the waveform data; determining, based on the histogram, a first bin threshold to distinguish a surface luminance of the protrusion of the mark, and a second bin threshold to distinguish a surface luminance of the recess of the mark; and displaying the image of the surface of the tire including the mark on a screen 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.

摘要： A tire testing machine is for testing a tire, comprising a free roller section configured to include a plurality of rollers having an endmost roller disposed downstream of a lubricator in a conveying direction and farthest from a predetermined reference position, the endmost roller being disposed such that a horizontal distance from the reference position is equal to or greater than a radius of a largest of a plurality of tires set in advance as objects of application of a lubricant.

摘要： A tire testing device having a rotary drive unit that rotationally drives a tire; a load drum that has an outer peripheral surface that can come into contact with the tire being rotationally driven; a drum support mechanism that supports the load drum and relatively moves the load drum such that the tire and the outer peripheral surface of the load drum come into contact and separate; a shape sensor that detects a surface shape of the tire being rotationally driven; a drive control unit that controls the operation of the rotary drive unit, the drum support mechanism, and the shape sensor; a registration unit that stores information related to the tire test; and an input reception unit that receives, and registers, in the registration unit, information related to the tire test entered by a user prior to the tire test being conducted.
