Fig. 9.
Temperature profile of tire. Corresponding to L1 in Fig. 8., 1px is about 6.2 mm and the ambient temperature is 10 °C. The horizontal axis unit px is the unit pixel point of the picture, and the horizontal axis from 0px to 350px corresponds to the length of the temperature measurement line from A to B, the same as the following figures. Due to the small differences in temperature measurement distances, the actual distance represented by 1px varies from picture to picture and is labelled in the caption.
