Abstract
Abstract In a pneumatic tire according to the present invention, at least a portion for an inner surface of a tire is pigmented with a fluorescent material, with a chromatic color of specified lightness and saturation or with an achromatic color at V=10. Further, in a tire-rim assembly according to the present invention, at least a portion for an inner surface of a tire is pigmented with a fluorescent material, with a chromatic color of specified lightness and saturation or with an achromatic color at V=10 as the discriminating information for rim assembly, and at least a portion for the surface of a rim assembled with the tire is pigmented with a color related to the color pigmenting the tire.
