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.
Claims10
A pneumatic tire in which at least a portion of an inner surface of a tire is pigmented with a fluorescent material, with at least one chromatic color in a relation of lightness V and saturation C according to JIS Z 8721-1977 of:
- V+C≧5 and V=1 to 9.5 and at C=1 or greater, or with an achromatic color at V=10, and wherein at least one layer having lightness V+saturation C according to JIS Z 8721-1977 of 5 or greater is interposed between the pigmented layer on the inner surface of the tire and a black rubber layer adjacent therewith.
A pneumatic tire in which at least a portion of an inner surface of a tire is pigmented with a fluorescent material, with at least one chromatic color in a relation of lightness V and saturation C according to JIS Z 8721-1977 of:
- V+C≧5 and V=1 to 9.5 and at C=1 or greater, or with an achromatic color at V=10, and wherein at least one barrier layer containing a polymer having an Solubility Parameter (18J1/2/cm3/2) or more is interposed between the pigmentation layer on the inner surface of the tire and a black rubber tire using at least one color thereby adding discriminating information.
A pneumatic tire-rim assembly in which at least portion of the surface of a rim is pigmented and the inner surface of a tire is also pigmented with a color related to a color pigmenting the rim, by a fluorescent material, a chromatic color in a relation of lightness V and saturation C according to JIS Z 8721-1977 of V+C≧5 and at V=1 to 9.5, C=1 or greater, or an achromatic color at V=10, wherein at least one barrier layer containing a polymer having an Solubility Parameter (18J1/2/cm3/2) or more is interposed between the pigmentation layer on the inner surface of the tire and a black rubber tire using at least one color thereby adding discriminating information.
A pneumatic tire-rim assembly in which at least a portion of a surface of a rim is pigmented and an inner surface of a tire is also pigmented with a color related to a color pigmenting the rim, by a fluorescent material, with at least one chromatic color in a relation of lightness V and saturation C according to JIS Z 8721-1977 of:
- V+C≧5 and V=1 to 9.5 and at C=1 or greater, or with an achromatic color at V=10, and wherein at least one layer having lightness V+saturation C according to JIS Z 8721-1977 of 5 or greater is interposed between the pigmented layer on the inner surface of the tire and a black rubber layer adjacent therewith.
