Title:
PNEUMATIC TIRE
Document Type and Number:
WIPO Patent Application WO/2018/225716
Kind Code:
A1
Abstract:
A reflection layer that reflects light is provided on the surface of a pneumatic tire, the reflection layer including a transparent small sphere group comprising a plurality of transparent small spheres. At least some of the transparent small spheres of the transparent small sphere group are configured such that incident light entering into the inside from outside of each of the transparent small spheres is reflected by an interface contacting the outside of the transparent small sphere, and is emitted as reflected light to the outside of the transparent small sphere. The transparent small spheres include a plurality of transparent small spheres A configured such that, commensurately with distance away from the transparent small spheres, the reflected light of the transparent small spheres A includes more non-retroreflective light separated from the light path of the incident light than retroreflective light. The angle difference of the light path of the non-retroreflective light of the transparent small spheres A is 2.0-2.5° from the light path of the incident light.
