Abstract: Provided is a pneumatic tire with a surface provided with a reflective layer that reflects light, the reflective layer including a transparent globule group composed of transparent globules. At least some of the transparent globules are each configured to reflect incident light incident into the transparent globule from outside, at an interface with the outside of the transparent globule, and to emit the light to the outside of the transparent globule as reflected light. The transparent globules are each configured to cause the reflected light to include more amount of non-retroreflected light than retroreflected light, the non-retroreflected light moving further away from an optical path of the incident light according to a distance from the transparent globules, being increased. The transparent globules each have an optical path of the non-retroreflected light with an angle difference of from 2.0 degrees to 2.5 degrees from the optical path of the incident light.
