Abstract

Abstract A method of producing a tire having on each sidewall thereof a band or bands of fluorescent colors which will not be detached from the tire body and remain fresh over a prolonged period of time and which are effective in decorating the tire particularly in the nighttime, said method comprising constructing the tire body with an outer rubber layer and an inner rubber layer having a color-developing effect and bonded integrally to said outer rubber layer, grinding each sidewall of the tire body by a grinder to form therein an annular groove or grooves and forming in said annular groove or grooves a laminate of an elastic undercoating layer of transparent anchoring agent and a fluorescent layer containing an ultraviolet ray-absorbing compound or a laminate of said undercoating layer, a fluorescent layer and a transparent top-coating layer containing the ultraviolet ray-absorbing compound.
