Zusammenfassung:	Method for making a tire whose white sidewall portion is created by, selectively, providing a circumferential groove in the molded tire, buffing the surfaces of the groove, placing an adhesive in the groove, heating the tire about 138 DEG C. to dry the adhesive, bringing the tire temperature to about 100 DEG C. and, while rotating the tire with the groove in a substantially horizontal plane, directing a stream of white polyurethane stock into the groove by means of an applicator which is formed to direct the stock in differing volumes into the bottom of the groove and laterally against its corners and sides; the white sidewall strip so formed has the shape of a concave meniscus.
