Tires having white sidewalls are very popular in the United States and Canada. This invention discloses a process for preparing such tires having decorative appliques thereon. By practicing the process of this invention, tires having better uniformity can be built at lower costs than when standard tire building techniques are utilized. This invention specifically relates to a method of preparing a pneumatic rubber tire having a decorative design on the sidewall thereof which comprises (a) applying the decorative design to the sidewall of a cured tire and (b) binding the decorative design to the sidewall by the application of heat and pressure; wherein the decorative design is comprised of from about 25 weight percent to about 75 weight percent syndiotactic 1,2-polybutadiene or blends of SPED having melting points which are within the range of about 70°C to about 160°C and from about 25 weight percent to about 75 weight percent of at least one polydiene rubber which is blended with said syndiotactic 1,2-polybutadiene, at least one pigment or colorant, sulfur, and zinc oxide.
