The invention relates to an aqueous paint composition which is particularly useful for protecting the white sidewalls of tires from staining and scuffing. This paint is comprised of: (a) an aqueous mixture, including polyvinyl alcohol and an ethylene/vinyl acetate copolymer, wherein the weight ratio of the polyvinyl alcohol to the vinyl acetate-ethylene copolymer is within the range of about 85:15 to about 60:40; and (b) a silicon emulsion in an amount sufficient to provide increased scuff resistance for a coating prepared from the composition. Preferably, the aqueous composition includes a polysiloxane agent for increasing scuff resistance and high humidity resistance. This invention further reveals a pneumatic tire having a white sidewall or white lettering thereon wherein the white sidewall or white lettering is coated with a protective layer to protect the white sidewall or white lettering, said tire being characterized by the coating thereon being comprised of greater than about 15 percent by weight polyvinyl alcohol, greater than about 65 percent by weight of a vinyl acetate-ethylene copolymer, greater than about 0.5 percent by weight plasticizer and a sufficient amount of silicon for increasing the scuff resistance of the coating.
