ABSTRACT:
A white sidewall band for radial ply tires consisting of upstanding wall areas extending axially outward from surrounding sidewall areas and having white rubber disposed radially across the width of the band and recessed axially inward from one wall area to the other. Sidewalls of this type can be made using buffing stones having buffing surfaces of convex cross-section, and result in white sidewalls protected from dirtying during transportation, storage, and the like without introducing structural weakness in the sidewall area.
