The invention relates to a method of manufacturing a tire having a colored sidewall. The method comprises disposing a strip of a colored rubber compound circumferentially about the external surface of the sidewall region of the tire in its uncured state, placing the uncured tire in a tire curing mold with the strip exposed to direct contact with the mold, providing the mold with circumferential recesses at both sides of the rubber strip and letting the strip slightly overlap with the recesses in the radial direction of the tire, curing the tire whereby circumferential side parts of the strip flow into the recesses to form circumferential protrusions in the strip, removing the tire from the mold, and removing the protrusions at least partially. The invention further relates to a tire obtained with the method.
