TIRE HAVING SIDEWALL WITH INTEGRAL COLORED MARKING COMPOSITE

摘要

This invention relates to a tire with a rubber sidewall having at least one layered rubber composite integral with a portion of its outer surface as a means of visibly identifying the tire. The layered composite is an integral composite in a sense of being comprised of a base rubber layer and a contrastingly colored marking rubber layer being partially pre-cured together prior to application to the outer surface of an uncured rubber sidewall. The integrally layered composite and tire rubber sidewall are integral in a sense of being co-cured together with the surface of the base rubber layer facing the rubber sidewall surface. The base rubber layer is a black colored carbon black reinforced rubber layer. The marking rubber layer is of color which contrasts with the black color of the base rubber layer. The base layer is a protective rubber layer which extends beyond the peripheral edges of said marking layer and is protective in a sense of inhibiting, or retarding, discoloring materials from migrating through it to the contrastingly colored marking layer.
