The present invention relates to preparation an article of manufacture, such as of a tire, via application of at least one partially pre-cured component. Tires are often prepared with pre-cured, pre-shaped components such as for example, application of pre-cured tread strips to a cured carcass as in the case of re-treaded tires. Thus precured tread and cured carcass are joined together using a cushion gum followed by heating the resulting assembly at an elevated temperature to cure the cushion gum. Such pre-cured component may also be, for example, a sidewall apex. In such cases, the pre-cured component is subjected to more heat than is necessary which may be detrimental for the component. This invention is directed to the use of a partially pre-cured component to prepare a tire assembly prior to the curing of the entire components of the tire assembly.

Tire preparation using partially pre-cured component

The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is quantitatively reinforced with silica and which, in turn, has a thin, integral, rubber outer cap on its outer surface which contains a quantitative amount of carbon black. In one aspect, said outer cap, sometimes referred to herein as an outer top cap, extends across the outer surface of the tread which is normally intended to be ground contacting and in an alternative aspect, the outer top cap extends only over the outer portion, namely the peripheral edges, of said tread surface intended to be ground contacting. The outer, carbon black reinforced, rubber tread top cap connects with at least one other carbon black reinforced rubber component of the tire in a manner to provide a path of reduced electrical resistance from said outer tread top cap to the bead portion of the tire carcass and, therefore, such a path from the vehicle to the road surface.
