摘要 |
<p>The present invention relates to a tire (1) having a rubber tread (2) of a lug and groove configuration and of a co-extruded cap/base construction; wherein the tread cap (6) is of a rubber composition which contains carbon black and is thereby of a black color; wherein a visible surface (14) of at least one groove (15) is of a rubber composition exclusive of carbon black and is of a non- black color and wherein said visible non-black colored rubber composition is a rubber layer (7) which underlies said tread cap. Said visible non-black colored rubber is exclusive of any appreciable portion of, and preferably exclusive of, the surface (16) of said tread lugs (12) intended to be ground-contacting. In one aspect of the invention, said non-black colored rubber composition contains an amorphous precipitated silica reinforcement, preferably a pre-hydrophobated precipitated silica. In another aspect of the invention, said non-black colored rubber composition, and alternately, carbon black containing black colored rubber compositions adjoining said non-black colored rubber composition, is comprised a blend of at least one diene based elastomer and a brominated copolymer of isobutylene and p-methylstyrene together with an organo phosphite. <IMAGE></p> |
