摘要： The present invention is directed towards speckled tire treads for tires. Specifically, the speckled tire tread includes a primary tread compound that serves as a matrix in which is distributed discrete particles of one or more secondary tread compounds, at least one of the compounds is a different color than the other tread compound(s) so as to be visually distinguishable. For example, the primary tread compound may include carbon black pigment and be black in color while the secondary tread compound can include one or more pigments to provide the particles with non-black color. Thus, the colored particles have a visually distinguishable color from that of the primary tread composition. Additionally, at least a portion of the particles may be situated for viewing on a running surface of the tire tread so that a subject can visually distinguish between the compounds, and such observed compounds may provide a different tire performance characteristic(s).

摘要： The invention relates to a tire having a circumferential tread of a cap/base configuration composed of an outer tread rubber cap layer with a running surface of the tread and an underlying tread rubber base layer, wherein said tread cap layer is composed of two longitudinal adjacent zones, namely a primary tread cap zone and a minor lateral outboard control element (zone). The primary tread cap zone and the lateral outboard tread cap element provide a significant gradation of cold dynamic storage moduli (G′) at −25° C. and hot tan delta values at 100° C., yet similar warm dynamic storage moduli (G′) at 60° C. The primary tread cap zone and lateral outboard control tread cap element are load bearing in the sense of extending from the running surface of the tread radially inward to the unitary (non-zoned) tread base rubber layer. The zoned rubber tread cap layer and unitary rubber tread base layer are an integral tread composite in a sense of being co-extruded. In one aspect of the invention, the primary tread cap zone rubber composition is silica-rich and the lateral, outboard element rubber composition is carbon black-rich and which furthermore provide a gradation of filler reinforcement content; provide a gradation of silica to carbon black ratio and provide a gradation of cis 1,4-polybutadiene rubber content.

摘要： The invention relates to a tire having a circumferential rubber tread of a cap/base construction composed of a cap rubber layer as the tire running surface and an internal base rubber layer underlying said tread cap layer. The said tread cap layer is composed of a primary tread cap portion and one or two lateral tread cap portions of rubber compositions containing precipitated silica and/or rubber reinforcing carbon black reinforcement and wherein the rubber composition of at least one of said lateral tread cap portions contains a dispersion of short carbon fibers. Said primary tread cap portion contains a major portion of the running surface of the tread and is comprised of a silica-rich or carbon black-rich, preferably silica-rich, reinforcement-containing rubber composition, and said lateral tread portion(s) contains a minor portion of the running surface of the tread and is comprised of a silica-rich or carbon black-rich, preferably carbon black-rich, reinforcement-containing rubber composition. Where said primary tread cap portion is comprised of a silica-rich rubber composition, said lateral tread cap portion(s) is comprised of a carbon black-rich rubber composition and visa versa. The said tread cap portions are load bearing portions in the sense of extending from the running surface of the tread radially inward to said underlying tread base layer. In one aspect, the portioned rubber tread cap layer and the rubber tread base layer are co-extruded together to form a unitary composite thereof.
