Abstract: A laminar “precured” or “replacement” tread for wheeled vehicles operating at night on retreaded tires is made more readily visible when grooves in the tires are provided with elastomeric strips or bands in which are embedded retroreflective elements such as transparent glass or synthetic resinous microspheres (referred to herein as “beads”). Upper surfaces of longitudinal ridges in a flat curing mold lend themselves to supporting the strips which are then precisely positioned in grooves defined by the ridges, when the flat tread is cured.

Abstract: A pneumatic tire comprising a black colored tread with at least one colored groove wherein the top surface of the tread designed to be ground-contacting is essentially free of non-black color. A non-black component is placed over the tread strip and covered with a thermoformable film prior to forming the groove pattern. After vulcanization, the film is removed, and the tread lugs buffed free of color, if necessary, thereby forming a tire having color localized in the tread grooves.

Abstract: A crack suppressing rubber, which has elongation-at-break which is superior to elongation-at-break of a cap rubber, is disposed so as to reinforce a vicinity of a groove bottom of a circumferential direction narrow groove provided in the vicinity of a shoulder of a tire tread. Due to this, generation of cracks from the vicinity of the groove bottom, at a time when land portions at an outer side of the circumferential direction narrow groove are greatly deformed due to a large lateral force or due to recesses and projections of a road surface or the like, and growth of generated cracks are suppressed. As a result, breaking of land portions at outermost sides in a widthwise direction of a tire, and separation of the tread can be effectively suppressed. Namely, in accordance with the present invention, there is provided a tire which is suited to heavy-load vehicles and in which generation of cracks from groove bottoms of tread grooves (circumferential direction grooves in vicinities of shoulder portions, in particular) and growth of generated cracks can be suppressed.

Abstract: The present invention relates to a tire with a carbon black-containing, black-colored, circumferential tread of a cap/base construction, wherein said tread cap has a lug and groove configuration and wherein the outer surface of a major portion of said grooves are designed to be ground contacting, and a co-extruded thin outer non-carbon black-containing rubber layer of a non-black color wherein said outer rubber layer is integral with and circumferentially extends from the axial outer edge of said tread cap to include at least of a visible surface of at least one groove in said tread cap. In one aspect, said tread contains a pair of black colored, carbon black reinforced, tread miniwings which extend from the axial outer edge of the tread over a portion of the tire sidewall, wherein said thin outer rubber layer joins said miniwing and wherein said tread cap, tread base, tread miniwings and thin outer layer are co-extruded, co-cured and therefore integral with each other.
