Abstract: A laminar nullprecurednull or nullreplacementnull 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 nullbeadsnull). 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: The present invention relates to a tire having a rubber tread of a lug and groove configuration and of a co-extruded cap/base construction; wherein the tread cap is of a rubber composition which contains carbon black and is thereby of a black color; wherein a visible surface of at least one groove 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 which underlies said tread cap. Said visible non-black colored rubber is exclusive of any appreciable portion of, and preferably exclusive of, the surface of said tread lugs 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.

Abstract: A tire comprising a pair of beads; a carcass ply having ends, each ends anchored to a respective bead; at least one belt ply extending circumferentially around the tire and disposed radially outward of the carcass ply; and a tread portion disposed radially outward of the belt ply. The tread portion has a plurality of tread ribs or blocks and at least one groove disposed between adjacent tread ribs or blocks. In one aspect of the invention, the tread portion is formed from first and second rubber portions. The second rubber portion has a hysteresis value greater than the first rubber portion and a modulus value less than first rubber portion. In another aspect of the present invention, the tread portion is formed from a first and second tread compound. The hysteresis value of the second tread compound is greater than the hysteresis value of the first tread compound and the modulus value of the first tread compound is less than the modulus value of the second tread compound. In another aspect of the present invention, the tread portion is formed from a rubber with a modulus of between approximately 2 and 3 N/mm2, and a tan &dgr; value of between approximately 0.2 and 0.4 under normal operating conditions. The present invention reduces the maximum longitudinal contact stress, maximum lateral contact stress, and the maximum normal contact stress on the tread layer relative to conventional tires, hence increasing the robustness of the tire with respect to tread wear.

Abstract: In a flame-retardant rubber tire comprising an outer rubber body portion consisting essentially of a tread rubber layer, a sidewall rubber layer extending inward from each side edge of the tread rubber layer toward the vicinity of a bead portion in radial direction and a rubber chafer layer arranged in the vicinity of the bead portion, a flame-retardant rubber composition having an oxygen index of not less than 19.8 but not more than 27.5 is disposed so as to amount at least 20% by weight of the tread rubber layer. Such rubber tires are used in electric vehicles, automobiles, airplanes and the like and have excellent self-extinguishing property and flame-delaying property without damaging other rubber properties.

Abstract: A tire is provided with a tread that includes first and second sectors and grooves. The second sectors are formed of a rigid reinforcing compound. Each of the first and second sectors has a contact face intended to contact a road surface when the tire is in use. Each groove includes sidewalls and a bottom, and extends from an end of an adjacent contact face. A depth P of each groove is measured in a radial direction between its bottom and a position corresponding to a radial height of the adjacent contact face. At least one of the second sectors has a contact face that includes a recess having a depth p of less than 2 mm, as measured in a radial direction from a surface of the recess to a position corresponding to a radial height of an adjacent first sector.
