摘要： A tire (10, 110) is disclosed including axially spaced apart annular bead cores (12, 112); a carcass ply (14, 114) extending between the bead cores; a belt package (24, 124) arranged radially outwardly of the carcass ply and comprising an overlay coat (25, 125); a tread (20, 120) disposed radially outwardly of the belt package and comprising a tread band (22a, 22b. 122a, 122b) and a tread base (23, 123) adjacent the overlay coat; a sidewall (30, 130) overlying the carcass in a region between the belt package and one of the bead cores; a chafer portion (32, 132) adjacent to a radially inner portion of the sidewall and positioned around a portion of the bead core for contacting a rim; and a shoulder wedge (28, 128) arranged in a shoulder portion of the tire between the sidewall and the belt package, the shoulder wedge being at least partially inserted between the belt package and the carcass ply. The tread (20, 120) includes a tread chimney component (40, 140) extending from the shoulder wedge to the rolling surface, at least part of the tread chimney component extending across the tread band. The overlay coat, the tread band except for the tread chimney component, the tread base and the sidewall are made from non-conductive rubber. A conductive path between the rolling surface and the rim is provided across the tread chimney component (40, 140), the shoulder wedge (28, 128), the carcass ply (14, 114) and the chafer portion (32, 132).

摘要： A method for forming a tire composite tread (100, 110, 120, 130) is disclosed. The method comprises the steps of: selecting a first tread compound having at least one first desired property, and selecting a second, different tread compound having at least one second desired property, forming a composite tread (100, 110, 120, 130) by winding a dual layer strip (210) having a first layer (212) formed of the first tread compound and a second layer (214) formed of the second compound, wherein the composite tread (100, 110, 120, 130) has a first and second zone, wherein each zone is formed by spirally winding the dual layer strip (210), wherein the first zone is formed of said dual layer strip (210) having a strip ratio of the volumetric proportion of the first tread compound to the second tread compound used to form the dual layer strip (210), and wherein the second zone has a different strip ratio of the volumetric proportion of the first tread compound to the second tread compound used to form the dual layer strip (210) than the first zone by varying the volumetric proportion of the first tread compound to the second tread compound. Also, tire having a component, preferably a tread, is disclosed. The component (100, 110, 120, 130) is formed from a continuous spiral winding of a dual layer strip (210) having a first layer (212) formed of a first compound, and a second layer (214) formed of a second, different compound, wherein the cross-sectional shape of the first layer is at least substantially triangular.

摘要： A method and apparatus for producing or characterizing a multi-layered tire tread is disclosed. The method comprises: providing a first rubber composition (24) having a first refractive index; providing a second rubber composition (26) having a second refractive index; determining a difference between the first refractive index and the second refractive index; comparing the difference to a threshold refractive index; adding a refractive index modifier (138, 238, 338) to the first rubber composition (24) and/or to the second rubber composition (26) in case the comparison provides that difference is lower than the threshold refractive index; producing a multi-layered tire tread (10) comprising a first layer (12) comprising the first rubber composition and also comprising a second layer (14) comprising the second rubber composition; irradiating the multi-layered tire tread with a THz electromagnetic radiation; and receiving radiation transmitted and/or radiation reflected by the multi-layered tire tread.
