摘要： The invention relates to a method for manufacturing a studded pneumatic tire for a vehicle, the tire comprising studs (10), at least one ply (288), at least one metal belt (286, 287), a cap layer (23) forming at least part of a running surface of the studded pneumatic tire, an underlayer (21) made of a first rubber compound, and an intermediate layer (22) made of a second rubber compound, the intermediate layer (22) being arranged, at least partially, between the underlayer (21) and the cap layer (23), wherein the method comprises steps of forming an annular belt comprising a metal belt, the underlayer, the intermediate layer, and the cap layer, then arranging the annular belt onto an annular carcass comprising the at least one ply to form a preform, vulcanizing the preform, and installing studs. The invention further relates to a studded pneumatic tire for a vehicle.

摘要： The invention relates to a studded tyre for a vehicle, comprising a tread (18) provided with a number of anti-skid studs (10). The studded tyre comprises an underlayer (20) arranged below the tread and comprising an adaptive material layer (21). The anti-skid stud (10) is arranged at least partly on said underlayer (20), and the shape of the stud, in combination with the underlayer, is arranged to provide the anti-skid stud with a stud force, wherein at an ambient temperature of 0°C, the stud force of the anti-skid stud is at least 6% greater than the stud force of the anti-skid stud at an ambient temperature of 20°C, and at an ambient temperature of -30°C, the stud force of the anti-skid stud is at least 20% greater than the stud force of the anti-skid stud at an ambient temperature of 20°C. The invention also relates to the use of an elastomer material.

摘要： A pneumatic tyre for a motor vehicle. The pneumatic tyre comprises a first side that is an inner side of the pneumatic tyre, and an opposite second side. A least a part of the pneumatic tyre comprises rubber-based material that is configured to restrict gas permeability and that comprises lignin that has been treated by hydrothermal carbonization. The rubber-based material or a coating of the rubber-based material forms at least a part of the first side of the pneumatic tyre. A method for manufacturing a pneumatic tire.

摘要： A tyre (200) comprising a tread (210), multiple studs (100) in the tread (210), - a metal belt (286) extending circumferentially around a rotational axis of the tyre, and a textile belt (284) comprising a strand (310) running around the metal belt (286) multiple rounds (311, 312, 313, 314). The textile belt (284) is arranged between the tread (210) and the metal belt (286). At least pins (110) of the studs (100) are exposed on the tread (210). A first round (311) of the strand (310) is spaced apart from a second round (312) of the strand (310) such that a first spacing (SW1) is arranged between the first round (311) of the strand (310) and the second round (312) of the strand (310) in an axial direction of the tyre (210), the first spacing (SW1) having a width of 5 % to 50 % of a width (W2) of the strand (310).

摘要： A tyre (200) comprising a tread (210) and multiple studs (100) in the tread (210) such that at least pins (110) of the studs (100) are exposed on the tread (210). The tyre (200) is configured such that a load index (LI) of the tyre (200) as defined in The European Tyre and Rim Technical Organization Standards Manual (2023) table G.7 is from eighty-six to hundred sixteen (from 86 to 116). The tyre (200) is further configured such that a road wear of the tyre (200) as measured according to the standard SFS7503:2022:en is less than the value calculatable by the polynomial formula -0.000139×LI 2 +0.0431×LI-1.90.

摘要： An article that is not pneumatic tyre for a motor vehicle and that is suitable for use as at least a part of a pressurizable container or pipeline. The article comprises a first side that is, in use, configured to be exposed to a first environment and a second side that is, in use, configured to be exposed to a second environment. At least a part of the article comprises rubber-based material that is configured to restrict fluid permeability and that comprises lignin that has been treated by hydrothermal carbonization. The rubber-based material or a coating of the rubber-based material forms at least a part of the first side, and the first side is, in use, configured to be exposed to a higher pressure than the second side. A use of the article. A method for manufacturing the article.
