    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: A heavy load pneumatic tire (100) includes a carcass ply (40) that forms a framework of the tire, and a belt layer (15) located outside the carcass ply in a tire radial direction in a tread section (10). The carcass ply (40) includes a first curvature change portion (P1) that is a boundary between a first segment (P0-P1) containing a tire equator line (CL) and a second segment (P1-P2) that is located outside the first segment in a tire width direction and inside the first segment in the tire radial direction and whose curvature is larger than a curvature of the first segment in a cross-section, and a second curvature change portion (P2) that is a boundary between the second segment and a third segment (P2-P3) that is located inside the second segment in the tire radial direction and whose curvature is smaller than the curvature of the second segment on the cross section. The tire further includes a cushion rubber (17a) whose inner edge is located at the first curvature change portion (P1) and that is disposed between the carcass ply (40) and the belt layer (15).
