  • Publication number: 20240375457
    Abstract: A tyre (200) includes 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 one 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×LI2+0.0431×LI?1.90.
