Are winter tires available for the FS?

Options for the front wheel:
- Schwalbe Marathon 365 (55-406): offers more grip in wet and cold conditions than the standard Schwalbe Big Ben.
- Schwalbe Winter Plus (55-406): studded with spikes for compacted snow or icy roads.
Options for the rear wheel:
Currently, the only alternative is the Schwalbe Pick-Up (60-584), which has more tread than the standard Schwalbe Super Moto-X (70-584), but it is not a dedicated winter tire.
Please note: While other tires may fit the rim and frame, they often lack the required load capacity and are therefore not approved for use on the Ca Go FS.
