IMO, if the sign is a generic one like this
https://en.wikipedia.org/wiki/Snow_tire#/media/File:CZ-C15a_Zimn%C3%AD_v%C3%BDbava.png
then map generically "winter equipment", but if it is more specific, like
this
https://www.sicurauto.it/upload/news_/8684/img/2038-cartelli-sperimentali-pneumatici-invernali.png
then definitely we should map what it says, i.e., either M+S tyres or snow
chains mandatory between day X and day Y.

In Italy, for example, the latter kind is way more common, and is very
specific and doesn't require any knowledge of the local law - which (off
topic) should be a requirement of any road sign anywhere: how am I supposed
to know what the hell the first sign means exactly?

Would you care to expand on this? What we commonly call "winter tyres" are
actually M+S (mud and snow) models.
