With full-year tyres in winter to southern Bavaria?

Hello, will spend the next few months in the greater Munich area as well as in the Alps (near) and are looking for winter-friendly tyres. As a city driver from NDS I am quite unbiased for an area like southern Bavaria. If you don’t get into extreme weather now it is possible to travel areas like Garmisch-Partenkirchen? I’m not an enthusiast and ride “only” a Polo 4 with 75 HP on the Zugspitze so I won’t be able to ride it anyway The Polo still had Goodyear Vector 4 Seasons Gen 2 195 50 R15 which are now pretty low and now have to be replaced.
