Winter tyres for V60 (2019)

Hello, I bought a Volvo V60 BJ 2019 about a month ago and am now looking for suitable winter tyres. Currently I have Pirelli summer tyres in the dimension 235/45 R18 98W on it. If I look around now in the various online shops for winter tyres in this dimension I find with some at all no tyres or very few to me unknown brands. From the information in my registration certificate I do not get quite clever. Here are so many different, partly in komis The current summer tyres have the speed index W = (270km/h maximum speed). The maximum speed of the V60 indicated in the registration certificate is 220km/h. Would it therefore not be possible or permissible to install tyres which have the speed index V = 240km/h maximum speed? I would not have a P roblem more to find a suitable winter tire. I come by the way from Austria, this should be important for this case to know. LG firebb
