Feel for you. I cannot understand the ridiculous move to low profile tyres on none sports cars. I’ve had two punctures on my 19” wheels in the last six or so months so part of it is just the general state of the roads.

Have you tried asking Volvo what winter tyre & wheel sets they sell for your car? I only ask because if one of those options is 20” wheels then you have the answer you want. The alternative is to do the same on Volvo and aftermarket resellers websites in North America and Germany where winters can be harsher and people tend to shift over wheels and tyres.

I run full winter tyres up here in rural Scotland and am not suggesting you do this if you don’t wish to rather it is an interesting way of finding out if 20” wheels are actually approved.
