Fursty; I have a set of genuine Volvo winter wheels with Conti Winter Contacts as per this link. I used them sparingly during 2 winters and they have between 6/7mm mm tread across them. Wheels are unmarked. I've swopped my MY18 V90 for a MY20 V90 CC and unfortunately they're not Volvo recommended to fit it. I have the original bill from Volvo Rybrook.
