Hello, I have on my V90 CC the Michelin Pilot Alpin 19 inch winter tires. The car is brand new. However, from about speed 60-90 up to high speeds a clear (!) rolling noise is to be heard. It is much louder than in my previous XC60 with 18 inch tires or the Passat Alltrack before. In short: is it really because of the tires, which actually have similar noise values according to test like many others? Are it the big wheel boxes? Is the difference from 18 to 19 inch so great? Do you (V90 CC) have similar experiences? It sounds like armored tires and resonances with a surren that gets brighter at higher speeds. Thank you! Many greetings, berg4m
