Hello guys I’m still at the final configuration for a V90 Cross Country. It’s about the following: The vehicle must be as quiet and as comfortable as possible! The acoustic glazing is therefore a must. Actually I like the 21 inch rims. Now I was told that these are significantly harder due to the lower cross section and also have a somewhat louder rolling noise. So I would have to return e.g. to the 19 inches. In the chassis the “standard” is minimally tighter than the 4-C in Comfort mode. However, there is less resonance noise than the 4-C. Therefore a question about the 4-C. If I take the 21 inches, the 4-C balances that again or better the standard chassis and the 19 inches? Who can help me there? Thanks in advance and greetings from the CH Stephan
