15" is standard here in Denmark even in the higest trim edition..
The dealer could fit 17" on it. But from factory it is 15"
Are the noise worse or better with 17"

based on driving 17" and 15" back-to-back when I was looking to buy, I'd say the 17's are considerably noisier than the 15's, but it was about 11 months ago and I didn't really do the full gamut of speeds and I had already decided on the 15" wheels because of the superior ride quality and suspension optimisation.

Certainly I don't find the car to be excessively noisy, although there is inevitably some road noise because other aspects are so quiet... Up to about 40 mph I'd say it's one of the quieter driving experiences, above about 70 it does become more obtrusive.

Although opening the window at that speed does give a sense of relativity.
