The Fahrzeugbrief (the German equivalent of a US title) spells out not only things like tire size but in some cases even approved manufacturers. Any deviation (aftermarket wheels for example) must be tested for that application and an entry made in the document if approved. Some manufacturers will get pre-approvals for certain applications so that no separate entry needs to be made - but the manufacturer's approval document needs to be kept with the car.

It is quite possible that a 16" wheel might require a supplemental authorization if the 328 doesn't come with 16" wheels fitted as standard in Germany. However, the 328 comes fitted with 205/55 R 16 H tires, so your Opel mechanic was wrong.

Long story short - you're perfectly fine on the 16's. The smaller tires will give you superior winter performance and would be the appropriate size for that car in Germany and in the US.
Ceb - you got me, I am driving an American spec car. Thanks for clearing up what he was talking about. He did mention the Fahrzeugbrief and I said I didn't have one since it was US spec. It still concerned me though since I had never heard of an issue like that before. Later on I went through the manual ( LOL) and saw the 16" mentioned, with the only difference being an H rating noted in the manual vs. the V on the Michelin Pilot Alpin PA3 XL that I bought.

Thanks again for clearing up the Fahrzeugbrief issue and thanks to the other posters for their responses.
