Which rim size at nem Coupe

Hello, I had 17s on my coupe, looked great, but could have been one inch bigger, but this is almost impossible with the LK. But since the 17s are not there anymore, and my Audi Gulli lids might let out some air, I need new ones. Since the money is not so loose, and in an anti-conurbation center is not much choice, I want to ask the people of the bay. Then I realized that there are less 17s, and many 16s. Besides, the 16s are a good one. I think that they look a little bit small, where the most beautiful rims don’t help anymore. Does someone have 16s on their coupe (if necessary also Limo) and can post a picture? Or has already seen several of them and can tell me how they look like. Oh yes I have on my old rims R15/185/65 winter tyres if I’m not mistaken, how wide can the new rim be than max. so that you can still use them? Would she like to leave in winter.
