I have a 98 A6 Q 2.8 with 18" rims. I really like the rims but tires are not so good.

What size of winter tires can I get on these things? currently I have 205 45/18 on them.

Thanks

Cheaper and better to buy some 16's or even 15's.

Generally speaking, you should go smaller and narrower for winter tires. 18s are not so good.

...and agree with the others; generally narrower is better. However, in my case, I wasn't willing to give up all of the reasons I bought an A6 in the first place: Speed, Handling, and Braking. With quattro, I felt much more confident in the A6's ability to get traction with a little wider tire. So, instead of a narrower Snow and Ice tire (like Blizzaks - which I've used on other cars in the past), I opted for a set of Dunlop SP Winter Sport 3D's in the stock size (235/40VR-18). We had an above average amount of snow last year (I live about 30 miles from the crest of the Cascades in Washington State) and I was more than satisfied with the perfomance of the tires. Plus, I lost nothing in the handling department when we had dry pavement in-between storms. Highly recommended, YMMV.
