tyre sizes for a 19" rim

[billy g]

Hello, could anyone offer any advice on tyre sizes for my standard a4 b8 2009 2.0 tdi. i love my audi in meteor gray but needs a set of cool wheels to finish it off. I have the 245 45 17" set up just now. i have seen a set of speedline 19" wheels for sale but the tyres on them are 255 40 19, and usually the correct tyre size i think audi recommend is 255 35 19, is that right? would the 40 profile be ok, no rubbing etc or is it to much, maybe throwing out the speedo, handling, abs or anything else, sorry the wheel size is 19" x 8.5" which i believe to be the correct width for standard a4 b8. any help on this would be great thanks billy g.
