No, but rally cars do, Celicas used 18" wheels on tarmac events. If you like 18s then stick em on and enjoy them. I have run 18s for years now without issues and thats on crappy UK roads.
The only issues I have with 18s is the price of the tyres, 17s are so mush cheaper which at the end of the day might be the deciding factor. 16s are too small, you`ll end up with side wall roll when pushing hard through corners.
Put them on and see how they go...if you like them then keep them, if not try and swap them for some 17s or sell them and buy something different.
