Wider Tires on S4 Wheels: Ideas?
Discussion
I'd like to go to 225 and 255 series tires on my S4 (up from 215/245) as these are marginally wider then stock and, more importantly, the widest tires that will fit on the stock rims which are 7 and 8.5 inches respectively.
The rear tires are no worry as 255/45s are widely available and do not alter the overall diameter of the wheel/tire very much at all.
The fronts are the issue. Nobody makes a 225/40, which would be perfect, or a 225/35 which would be OK too. All that exist are 225/45s but these seem to be too tall.
Here’s the calculator I’ve been using:

What are others doing?

I was contemplating this same issue just recently. You could always go with wider wheels and I was || close to getting new wheels. The Last OZ Esprit wheels being my favorite or the Ronal Eleganz my second favorite. But alas, the small fortune required made me steer clear... for now. I figure I'll just up the size a touch, like you are thinking about now.
For the fronts, if you choose 225/45, you gain just .4 inches in overall diameter. I don't see how that could rub. I am not up on what size wheel fits what, but can a 235/40 fit? Pleanty o those available. I know a friend had those on his DSM and I could have swore his rims, Konig Villians, were 7" X 17" rims. I know on my DSM, 6" rims were stock and I fit 225s on them, as did many other people I know. Worse comes to worse, leave the fronts stock size.
For the rears, Would a 265/40 fit the 8.5" rim? Plenty of tires for that as well. Something else to think about if they fit.

Generally...
235s require at least a 7.5" rim and 265s require a 9 inch rim. I'm working with 7s and 8.5s
If you do the 225/45s on the front and the 255/45s on the rear you're changing the diameter of the front much more than the rear. Not sure if this is significant of an issue though...

A once had a tyre retailer's catalogue which gave things like contact widths and rolling radii for all sorts of manufacturer's tyres (for each specific size), and the figures were startlingly different.
The catalogue, even if I still had it, would be years out of date now, but what I am getting at is for the tiny increase you would get by changing section, a different brand may yield the same results.
