So you can see what it looks like mounted on, here are a few pics of my stock 17x8 rims with Nitto DRs in 270/40/17 size in the rear with the stock goodyear in 245/45s on the front. Nittos supposedly run a little narrow compared to the rest and IMO, are acceptable for the rears only. Fronts on a 17x8, I personally wouldn't go wider than 255/45/17s.
