fyi: the Michelin PSS does not come in a 255/40/17, only 245/40/17. And the 245/40/17 PSS is a slightly narrow
245. I've seen it on 17x9 and it looks too small (sidewalls where not square, they were rounded). According to TireRack, the tread width is 8.5" vs the Dunlop Z2 9.2" I'm not saying its a tiny-ass tire, but it certainly doesn't run wide (PSS in other sizes might).
