I asked the same question some time ago on this forum and I was told by several people that the factory supplied Pirellis won't fit on a 17x9 rim, it's just a little too wide for them. Hope this helps.
Because I can get a set of black bullits for $112.00 per wheel and free shipping, not to mention the fact that the tires are like new...so what's the answer to my question?

looks like the rims are too wide - maximum rim width for the stock tires is 8.5". The best places to get this information are the tire manufacturers websites. I would never run a tire and rim combo that was not approved. See attached link to Pirelli Pzero Nero specs
