but, that aside, i would just PM someone on here who's done it without issues.
you're gonna get your ***** busted for even asking that. just so you know.
www.nittotire.com - view sizes and specs for their rim width recommendations.
I just put some 305 tires on a 10" wide rim. The 12.3" wide tire ended up at 11.7" after mounting on the 'slightly' out-of-spec recommended rim width (10.5" was minimum, 11" was optimal).

Aside from the wheel lip itself, my 315 Nittos look and fit my 9.5" TT2's nearly identical as the 315 Sumitomos fit my 11" TT2's. I wouldn't even consider doing this with any other brand tire, but the Nittos are obviously exaggerated as to their true size listed on Nitto website. Mine measure 10.5" wide at the tread, roughly 11.5" at the largest part of the bulge. I'm going to say that judging by the above pics, yours show that they are the same 10.5" if measured at the true and actual tread width...the part that touches the ground at normal air pressure (and has dust on it), not the part that's rolled around to the sidewall.

I talked to a tire shop about this today and they are pretty reputable and they told me that they would mount 315 nitto's on my 9.5 ZO6 wheels but told me the same thing that there would be a buldge in the middle and cause some wear issues, anyone had that problem?

Here's shots from the rear, showing what I mean, compared to how they fit an 11" wide wheel:
