I jumped up to 255 on the fronts & I love it (still running 265 rears). If your front wheels aren't wide enough (pre '12) for a 255, I'd recommend at least going to 245. YMMV....

Thanks for comment Mike. But no rubbing on stock suspension?
Yes, I have pre-'12 wheels (19x8 and 19x9) and I would happily jump on 245/275 setup, but 245 on 19x8 seems somehow too much. Maybe for normal driving it's fine, but wouldn't it be too wide for these wheels for occasional track? PSS is a bit wider than other tires too.
Did anybody track their IS-F with 245/275 PSS set on '08 wheels? No problem with front tire being too 'floaty' (because of narrow rim)?

Hence the whole reason I bought the later model OEM wheels. That extra half inch in width opens a whole lot of doors for sizing. I am running 255/275 PSS. There are a couple of folks who have done this on the earlier model wheels and have stated they work just fine. I'm not a big fan of going wider than the tire manufacturer recommends, but it can work. I ran 245/275 on the earlier model wheels and it worked reasonably well.
235/265 is going to do some really odd things in terms of suspension geometry - scrub radius in the front will be significantly different, so I don't know if I'd be excited about that. If this isn't a big deal, you're primarily concerned with appearance and don't push the car's mechanical performance limits, you'll likely be fine.

Thanks for the input!

The tire diameter is significantly different on the 235. To maintain the suspension geometry, you want to fit tires with diameters as close as possible to the OEM diameters. Scrub radius is one of the numbers I really don't like to deviate from if I can avoid it. It can cause all kinds of weird handling issues. 255 is actually pretty close to ideal in the front.

Yes. Essentially put the OEM rears on the front and fit the 275/30 in the rear. I'd prefer 285 or 295, but they're not a great choice with a 9 1/2" rim in the back.

I guess I'm a little hesitant on the 245 & 275's on the 2011 wheels because I'm not sure the wheels are really wide enough for those tires.
