I ran 22's on my car for about 2 years. I just made the move back to 21s. There's nothing wrong with 22s - they look awesome. But if you live around rough roads, you might want to avoid them. I had to get mine re-finished a couple times due to bent lips over that 2 year period, and each time the color came back a little different.
You're also right about the 25 profile....it's very thin. I was able to fit 255/30/22 and 285/30/22 on mine to lower my bending risk, but they just barely fit. If you hit a big enough speed bump you'll rub the rear liner.
On a final note, my local Service Centers
haaaaaaaaaaaated that I put 22's on my S. They basically refused to touch it unless I put my factory wheels back on before I brought it in.
I had the pleasure of seeing SnakeDoctor's car - it looks stellar. He's running 20" wheels, so that gives him a bit more wiggle room to eliminate rubbing in the front, and you can certainly fit an 11" tire in the back if you have enough offset and you stretch the tires a bit, like he mentioned.
