^^ What he said.
I would not run staggered tire sizes on those wheel. I prefer a square setup as I find that it maintains the car's neutral balance. I found that staggered tires induce understeer.
I ran 235/40R17 all around on my 17x9 +20 with just rolled fenders and -3* camber all around. I did fit 245/40 in the rear on those same wheels too. That size would have probably fit on the front as well. With your +22 offset you could definitely run 245/40R17 all around.
