225 is a tad wide, a 185/60 will not be stretched you would need to do something crazy, like 155/55 165/55 which would be motorcycle status. I ran 185/60s on my Ptypes and had no problem with it, 195/60 is nice as well.
As for the 225 in the rear it would most likely rub, my mate had a 225 tyre on his 15x7.5 Equips and we would cheese grate the tyres when we had a third passenger!!!
185, 195, and 205 would be safe to run I've ran all of those 205 is a bit pushing it but it will work.
Hope this helps!
Cheers
