Will stock rear 245/40R17 wheels fit on the front?


My questions:
- Will the stock 245/40R17 fit on the front?
- Will it ever rub?
- Will it "improve" handling and not hurt ride, etc? Any downside? Will it make the highway driving more "squirrelly?"
Under hard cornering, I think I found that the car had some understeer, so the wider tires should put more oversteer into the front. What do you guys think?
