The standard square setup is rear wheels/tires all around, not fronts. The rear 8.5x17 wheel and 255/40/17 tire will fit in the front just fine.

But you'll also need to upgrade the suspension (adjustable sway bars and maybe coil overs) because the car will go from the stock understeer to lots of oversteer in the square configuration. The suspension adjustments can bring it back to neutral or whatever you like.
