Depends on how you define "fit". The wider tire will (most likely) fit the stock 16" rims.

However, the sidewall on the 245 tires are 7.23" tall. The sidewall on the 215's are 5" tall. The taller tire will have a larger circumference, meaning your speedometer and odometer will actually be reading low.

Also, there's a good possibility the front tires will rub the suspension or the inside of the fenders when turning.

Yes or no

Usually the factory puts the biggest rubber on a car that the wheel can safely handle, so nope, you'll need a wider wheel…

No, not even close. A 245/75-16 sized tire is both too wide and too tall for your Taurus.
