225/40/18 has a diameter 25.1" and 245/35/18 is 24.8". You're better off going with 215/40/18 so that the diameters match front and rear at 24.8".

Here's a link to a Tire Size Calculator which will help avoid drastically different sizes which can upset the anti-lock brakes, stability assist, and the speedometer. You still need to fit them in the wheel wells. :)

Stock CR tire sizing differs even more...
