The circumference of a 245/40/17 will be very close to the OEM size and also very similar to a 225/45/17.
Plugging in the various sizes here is very helpful.

I'm interested in the clearance too. I think for my opening season in this car with 200TW tires I'm going with 225/45/17, but 245/40/17 is tempting for use in the future.
