The answer to my question, then, is "Pre Raven technology".
No, I haven't seen the tires on the CT. I've never seen any part of one. Now tires can have a significant effect on stiction and there are tires made specially to reduce it. Also increasing the diameter of a wheel/tire (or in particular the distribution of mass with radius) influences the rotational moment of inertia. There is energy stored in a rotating wheel and just as you cannot recover all the translation kinetic energy you cannot recover all the rotational and a larger diameter wheel will cost you some in range.
In any event I think it is fairly obvious that Tesla isn't going to want to go over 200 kWh with the battery and that, therefore, the stock CT will be about 350 Wh/mi. There will doutless be, as there have been with other Tesla offerings in the past, other wheel options which will cost $ and range.
