The details: on my first full tank after having the larger wheels and tires, I observed 13.5 MPG. This includes the +10.43% adjustment to the odometer's reading because of the increased overall diameter. During this same period, I had a remote starter installed and would let my car run, on average, for ~5 minutes prior to launch. Furthermore, there was no significant highway driving during this tank - in fact, I would qualify my driving patterns during this time as a "worst case scenario." Additionally, I have a CEL because of O2 sensors, which I understand may impact fuel management. And finally, this is winter gas, which may be less efficient than the summer blend.
I'm going to try and get some highway miles on this tank to achieve a fairer comparison to my average tank. I've not been in Power mode, either. I may wait for the tank after this one, in order to observe one variable at a time.

Updating with info from tonight's full-tank refill:
15.5 MPG
70% highway driving
Power Mode OFF
CEL still on
Power Mode is now ON for this tank, but I'm not sure I'll be able to replicate the city/highway split.
