embarrassingly bad mileage... REALLY

[ChinoCharles]

It definitely sounds like a problem with the car. I don't know what I'd have to do to get under 30 MPG and I drive 90% city and ignore the RPM mileage rule. I would keep track of mileage on a couple of tanks and take that info to the dealership and see what they say.

I'm averaging about 23-25mpg with the use of my starter, idling waiting for people, the extreme cold, and driving around in city traffic and heavy-working roads (snow/salt/slush/sand). Your tires (and I'm assuming after-market wheels) likely doubled what you had stock. So it doesn't really count as an "only" type of mod, as it's one the worst for killing gas mileage.
