[s-cars] Loss of mileage, continued

[TM]

For those of you who have been helping me with some useful comments,
I appreciate it. I'm still in the process of trying to figure out what
is causing my mileage loss.

One thing I forgot to mention that may be relevant- how much mileage
loss
have you experienced when going to larger tires?

I'm running HTR-ZII 255/40R17, obviously the increase in rolling
resistance
will take a toll on mileage, but going from 225/45R17 to 255/40, I
wonder
how much of a difference this will make?

Any BTDT on that?

Also, on average, what is your mileage loss when running the A/C all the
time?
