Tire size vs. Gas Mileage SURVEY! participate! 700

Hey. Just been thinking about my mileage (again).

I noticed in some posts about mileage that people, regardless of everything else, seemed to have better mileage in their bricks with narrower tires compared to my 205/55/16's on Hydras. I am running a car with the estimated lowest mileage - B230F turbo, AT, 4.3(highest) differential. I don't really need the extra big tires, so long as I don't drive like a moron, so I'm considering buying 4 rims from pickNPull getting a super cheap set of tires, and seeing how it works for this summer. I'm going to be living out at my parents house - which adds an extra 18 miles to every trip to the store, the movies, work, etc. and it might be a good proving ground.

So, before I go spending money (and meticulously recording my results for you all ;) ) if you're intrigued, maybe we can post tire size, AT, diff size, turbo or NA, and city/hwy mileages. Might as well see if we can all save some dough for a little less traction.
Thus, I will go first.

90 740 turbo - 205/55//16. 17/23

On another note, I'm planning on a new radiator (crappy, leaky 2-row aftermarket rad), E-fan conversion, and toying with the idea of a differential replacement to the mid-grade (3.8?) differential.

Thanks everyone!
-Will
