I have much worse milage with the 17" rims in summer or with stock rims when it's cold. If you care:
Auto tranny, 04 model, stock tires, summer time = 30mpg city (driving like grandma), 28mpg if I drive like I'm awake.
With 17" Sendel S15 chrome rims and Falken Ziex 512 205/40/R17 = 26 MPG.
Winter time, stock steelies with Blizzaks = 24 mpg city.
Radically altering your xB's look for almost no effort = priceless.

I'm lowered 2 inches already..gives me a pretty low center of gravity for the turns.
with the 18's the pot holes are almost unbearable...and I have already had to buy a new rim with almost a 2 week wait for the right one..all I can say is about how much money it cost...is ouch!!!
I can drive smoothly over things I would have had to slam on the braks and crawl over before...
if I wanna drive fast I own a fast car for that..I didnt buy the Xb because it is fast

I switched to a lighter 15 inch wheel. Saves me about 6 pounds all the way around over stock.
I didnt realize it at first, but my mpg seems to have increased by about 1mpg, sometimes 2.
Was getting about 33-34mpg with steelies, but now average 34-36 for the most part. Havent had under 34mpg in probably 8/10 fill-ups.

Another issue:
The closer your tread width demension is to the actual rim width, the better the handling performance of the tire. If rim width much narrower, more supple ride quality, less handling.
