Could just be situational. Maybe a headwind, different temperature, speed, road surface? All I'm sure of is that I saw 30 or 31 a couple of times in the four months or so I had the 138s, and haven't seen it since I put on the 124s. I guess I attributed it to the 275mm and 245mm contact patches causing more rolling resistance than the 225mm. Not really sure, though.

Whoa, I wasn't aware of the negative impact of putting larger than stock wheels on cars with automatic transmissions, plus it seems larger wheels are bad for the suspension.

I thought I read somewhere that changing wheel sizes requires the speedometer/odometer to be recallibrated to report proper results...?

I'm not sure why you find these figures hard to believe.
I normally average around 22.5 around town and easily 30 on the highway.

If you're driving at a steady 50-80mph and spending a lot of time in 6th, you'll easily manage 30mpg. I managed 28mpg myself travelling across holland (at an average 65mph). Of course once I hit the border with Germany, and the average popped up to 140mph over the next 7 hours, strangely that mpg figure dropped somewhat

My Ride: E60 530d M-Sport
Guess we wont mention the 44mpg average I got this weekend then hehehehe, pretty reasonable fuel consumption from a petrol tho, but then I used to easily get around 30mpg from my old E34 525i Sport on a run, and thats nearly 18 years old

This was the best MPG I got in my car. I dont remember the exact mpg # but was unbelievable according to the 534 miles I had left till gas goes empty. Also I had f:245 and r:275. I dont think the tires really matter.
like 28-31 range on the highway

I'm getting an avg of 29 all town driving without the A/C on.
Took a long drive over the weekend around 130miles with the A/C on and i was getting 34.4mpg i probably could have gotten better without the A/C on.
