The larger tires give you about an extra 3.3% mileage above what the SID reports. (Assuming you didn't re-program the tire size with Tech-II.)
So are you comparing before & after the tire change? Or these #s are with the larger tires?
I don't really trust the SID for absolute mileage - it's always a few percent optimistic vs. actual gas fill records. But it's a good indication of changes when you compare before & after you make some change.
