mileage calculation?

[Deezel4x4]

is there a calculation to determine mileage when the tire size has been changed?I have a 12v auto with 3. 54 gears and have recently changed the tire size to 305/70/16 on stock steel wheels.

I feel like my mileage is down but I don't know how to factor in the change in tire size when determining fuel mileage?

help

Plug in your numbers and hit calculate. Your total miles traveled will be off about 7% And the speedomter indication will be off 4. 75 mph to the low side.
