Help with math?

if i understand correctly, a larger diameter tire lowers your ratio. In other words, if I have 3.73 gears, a taller tire could lower it to 3.5. the lower ratio would mean that at the same speed, the engine is at a lower rpm, correct? If this is the case, why does everyone say they notice a drop in mpg with larger tires?
