This was discussed on Car Talk a couple of weeks ago. The fellas debated for a while (as they do) but decided that since the tanks at the stations are underground, and the earth maintains an almost constant temperature at that depth, then the volume of gas wouldn't vary to a measurable degree throughout the day.

did you regear for those bigger tires? if not i bet you would get better mileage if/when you do.
Bottom line is the slower an engine turns at a given speed, the better - that's why almost every vehicle has an overdrive transmission. Also, bigger tires mean lower RPM, so it's almost like overdriving.
The pitfall is if the engine does not make enough power at that RPM to comfortably push the vehicle at the current speed - which leads to constantly kicking down the transmission, etc. which is hard on everything and kills gas mileage.
Didn't mean to call you out, but everyone says it as if it's a total given.
