Mick,

Lacota covered it pretty good.

Tire's do have a Rolling resistance that does make some difference:

I'm averageing 20.6 mpg with my '13 AT 2wd svv6 Frontier, and that's mostly in mixed driveing.

Like Lakota said, the Brake's eat up the Fuel Mileage, so the less that they are used the better for Fuel Mileage.   Learning to judge the red light's and reduceing the speed, ahead of time, and avoiding a full stop help's mpg, cause it take's more fuel to get going again from a full stop.  That also help's to prolong the Brake pad's, which is a Win Win.

Takeing off slowly, rather than giveing the engine a lot of gas, also help's a lot in MpG.

One other thing that really help's me, is that I make a list of what I need, and try to get everything that I need when I make a trip into Town.  I'm retired, so that help's me a lot, but I started doing that when I was employed as well.

I think Lakota covered everything else, and like he said, monitor the Tire pressure and keep the pressure at least what's recommended by the Owner's Manual.

I've alway's kept a little pocket notebook in my Truck's and check the Fuel Mileage @ every Fill up.   That let's me know, what the mpg's are,, but also if the mpg's start falling off, to alert me to double check thing's to make sure that the Engine or something else in the DriveLine might need some attention.

Hope I didn't ramble on too much, but I get a kick out of trying to get the best MPG's that I can out of my Current and Past Vehicle's.

HTH & Good Luck
