I routinely skip a gear or 2 around town, ie 1,2,3,5 or 1,2,4,6. Really don't watch the tack that much, but I do get into 5 or 6 by 40-45 mph at a leisurely pace unless bumper to bumper. BTW, for around town I mean city streets, not 55 or higher urban highways. Tires are 1.3" or so larger diameter than stock, and about 30 revolutions difference per mile (computer is being fed less revolutions by sensor). Definitely meaure odometer error, I ran it thru a calculator, and came up with 3.3%, which would be about a .5 mpg (calculation based on diameter of brand new stock/larger tires). As tires wear, your gas mileage seems to improve as tires gradually become shorter.
Also, spend $8 at walmart and get a Slime digital pressure gauge. Only other choice I see is less aggressive tires.
