The 5.4 has plenty of power to push the larger tires, especially if you have performance mods (Intake, Chip, Exhaust) so your gas shouldnt go down a whole lot
The larger tire should even get better gas milage on the highway due to all the E=mx2 blah blah blah stuff unless you go to a huge tire.
basically it comes down to less revolutions so the engine is working less to get you there. Make sure ur speedo is calibrated though or you wont get accurate hand calcs.
My buddy has an FX2 and he put 20"s on his, his city stayed the same but his highway went up to 19.5
He has a flowmaster 40 and Edge evolution tuner.
