    I'm currently in a 4.6 and have no idea what my average mpgs are with the 285/70/18s and a Toytec 3 inch lift. For any of you with a 5.7, 3 inch lift, and 285 or 295s, what is your average mpgs? I'm considering a 2020 and will move my lift setup over to the new one if I buy it. Thanks.

    275s and no lift drop it down about 1 to 1.5 MPG to an average of 13-14 ish, little better if only highway. So 285/295 will put you at about 11-12, less if you are heavy on the throttle. And you need to add the % difference in tire size to your MPG calculations, otherwise it will appear even worse.
