    Just curious what is your average speed to get 14 is it daily driver? Mainly highway ? I have been sitting at around 12 with 275s. I’d love to know what your doing to get 14.

    Going from 32 to 34”, I am 6% faster than what my speedo says and my odo is calculating 6% less. So my mpg math needs to take that into account if using odo/trip readings, correct?

    Tire Weight can be a major factor, but not this much.

    Tire pressure, alignment, and check over all the lift components.

    Hell, I would get better mileage towing this:
