Agreed. Rolling resistance plays a big factor in MPG and his would be much lower than that of a truck with larger looking tires.
Actually, it would appear that he was going farther than he actually was going, the mpg reading would be higher with smaller tires since each revolution would be less distance than the truck thinks it is.
Im driving at a Much Higher RPM now. The milage sucks ofcourse. The only thing thats fun is 0-60, Chirps 2nd crazy lol. Im using the GPS for MPH until I put the tires on Im sure I want after the drop kits installed.
