Hauling 88-90klbs one way on fairly short runs and flat ground with 3.55 ratio on 11R24.5 I will get 5.2-6.0

If the weather and wind cooperate and I try my very best (65mph) I can get into the low 6's during the warmer months. I do not run the most fuel efficient tire, if the wind is bad it plummets, now with winter and cold ambients and winter blended fuel it will be in the low to mid 5's.
