You probably also lose some range/efficiency driving on the all terrains. However, I haven't seen that tested. I doubt it's a big impact though. Based on Town & Country's leveling and bigger AT tires, they only lost about 5% IIRC.I am getting this type of usage as well with my daily drive to work and home. Typically average 2.7 or better round trip which is almost 350 miles on 128 kw useable battery. Since I took delivery, I’ve driven over 900 miles and my average is 2.3 mi/kWh, and that’s with several ”joy riding” sessions where I’m showing friends how fast the truck is as well as with climate control mostly wide open and the average temp for the last 2 weeks has been in the upper 80’s. That average is not any interstate driving, just a couple 10 mile trips on the parkway here. I would say over the last 400 miles I’ve averaged closer to 2.5 mi/kWh. I really don’t think it would be hard to get 2.5 mi/kWh or better with normal highway/city driving in this truck, but I think interstate at 70 mph or faster you are looking at between 2.0-2.3 mi/kwh average. I also have the Lariat/ER with All terrain tires and I added a bed cover which I think has help slightly but likely not more than 7-10 miles on a full charge.
