I have a long range model 3 with the 19 inch wheels, temperature plays a factor but I’ve noticed nothing plays as big of a factor as following kinda close behind someone to get great efficiency, I ran 82 mph for over 20 miles at 2-3 car lengths behind a SUV and averaged 240 wh/mi. Obviously that would increase efficiency just because your car doesn’t have to work as hard to push through the air but since you always see people complaining about how there high efficiency kills their range ,just follow someone running around the same speed as you . The 20 mile trip the opposite direction I ran closer to 65 without following and was closer to 285 wh/mi. There was not really any elevation gain/ loss or winds . Temp was 75f
