Look at this thread. Look at the numbers. Literally every person reporting over 300Wh/mi average is on 20s. You're denying what's starting you in the face.
The 20s are not "low rolling resistance tires". They're sport tires. They're stickier than the 19s, which are stickier than the 18s. Suspension losses are a real, meaningful thing. Spinning wheels store a meaningful amount of energy. Non-aero wheels are an aerodynamic disaster zone. But forget about all this. Even forget about what Tesla has directly told you. Just look at the numbers staring you in the face in this thread.
Denial is not just a river in Egypt.
And meanwhile people on the 18s with aero caps average in the mid 200s and sometimes even less on the highway. depending on what speed you call "highway speeds".
The importance of wheel selection is demonstrably real.
You're making counterfactual claims about the 4S. Go talk to someone at Tire Rack. More importantly and beyond the factual issues, I'm not in denial and this style of debating is offensive.
