860 miles? That sounds too optimistic to me.

Offroad tires have really freaking high rolling resistance because tread hysteresis. I recall looking at some tire RR list some number of years ago. Most passenger tires were in the 0.006-0.012 range, but some offroad tire stuck out like a sore thumb at 0.017.

Just looking at the Tesla, I think the wheels are going to contribute way too much drag to hit 0.30 Cd. Maybe miracles happen though.

I think Elon's range targets might be hit with some special street-friendly tire, and the people ordering the knobbly tires are going to be pretty disappointed with the range.
