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.
I got rid of the Bridgestone dullers (on the drive wheels) it did improve my MPG by a lot..

swapped them out with Michelin energy saver about 10 pounds lighter in weight.. gave me a big boost in MPG.. from 25-27 on the highway to 27 to 31.5 on the highway
