The range drop between the 20’s and the 22’s primarily has to do with the difference between the tire compounds (Rolling resistance) and virtually nothing to do with the weight or diameter of the wheels . The rolling diameter of the 20’s and 22’s OEM size tires are the about the same (rear staggered tires are actually a bit taller than the fronts). I’ve changed tires to harder compounds and been able to maintain the range with 21’s and 22’s on our S’s and X. The factory 20’s come with low rolling resistance all season tires (P cars actually get Performance tires in the smaller sizes though) and the factory 22" Perrelli Scorpion tires are Performance tires, hence the range dropping with OEM tires. You wouldn’t have the same cornering abilities with higher mileage tires but if you were looking to race a Tesla they are more drag strip than road track cars anyway.
