It’s at least a 10% range hit. Usually more in the 13-15% range. And the 22’s come with summer tires; no bueno here in NJ.
And yes - the 22s are low profile rubber bands - the 20” tire sidewalls are almost 30mm taller. That’s the different between a cracked rim and a hard bounce.
I’m not a fan of the 22s. Go before show, for me.
I appreciate this information, can you provide some reference to support this?
I find 15% range hit, even 10 % due to wheel difference very hard to believe.
Here's why:
The vast majority of resistance to forward motion comes from the cross sectional area presented when looking at the vehicle head on. This area has to 'push' air out of the way and this takes energy. Take away the need to push air out of the way, and we'd be looking at ranges of 2000-4000 miles on flat ground.
This is the very reason that the X has lower range than the S. It has the same width, but greater height. thus the 'area' presented when looking head on is greater. All else is approximately the same, motors, battery etc... 402 range for the S, 351 for the X..... talking LR versions of the 2020's.... the 'range hit' due to the increased vertical dimension of the X ( and probably the greater ground clearance as well). is 402/351 = 15% .
So
- Range difference between Model X and Model S = 15%. ...Yes
- Range difference between Model X with 20" wheels and Model X with 22" wheels = 15% ......?????
so if a complete change in the structure of the vehicle: many additional inches of height and greater ground clearance, result in a 15% range hit, how can you in good faith make the statement that merely changing the wheel geometry would result in a 'range hit' of a similar magnitude?
The wheels themselves only change by 10%, so assuming that the air Ingress / turbulence created around the wheels accounts for 10% of the total air resistance, then this change would have a .10*.10 = 1% range hit.
Ride height would be higher by 1"...so this could be a factor, but again, not a 15% change maker
I also do not think the engineers at Tesla would have approved the use of wheels which decreases the range by 15%.
I can drive with the two front windows down and don't even see a 5% range hit. So ingress of air into the wheels causing turbulence does not make sense to cause such a substantial range hit, to me.
