Has anyone here tested the actual mileage of a 20" stock OEM vs a 22" forged wheel? Per tesla there is loss of mileage, however if both wheels weigh the same, is there still mileage loss?

Although differing wheels will have differing moments of intertia, much of this energy is potentially recoverable just like the mass of the vehicle is with regenerative braking. The problem is that the lower profile tires have greater rolling losses due to the deformations from the road contact (strain) causing greater stress (strain / sidewall dimension). Some of this is not elastic and causes internal frictional losses that are not recoverable. There are many such things like this going on in a wheel. There is also less air in the tire, which means greater compression and rarefaction with each bump - also lossy. I haven't seen a good breakdown of the magnitudes of these various effects though.
Hey there buddy, its more about the WIDTH of the wheels and tire setup rather than the Weight of the setup when you are talking mileage, there is more drag on the wider setup so therefore it will loose mileage regardless of weight. Only real benefit of the lighter wheel & tire setup is acceleration..

I will try to test fit my 20" i3 wheel and tires onto the X when it comes in LOL (I'm kinda serious tho)
I'd like to know as well. Different tires with different rolling resistance will obviously have an effect, as well as tire size and profile, and rim weight. 2 rims can weigh the same but have different efficiencies. 22" wheels have most of their weight farthest away (11") from the center axle which requires more torque to rotate than a 20" wheel as the weight is not as far from the center axle.
Tesla's disclaimer of 10-15% loss of range with the 22" wheels is huge! In my experience in the model S the difference between 19 and 21" is far less around 5%.

I'm hoping to improve the range, I purchased 20" HRE Forged wheels. They weigh 23lbs front and 24lbs rear.
20 x 9 and 20 x 11
20 x 9 and 20 x 11
Please don't, that be very dangerous. I doubt the wheels and tires of and i3 are certified to carry the 3400+ lbs per axle weight of an X.

Please let us know your experience with lighter 20 in wheels. Planning to do the same.
Op, 22 in wheels forged lightweight might have similar range as 20 if you get the same width and LRR tires.

I actually don't take delivery of the X until Saturday... will prob be running the OE 20s until Expel and Opticoat is complete. I will post weight of the wheels w/o tires for both OE and HRE.

the P Series are lighter and stronger. on my ICE cars i've had 3 piece HREs simply cuz they look so much better with a lip. Just the sheer weight savings there should be some improvement for acceleration and handling but I def didn't buy it for those two things. I just want to look good going slow (the slower the better) hahaha

Any opinions / data on 20" all season, aggressive tread, softer rubber vs 22" summer on the highway range of a Model X ?
I'm planning a road trip that needs a mid trip charge at 40 amps. Would like to keep this charge time to a minimum to get to my destination.
