I finally got the MXM4 tires on the car and was able to do some distance runs, went from 345 on the 4S tires to 300wh/mi on the MXM4. Both sets were at 45psi. Big difference in tire noise as well, very quiet on the MX. Both sets of tires are 235. There is a big jump when you go from 65 to 75.
Don't think the 19 versus 20 would make any difference. FWIW the MXM4 tires were mounted on the 19" rims.

To my knowledge my MXM4 tires do not have the foam lining, I was not aware that they made them with the lining. My S with the Goodyear Tires do have the foam lining. I looked on tirerack and could not find a LRR spec for the Michelin.

The MXM4 tires have a lower roll resistance than the 4S tires, you give up some grip for mileage as well as being able to drive in cold weather.
I got some 18x8.5 flow one from tire rack. The stock 18in tire fits and they look pretty good. No spacers needed and it clears the brakes.

If you look at the TireRack MXM4 here, it specifically calls out Green Focus and Tesla acoustic spec. I learned recently that within a particular model of Tire, OEMs can have special formulations so there can be huge variation even within the same tire line up. That's why I'm aiming to get 18" rims for my spare set so I can get the Tesla spec LRR tires with foam.

I've seen videos where you can easily patch a tire with foam, by simply removing the foam in the area that needs to be patched. A more understandable issue is the fix-a-flat goop that comes with certain tire inflation kits supposedly don't work as well if at all with the foam in the way.
On the main topic, I was looking at all the MXM4 variations on TireRack and they all have the "Green Focus" as part of the description so I assume its a LRR tire regardless of OEM spec.

I’ve been searching for 9.5-10.0 rims that will fit the P3D+ without a spacer. Has anyone found a rim that will work? If I can find the rims I’m going to put r88r 275/35/19 or 20 tires on and take it to an autocross event next month. Any help is appreciated.

How does the energy usage change for you? I'm also looking to get some 18s for the winter and hope it helps compensate for the loss of range from the heater.
I can help as i'm also looking for a set of autocross wheels for my P3D+. It will be tough to find something in 10" width with +35 offset for 275's, i know that Mountain pass is currently running that size (square) on their RWD car but they report very little (if any) clearance to the suspension and the P3D+ has 5mm thinner rotors, so that won't work. You might be able to do something like a 19x10 +30 but not positive.
I'm personally going to order some 19x9.5 +33 wheels with the hub machined to fit over the lip on the P3D+. There are a few places that can do this, i'm currently looking at getting some V710FF from VMR Wheels and can report back in a few weeks. Planning to run 265's on them.

297Wh/m with the new wheels on the first charge after about 100 miles temp in the 50s and 60s. I didn't pay attention to what it was with the 20s.
Yes they will. I will certainly report back with how it goes!

That was with the wife driving, she grew up in South Florida. I would expect lower than 250. We had a rwd and I think I would see as low as 195-220 in ideal conditions.
