No opposite. More traction = more friction, which leads to more energy use. The downside of over inflated tires is less control, not to mention the risk of blow out.

That's what I said (meant).
No one is arguing with that and no one is recommending it.

35 psi is under-inflated. The plate on my S85 says 42 psi. The newer cars are heavier, and might specify higher.
Correct. Mine says 45 PSI and I know if it goes lower then my energy consumption is higher, which is obvious.
Achieving 240 Wh/mi type numbers is much more readily accomplished with sparse use of HVAC. Maybe it is just because the traction drivetrain so efficient but these cars are FAR more affected by the use of heat and air conditioning then gasoline powered cars, especially heat of course (which is a combustion waste product on ICE engined vehicles.) I keep mine mostly off and average 260 or lower on a 2016 MX. I also use range mode which mostly uses the more efficient front induction motor, essentially making it a front drive car.
Industry knowledge of this issue is why most EVs, even the lowly Leaf, have seat heaters as standard equipment. I believe that this effect even exceeds that of the larger size wheels - which also cost you range.

I've found heating heavily affects the Wh/Mi, but light use of AC usually doesn't have much effect. On really hot days when the AC has to run full blast, that zaps the battery fast, but the sort of light AC usually needed around here isn't that bad.
I don't use range mode, but my Wh/Mi last summer was around 260 Wh/Mi with my MS. Doing that with an MX is impressive!

Tesla is using heat pumps in the newer models. It's my understanding that heat pumps vs the older cars with resistive heating elements is a big factor in improving efficiency.

I've seen 350 wh/mi on my 2017 P100D in the 22,000 miles I've had it for. I usually get a bit less on road trips... something like 315, so likely lots of inefficient stop / starts around town. I had the 21" staggered set until recently though, so hoping for a material reduction there.

These numbers by themselves aren't very useful. What is year and model of Tesla and driving habits. How many total miles.

Vey valid questions. Was just going to edit the post:
2022 MS LR with 450miles in summer so far.

Dang, my kwh is at 328 and I thought I was on the juice pedal all the time...
I have a plaid also... guess you like to drive faster than me!!

I was averaging 285 wh/mi over 95,000 miles. I recently replaced the tires on my 2018 75D and it's averaging 311 since the change. Hopefully it'll settle back to high 280s soon!
Plaid, 21" wheels. Lifetime average 329 wh/mi over 7k miles.
Driving style far from optimal, lot's short drives.

Mostly shorter trips. Lots of A/C and cabin overheat protection use

Cop (as with sentry mode) does NOT affect wh/mi as it’s calculated separately (phantom drain).
Wh/mi tracks driving/moving efficiency only.

Lots of A/C in Phoenix, Arizona 100+ degree weather.
I stopped driving spiritedly since I started watching my battery drain in the Summer 110+ degree weather. People get angry at me for being slow. Yeah, I'm the slow Tesla driver.
