I rotated at 12K because my rears were noticably wearing faster. Your tread looks great for your mileage IMO
It's hard to tell but the tire looks lopsided (bigger on the right side on the bottom tire in picture).
Yes, by Tesla but it all they did was Take the car for a drive. The lopsidedness Appears to be the case in all tires as they won't just stand upright without being proped up underneath.
Yes, that tire thread wear looks great! Hope others can achieve similar results.

Yes, I end up lifting car 3 times on both jacks. Takes about 45-50 mins but not difficult, just time consuming.

I have only one low profile Jack, I'm hoping my regular profile Jack will fit under the car after jacking up the other side with the low profile Jack.

Get a tread depth gauge and check.
Are they all tipping over toward the heavier side (face) of the wheel?
Yes, all tires and yes, towards the face. I see what you did there when you said towards heavier side. That might be it.
Just measured my Michelin Primacy MXM4 235/45R18 98W on LR RWD at 6900 miles. Tread depth new is rated at 6.5 mm. LF averaged 6.0 mm, RF 6.0 mm, LR 5.75 mm, RR 5.63 mm. No more than 0.5 mm difference across any tread which is almost as close as you can measure. South Florida old-lady driving with a few demonstrations. Projected life prorated to 2.4 mm ( 3/32") tread depth is about 38K miles.
Incremental cost per mile $ 0.025/m for electricity at $ 0.10/kwh and $ 0.025/m at $1000/tire set at 40k miles for a total of 5 cents/mile. Ok, so maybe 6 cents.
$ 0.10/kwh is my incremental electricity cost from Lee County Electric Co-operative, a rural electricity co-op.

I'm currenly 18K miles on Pirelli P Zero Nero GT 235/40/R19 and the (even) wear is at 5/32. I've rotated three times, 45 PSI, and drive conservatively in warm SoCal conditions.
Hoping to squeeze out another 2-3K miles and then replace them with Michelin MXM4 Primacies to take advantage of the current discount prices/rebates, and also the 55K warranty. Hopefully a quieter ride as well, but overall no complaints with the Pirelli's.

Have you compared it with other tires on this car? It's the only noise you can hear and with 40+ psi in the tires road texture is very important in how much noise is made. All low rolling resistance tires have hard tread. Less effort (and expense) went into reducing road noise in the M3 compared to the S and X. Over the years I have paid close attention to fuel economy and tire wear in pure ICE cars, hybrids and now an EV. All the cars happened to come with Michelins. Experimenting with other brands led me back to the Michelin LRR all-seasons. I live in Florida so I only have one season and I understand that if you have to drive in snow you'll need snow tires. The other alternative is not to go to work when the roads are snowy and to leave early when it starts. If you're in a cushy job like that it sure cuts down on the winter accident exposure.
I did drive in NJ for 25 years, sometimes at up to 150 mph in my airliners. They had reverse thrust. Maybe the new roadster will have that.
I had one ice accident in NJ in a 1968 Volvo; slid into the back of another car at about 3 mph at an icy toll both. No damage to the othe car. They had bumpers then.

Nope. My comment is based on 15K miles on the stock tires. I do not think that for acoustic tires I should hear so much road noise.
The S and X have acoustic tires. Does the M3? There are 4 part numbers for that tire and only 1 , 16144 has acoustic lining. I can't read any part number on the outside of my tires. I don't have the acoustic logo either. I see the TO after the tire size may mean Tesla Acoustic Tech.
