Are those 19" snow tires? Brand?
Regardless, I don't see any wear on the inside sidewall so I guess they're fine?
They are the T0 marked Pirelli PZero Winter in 21" OEM size.

Interesting and very informative photographs. I hope others with the 21" Pirelli tires will provide pics of their tires as well.They are the T0 marked Pirelli PZero Winter in 21" OEM size.

Im interested in the fact that you mention 20" tires. On my plaid I've had 20" TSW's since about 500 miles. The car has about 14k on the clock and all four of my 275/35/20 PS4's are wearing perfectly evenly, no shoulder wear whatsoever. I am able to rotate every 4k, but in doing so, there is absolutely no shoulder wear.Sidewalls on 19s are softer than sidewalls on 20s which are softer than sidewalls on 21s. I think any alignment problems will show up more on wheels with stiffer sidewalls since they don't flex as much.
Prior to installing camber & toe arms, 20s on my car wore out the same way as the 21s except the wear band wasn't as narrow. it was wider, spread out more.
Your tire sidewalls are taller plus they're skinnier, so the geometry is significantly different. i.e. you have move sidewall flex + the pinch point on the 21" OEM setup is further inward than you now have. That's why you're not seeing anything strange.Im interested in the fact that you mention 20" tires. On my plaid I've had 20" TSW's since about 500 miles.

Do you have photos of you 20's?
Yeah, that's why Im asking @Russell why he's indicating that his 20" were showing sidewall shoulder wear.Your tire sidewalls are taller plus they're skinnier, so the geometry is significantly different. i.e. you have move sidewall flex + the pinch point on the 21" OEM setup is further inward than you now have.

What's your offset and width of those 20"?Yeah, that's why Im asking @Russell why he's indicating that his 20" were showing sidewall shoulder wear.

No Lucid not mine. My detailer had it and wanted to do a photoshoot with both cars. TBH I was totally unimpressed with the lucid, but I've had Model S since 2014 and I love them.Wheel width?
Lucid is yours too? If so do you prefer one over the other?

No, my suspension is stock, I drive the car in low 100% of the time (except when it auto-raises)Did you install adjustable camber and toe arms?
Mine are staggered so I can't rotate.

Tesla's excessive negative rear camber is only 10-20% of the tread problem, and is non-adjustable on stock camber arm. Excessive rear toe is 80-90% of the tread problem, and is also non-adjustable on stock toe arms. Then, heavy acceleration forces the entire rear subframe to move forward, further increasing the already huge rear toe, and no wonder the tires disintegrate.If you have a heavy foot and love to drive the car hard, the constant load on the rear end under torque causes the car to squat which leads to heavy negative camber under load.. this in turn focuses the contact patch to the inner tire wall and eats them away.. No factory alignment can sort this..
The factory toe arms are already adjustable, you don't need to buy those.Tesla's excessive negative rear camber is only 10-20% of the tread problem, and is non-adjustable on stock camber arm.

Tesla's factory alignment specs are complete garbage. There are no other production vehicles that spec 0.18 degrees of toe as an allowable value, yet every post in this thread that says "Tesla did my alignment" has attached a picture showing Tesla has their rear toe at 0.18 degrees, unacceptable.
Model S/X drivers with 21s have only 2 options:
1. Replace tires every 5-10k
2. Install aftermarket adjustable camber and toe arms, and correct the alignment to sensible specs instead of Tesla's junk specs.
As @Sam1 has already explained, 19s are much less (but not immune) to the bad alignments because of greater available sidewall flexing.
Anyone that doesn't believe this? Let me run your 21s on my Model S with aftermarket arms and corrected alignment. I drive like a bat out of hell, but I'll still get 30k out of your 21" factory Michelins (because I've got 45k on my tires already, with more remaining). I'm running -0.4 camber and +0.02 toe on all 4 corners.
Has anyone purchased the alignment kit from N2itive to address this issue?
Or you can get any forged design of 100's in any size and spec and color from jova, and they don't run specials because they're always cheap.Martian Wheels is running a special on its forged 20” wheels for the Plaid. Excellent price in case someone was on the fence about switching over to 20s
That’s true. Jova wheels is quite interesting. Irrespective, I firmly believe the only way out of the 21” tire problem is to move away from 21 altogether.Or you can get any forged design of 100's in any size and spec and color from jova, and they don't run specials because they're always cheap.
