I hope you can see why your overly simple, absolute statements aren't very helpful for people to understand:
1) "Toe" causes inner tire wear. Never camber
2) Lack of camber causes outer tire wear., plus too high pressures.
Yet... These facts exist:
1) Model S/X cars run a lot of camber in the front, not the rear
2) Model S/X cars often see extreme innner tire wear that fails the tire long before the tread is worn. But only on the rear where there is more camber.
3) Model 3/Y runs less camber all around and doesn't see inner tire wear.
4) All Teslas run fairly high pressures.
I'm not arguing with you that toe tends to be the dominant wear on tires on street cars. But it would be helpful for you to explain to people more why this is instead of just telling them they are wrong.
Given you run a lot of camber on your "SX" - what toe and camber are you running that has led to even wear? Across how many miles?
My S and X are aligned at driveheight, auto adjustment disabled. Zero toe all around, camber in the rear on the S around the 1.5 range. x roughly the same camber, same toe settings. This is a thing with any adjustable suspension car, allowing the suspension to cycle doesn’t mean anything when you have the car set to lower at X MPH. S-30k miles, X- 15k miles, all spent towing ~4600lbs.
Our 3s are setup for road racing, but absolutely pull daily duty at well below 100mm pack clearance. Max front camber from a company’s arms that has an owner that has an absolutely crappy version of (customer) personal privacy. Front Toe zero. Rear above -2deg. Slight Toe in. Square tire sizes so they can be rotated front to back, but a 100tw tire for all track events, all seasons on the street. Flipped front to back as needed to keep wear “even” streets usually every 10k miles, Rcomps so often I don’t care to think about it. There’s a reason 16 r comps are on hand all the time, heavy car, low pressures, lots of abuse. One 3 driven 61.5k miles this way, road-tripped across the country regularly. The other has less than 5k driven this way.
It’s the internet, over simplication and blanket statements are easier than talking to a brick wall.
All bmws have experienced rear toe wear, exactly what S/X see, this is a byproduct of the company wanting their (mostly) incapable <of driving/catching a car in a slide> owners to be able to continue purchasing a new model car.
E60M5, E39M5 and most M cars are setup to chew tires and not their owners. The S/X are setup roughly the same, compounded by the air suspension and owners not disabling their auto height adjustment.
Re the pressure comment, street pressures don’t count towards my reply to your track statement.
Your 1 and 2 contradict themselves, I assume you know that.
Your 3 proves my point, in factory settings. Mine have never been factory settings under my ownership nor with my tire choice.
I’ll continue this offline with you, but my contributions to this thread will end with this post.
