I see a new feature in 2021.44.5 to detect uneven tire tread depth. Question, it you run tires that are not factory specification (I have 245/40/19 and they exceed factory specs) will this cause false warnings?

I'm guessing that the new feature measures the rotation of the 4 tires against each other and detects any mismatches. As long as your 4 tires are the same size (same diameter), it shouldn't matter what size they are for this feature. Of course, you will still need to rotate the tires front to back if your tread depths start drifting otherwise the car will detect the difference in rotations over time between the front and rear tires (especially if your car is RWD).I see a new feature in 2021.44.5 to detect uneven tire tread depth.

An important piece of equipment. Right up there with a torque wrench.I got this update several years ago ...

Seriously though, I like the idea of an extra, more active system, that might bring your attention to an alignment issue that's wearing one tire quicker.
I'd assume Tesla has lots of data on hand to be able to have a baseline, though like @Shelburne said, lots of variables, including the specific tire you're using (vs. OEM).
Depends on the radius of the circleI like this feature.... but
If I drive in circles, how long before I get a notice of tire rotation difference?
The car has a steering angle sensor, so it probably takes that into consideration in it's calculations. But it might only monitor stretches of straight driving and ignore turns.Depends on the radius of the circle
Do you drive on highly cambered roads?well i can say this, i believe this system is warranted.
hankook RS4's 265 on 18x9.5s with only 5-6k miles on them(stock suspension and aligned when installed)
aggressive daily driving
rear right is bald(5 miles of life left)or(one trip to Electrified Garage)
rear left is just at wear bar(1,000+ Miles of life left)
fronts not that close to wear bar yet.(2-3,000 or more Miles of life left)
i either take way more left hand slides or the right rear axle is getting more power more frequently and slipping more?
im very confident there is either an issue in the dif, alignment, or my preference for left hand turns lol

This is the type of using data for good that I really appreciate as opposed to the use of data for evil exhibited by certain social media companies.
I'm not familiar with companies who do this, let me search Google for some information ...
What will it do when you put on tire chains?
So I changed my rear tires around xmas, but did not change the front ones. Now I'm getting this message: "Uneven tire wear - rear tire tread depth too low". Edit: I would expect "front tire tread depth too low" instead, as they are older...
It seems to me that the same message pops up as soon as they detect a difference between the front and the rear tires. They seem to assugn the rear tires to be more worn out.
Hi Mike, the front tires have almost 28000 miles. They can probably make another ~5000 miles maybe. So worn out but not to the point that I want to change them yet. But my front tires are like only 3000 miles. Yeah I had to bring it to the Tesla Service center for another message "Camera occluded", so I mentionned this too.So are your front tires really worn out? If so, you should report the issue to Tesla so maybe they can correct the warning. (Maybe they should leave the front/rear part off the warning if they can't properly identify it.)
