This is not true at all. My daily driving 2013 EV with 90k miles still has the original tires and brakes. There's no oil to change and only a handful of mechanical components. The only think I've had to service is the 12v battery.
You can get an 80K mile tread warranty, and you can use tires beyond warranty. Of course, that is in no way specific to the powertrain of the car (unless you're using your powertrain to do burnouts...)

I have a mode 3 and with regenerative breaking you end up using your breaks a lot less.
Commuting on glass smooth roads and driving with an egg under the throttle I can see 100k.
I'm not trying to dispute what's being reported, just wondering about what tires they put on that would last 90-100K.
Tesla is an odd beast because they staked their reputation on performance and kind of actually have to back it up. And they chew through tires about as fast/slow as any other performance sedan. Or at least that's my impression. Tesla stuff is 10yr and a couple tax brackets outside of what I usually deal with.
I imagine tires on a tesla would need to be serviced like any other sports car as they are definitely NOT using the sort of thing you'd find on a volt or leaf. My car came with "special" ev tires that are super hard and are inflated to 36 psi. My understanding is that a lot of the non sporty EVs have similar tires.
