"..part of the issue is that the Tesla version of these tires start with 1.5 32nds of an inch less tread depth than the off-the-shelf MXM4s. Although it might not sound like much, that's 20 percent less usable tread depth. "
that's a pretty shitty way to cut costs if that's true; they should at least give the 'tesla version' of the tire a new designation -- at least then it wouldn't look like an obvious attempt to hoodwink consumers.
a charitable take would be that they're shaving tires[0] so that their car has better tire performance , and that this process is actually costing Tesla money... but I somehow doubt it -- and if that IS the case the tire should still be re-designated given that a third party is taking it upon themselves to modify the rubber.

- vsskanth 5y agoThey aren't shaving tires. OEM tires are specifically designed for the vehicle and come direct from factory. Reduced tread depth is mainly for meeting rolling resistance targets and to increase EPA range. Source: I am in the automotive industry
- post_break 5y agoThey do this for motorcycle tires too. Tires normally made in one factory, tires “stock” made in a different factory like Brazil with much less tread.
- epistasis 5y agoThat's weird, I'm at 25k miles, my model 3 tires are pretty close to new, and ICE drivers have commented that the tire treads look good. I'm not a tire expert, but I've heard that there are huge differences in tire longevity, and for people that live near water should be using the higher longevity tires to reduce microplastics. And if you live in the SF Bay Area, the microplastics in the ocean are mostly tire microplastics, not straws or bags or beads in shower gels.
- kova12 5y agoRegenerative braking saves a lot of brake pad material at the price of increased wear of tires. Additionally, tires are formulated for energy savings at the price of longevity. In other words, it's normal that they wear off fast
- booi 5y agoHow does regenerative braking increase wear on tires? I imagine the forces are the same to the tire.
- cptskippy 5y agoHow does bake Regen wear tires more thab regular braking?
- scottLobster 5y agoI could see a situation where regenerative braking is generally more "grabby" than traditional braking, and so would result in generally more short stops/more intense pressure on the tires per stop, which over time would lead to increased tire wear
- cptskippy 5y agoBut regenerative braking isn't as hard as normal braking. If you relying on it you will generally have longer braking distances.
