Brakes on Tesla are said to last twice as long or more. That would be a direct reduction in brake dust. Even with my Model 3 being floored from every stoplight since I’ve bought it, I’ve yet to hear the tires chirp. Suspect the tire wear is less than a comparable gas car due to the better traction control, and the harder tread in pursuit of lower rolling resistance.

All tyres are in a state of slip when you are accelerating or braking, it's unavoidable.

[jmpman]

Isn’t the purpose of traction control to keep the tires in contact with the ground in a static coefficient of friction, and thus not slipping?

[TylerE]

If there was zero slippage there would be zero acceleration.

[jmpman]

My understanding is that tires, even when accelerating, can operate in the static coefficient of friction range. And, you want them to operate in the range, because it provides the greatest acceleration. But, maybe my mental model is wrong. The following video is from someone who has considered it much more in depth.

That is a "driver's view" of tire slip (for best results, don't spin or slide the tires too much) rather than a chassis or tire engineer's view of tire slip (if you don't slip the tires, you can't generate any force).

[Robotbeat]

Not quite right? The tires have strain, but they do not have to slip on the surface.

[adrianN]

That's not very intuitive. Can you provide a longer explanation for this?

[sokoloff]

Here's a pretty decent, graspable explanation: https://physics.stackexchange.com/questions/142463/does-a-ti...

Tires that are not slipping are not creating any force against the road surface (so they don't have to slip when coasting, but will slip while accelerating longitudinally [braking or accelerating fore/aft] or laterally [cornering]).

[jmpman]

Would you say that a rubber belt on a pulley is slipping? I’m sure at a microscopic level there are some places where the belt isn’t making perfect contact and the rubber is slipping across the pulley, but at a macro level, the belt remains in contact with the pulley in the same place from when it initially contacts until it disconnects.

Well that and the regenerative braking.
