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.

Yet another video about static coefficient of friction on tires that aren’t slipping. Electric cars are more easily able to keep their tires in this maximum static coefficient of friction range, maximizing acceleration.

At a micro level, I would say that a rubber V-belt on a pulley which is transferring significant force is slipping as an unavoidable element of delivering that force.

What traction control/ABS does is keep the the tire slip ratio in the right range to optimize acceleration. https://www.researchgate.net/figure/Typical-tire-longitudina...

What we intuit about whether or not we're slipping our tires every time we brake for and then drive away from a traffic light "without slipping them" is not actually correct at a micro level. With respect to this thread, it is the micro level that is relevant to tire wear and resulting particulate emissions from that slippage.
