EVs can be pretty bad for tire wear, not just due to vehicle weight, but the amount of torque available (and consistently available) that leaves most ICE vehicles in the dust. Depends on driving style of course
If you have an EV and you care about health and the environment, use regenerative braking as much as humanly possible. Hint: driving fast or tailgating both increase the odds you'll have to use the friction brakes.
I always assumed EVs use regenerative braking as much as possible on their own.
I wonder if this will spur mandatory regenerative braking in all cars, eventually, as a means of reducing pollutants?
Maybe, but that still isn’t solving the root of the problem. There are a ton of ways in which cars harm us — exhaust, brake dust, tire dust, etc. The only actual solution is to reduce car usage.
Why can't we have both?
Until we do convince uncle Jack and his friends to stop voting for things against humanity, at least those things could be made less harmful
Regenerative braking has much less tire wear than traditional braking because it's done much more slowly and smoothly. Also, none of these discussions use up-to-date information on EV tires. Consumers aren't willing to replace their tires much more often for an EV except at the high end of the market, tire manufacturers are already making tires last much longer for EV purposes. New designs are already shedding less d…
Regenerative braking has much less tire wear than traditional braking because it's done much more slowly and smoothly. Absent any evidence, I don't believe that claim. Unless you're skidding, I don't see how braking slowly and smoothly over a longer period causes any less tire wear than braking more rapidly for a shorter time. Additionally, since this is intrinsically tied to EVs, they weigh more and thus increase ti…
The same exact reason that accelerating quickly causes far more tire wear than accelerating slowly, only in reverse. By applying more torque to brake/accelerate, you cause more lateral force on the tires (think, smearing the rubber itself) which is what causes tire wear. With more force the rubber is stretched further, which fatigues it and breaks off pieces of it over time.

Sounds like emission standards need to be updated to include everything coming off a vehicle, not just out of the tail pipe. It would incentivise clean disk materials and regenerative braking.
Emissions standards have been deleted. Finally. I'm convinced they were going to greatly increase the environmental issues. After having improved emissions for decades they had no where else to improve and started building really complex engines with extreme maintenance requirements and very low reliability compared to the late 1990s. Modern trucks are throw aways compared to mid-1990s Ford and late 1990s GM. Nissan went out of business and Toyota isn't much of a player for towing capacity and value. Stellantis products have been a joke for years except for maybe the Charger and Wrangler for a time. Lots of high dollar junk being foisted on consumers right now.
The Yale article and the paper both highlight the fact that EVs use regenerative braking and produce less dust. I was worried that this was a rehash of the astroturf campaign from a few years ago focusing on EV weight and how that was so bad for the environment because of tire and road wear. Unfortunately you need to read through the whole thing (instead of the headline and a few paragraphs) to see that information.
Just a note. If the manufacturers can get solid state batteries to the point where they are economic then EV's will be as heavy or perhaps lighter than gas cars. Actually a 50% increase in energy density is enough. And solid state batteries have twice the energy density. So likely lighter.
Jevons paradox says cheap EV's are maybe not so great. Consider if a cheap car cost a $100k most people wouldn't own cars. They'd walk or take the bus or subway. You wouldn't usually have to walk far, buses and subways would come often.

They do. But if you brake too agressively, they switch to friction brakes. It pays off to avoid this: more mileage, marginally lower charging expense, lower cost on brake maintenance and fewer complaints from passengers.
