Emissions Analytics found that emissions of particulate matter from tire wear can be 1,000 times worse than from tailpipes. https://www.greencarreports.com/news/1127424_study-particulate-emissions-from-tire-wear-is-higher-than-from-tailpipes https://www.greencarreports.com/news/1127424_study-particula... This is a rapidly increasing problem as more EVs, which are very heavy on tire wear, generate more pollution. Good idea to stay on top of alignment: https://teslamotorsclub.com/tmc/threads/unusual-tire-wear.108481/ https://teslamotorsclub.com/tmc/threads/unusual-tire-wear.10...

That study is utter nonsense: > 5.8 grams of particulate matter per kilometer Red flag. What kind of contrived conditions did they conspire to create that number? And with regard to Tesla vehicles being heavy, that’s obviously fixed by using wider tyres or harder tyres, in order to get the requisite traction.

Is it EVs that are heavy on tyre wear, or Teslas specifically? I've not heard issues from the Outlander, Zoe, Prius and Leaf drivers I know, and we talk EVs regularly.

  I think when you have more torque under your control, you're more tempted to use it, and even a tiny amount of tyre skidding makes a lot of dust. Also, EV's are heavier so will break up the road surface much faster - various studies have shown doubling the weight on a wheel far more than doubles road wear.

  There's a lot of data about specifically Tesla being hard on tires, with owners recommending regular alignment to preserve. Doesn't matter if it's a diesel 18 wheeler or an ev though, tire wear is a v major contributor to air pollution, my primary point which was downvoted. I wonder if some sort of air ground effects might alleviate this, like a hovercraft when safe to apply?

>The hatchback's tires emitted 5.8 grams of particulate matter per kilometer This number seems incredibly suspect. It's far too high. That rate of loss cannot be sustained. Either their research is wrong or loss levels off dramatically and quickly. At that rate of loss the tires, across 4 tires at 27 lbs each, would evaporate in 8500km and realistically be unusable after under a thousand.

  That might be right for an F1 car, they go through two sets of tires a race.

    It says “hatchback”, so: no?

  Particulate matter might not come entirely from the rubber of the tyre. Parts of the road surface are also broken up into fine dust and sent airborne. Tar from asphalt doesn't sound great to have in lungs, nor does sillica dust from aggregate/concrete. Looking how quickly potholes form, I could totally imagine 5 grams of loss of road surface per kilometre.
