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.
- radicalbyte 6y agoThat might be right for an F1 car, they go through two sets of tires a race.

- londons_explore 6y agoParticulate 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.
