New Study Shows "Pollution from Tire Wear 1,000 Times Worse than Exhaust Emissions"
If a typical set of cheap tires lasts 50,000 km (30,000 miles) then according to this study they would emit 290 kg (640 lb) of pollution over the life of the tire. Google says a light car tire weighs 20 lb (9 kg). There's a conservation of mass issue going on here.
Could it include bits of the road? Maybe, but I don't think that's what they're saying.
Yeah I didn't understand this part as well.. What exactly do they mean by 5.8 grams of particles? Are you sure they didn't mean 5.8 milligrams?
I think this part explains why this is a severely non-representative experiment:
Something doesn't add up. If tires last around 50,000km and they are emitting 5.8g/km in particulates. That would be 290kg thats over 600lbs of particulates. Huh? I must be missing something.
Based on this image, they seem to imply that road dust is part of the factor.
