Tires have Carbon emissions?
Who knew? [Why do they wear out anyway?]
My question that no one has ever given me a satisfactory answer for is this. If a tire leaves a very very thin film of rubber with each revolution of the tire, where does all the rubber dust go?
The shoulder lanes of freeways and highways etc. should have 6 foot drifts of the stuff. Yet there is none. So,again, where does it all go?
