“New research indicates that there may be a whole host of toxic chemicals being shed from tires & brakes that have been largely ignored until now. Even worse, these emissions may be so significant that they exceed those from a typical car's exhaust.”

Tire Dust Makes Up the Majority of Ocean Microplastics, Study Finds

Recent studies have shown tire emissions to be a larger threat to global health than anyone realized—and EVs could make the problem worse.

@ScratchinPro so the kids playgroud that uses shredded tire bits instead of wood chips might not be a good idea after all... Well, if the terrible smell of it didn't give it away.

@aeischeid Exactly.

Particulate material in the air affects negatively the learning brain.

It's just like those laminated products made with the "recycled" terrible #TetraBriks, only displacing problems to other vulnerable actors in the ecosystem.

@aeischeid @ScratchinPro Can't imagine it's all that 'good' no. But the 'dust' here is the wearing of them against the road surface. I wouldn't think that part would be particularly a problem for kids use.

Tires do however have more than a few other things about them that probably do make it a very bad choice!
