Car tires produce vastly more particle pollution than exhausts

Almost 2,000 times more particle pollution is produced by tire wear than is pumped out of the exhausts of modern cars, tests have shown.

The tire particles pollute air, water, and soil and contain a wide range of toxic organic compounds, including known carcinogens, the analysts say, suggesting tire pollution could rapidly become a major issue for regulators.

Air pollution causes millions of early deaths a year globally. The requirement for better filters has meant particle emissions from tailpipes in developed countries are now much lower in new cars, with those in Europe far below the legal limit. However, the increasing weight of cars means more particles are being thrown off by tires as they wear on the road.

The tests also revealed that tires produce more than 1 trillion ultrafine particles for each kilometer driven, meaning particles smaller than 23 nanometers. These are also
