But as car exhaust systems have become cleaner, pollution linked to heart and lung disease has increased from a different source: tires and brakes. AdvertisementScientists say the issue will only grow worse as more cars, including heavier electric cars that put more strain on tires, are put on the road. In recent years, particulate emissions from brakes and tires are starting to grow as well, even outweighing those from tailpipes in some locations. In Long Beach, brake and tires constituted 15 percent of PM 2.5 pollution, which was the same as pollution from gas and diesel. The agency predicted PM 2.5 pollution from brakes would be greater than exhaust pollution around 2020, given additional cars and cleaner exhaust policies.
