Emissions Analytics has found that adding 1,000 pounds to a midsize vehicle increased tire wear by about 20 percent, and also that Tesla’s Model Y generated 26 percent more tire pollution than a similar Kia hybrid. EVs’ more aggressive torque, which translates into faster acceleration, is another factor that creates more tire particulate mile for mile compared to similar internal combustion engine cars.
