In early 2020, UK-based independent testing firm Emissions Analytics published a study claiming that tire particulate wear emissions were 1,000 times worse than exhaust emissions ( earlier post ). As a result, distance-specific mass and number emissions can be derived, which can then be compared to equivalent tire metrics.
