Shear forces cause a high number of tyre particles to be released. Heat builds up on the tyre's surface, causing hot spots that reach temperatures high enough to allow the volatile content to evaporate, resulting in the emission of relatively small, submicrometer particles. Shear forces and heat in the rubber cause road wear particles to cling to the rubber wear and tear in addition to tyre wear and tear.
