Research into Tire and Road Wear Particles (TRWP)

Tire and road wear particles (TRWP) are tiny debris produced when tires are used on the road.

Generated by the friction between tires and the road surface, TRWP are a mixture of tire tread and material from the road surface.

The Tire Industry Project has been supporting research into tire and road wear particles since 2005. TIP supported studies into TRWP include (chronological order):

  • Comparison of particles generated using different methodologies. (2010) - link    
  • Acute Aquatic Toxicity of Tire and Road Wear Particles to Alga, Daphnid and Fish. (2011) - link   
  • Evaluation of Potential for Toxicity from Subacute Inhalation of Tire and Road Wear Particles in Rats. (2012) - link   
  • Chronic toxicity of tire and road wear particles to water- and sediment-dwelling organisms. (2012) - link    
  • Use of a Deuterated Internal Standard with Pyrolysis-GC/MS Dimeric Marker Analysis to Quantify Tire Tread Particles in the Environment. (2012) - link  
  • Measurement of airborne concentrations of tire and road wear particles in urban and rural areas of France, Japan, and the United States. (2013) - link
  • Comparison of Tire and Road Wear Particle Concentrations in Sediment for Watersheds in France, Japan, and the United States by Quantitative Pyrolysis GC/MS Analysis. (2013) - link
