Understanding Tyre Wear Particles Emissions, Pathways & Risks
What are tyres made of? Vehicle tyres are more than just rubber. In fact, natural rubber accounts for just 19% of a car tyre, with synthetic polymers accounting for 24%, fillers for 26% and additive chemicals 14%. Tyre design is optimized to deliver high performance in key areas such as safety, (wet)grip, rolling resistance, and noise reduction.
