How much tire wear is generated every year?

According to Kole et al. 2017, based on emission data across 13 countries, the estimated global tire wear rate (excluding road wear particles) is 0.81 kg per capita per year, which translates into total global tire wear generation of approximately 6 million tonnes per year. It is important to note that tire wear depends upon multiple factors and can vary significantly depending upon the geography, the type of road or the vehicle itself – therefore this is an indicative global estimate based on the study above.
*Countries include Germany, Denmark, Italy, Netherlands, Norway, Sweden, United Kingdom, United States, India, Brazil, China, Japan and Australia.
