Tire Wear Particles and Their Role in Microplastic Pollution

Every time we drive, tiny pieces of our car tires break off and spread into the environment. These small fragments, called tire wear particles, have become one of the biggest hidden sources of plastic pollution in the world. Together, they create about six million tonnes of microplastics every year—enough to fill dozens of large cargo ships. Most of these particles end up in soil, rivers, and oceans, while the smallest ones can float in the air and enter our lungs. Tire wear pollution is now growing even faster with the rise of electric vehicles, which are heavier and cause more tire friction. These particles contain toxic substances that can harm people, animals, and plants. Yet, there are still no clear laws to control them. Tackling tire wear pollution will be essential for cleaner air, safer water, and a healthier planet in the years ahead.
