A car tire takes around 2,000 years to decompose. Every year, over a billion tires reach the end of their life, creating one of the world's largest waste streams.
Why does it take this long?
Tires are made from vulcanized rubber — chemically cross-linked so it won't break down. As they wear during driving, they also shed microplastic particles that are now a major source of ocean pollution. Piled tires trap water, breed mosquitoes, and pose serious fire risks.

Frequently asked questions
How long does a car tire take to decompose?
A car tire takes approximately 2,000 years to decompose in nature.
Can tires be recycled?
Yes — into playground surfaces, road material, and fuel. But collection rates still lag behind the billion discarded yearly.
Are tires a source of microplastics?
Yes. Tire wear is one of the largest single contributors of microplastics entering rivers and oceans.
Sources and methodology
Decomposition times are approximate and vary substantially with material composition and environmental conditions. See the methodology and primary references used for this guide.
