BTAS includes:

• Wear rate and particle size distribution: Measuring how quickly tyres wear in real-world driving and breaking down the particles into meaningful size categories, from coarse fragments to fine and ultra-fine particles.

• Chemical composition analysis: Understanding what tyres are made of, how materials differ across brands and models and which chemicals are released during wear. This forms one of the most detailed tyre chemistry databases available anywhere.

• BTAS data products: Including Tyre Insights, our quarterly reporting series and subscription access to the full BTAS database for in-depth research and benchmarking.

Together, these datasets allow researchers, regulators and manufacturers to see the true environmental footprint of tyres.
