I refer to the article on Dec 19, “Puncture-proof tyres made from plastic bottles being tested”.

As modern tyres made of synthetic rubber wear down, they produce tiny particles known as microplastics that pollute the environment. Microplastics have been found in our bodies; we breathe, drink and eat them unknowingly. Scientists still do not know what health risks these microplastics pose to our bodies.

Using recycled plastic to make puncture-proof tyres sounds like a fantastic idea, but tests should be done to make sure that the use of such tyres does not worsen the microplastics problem.
