We're all used to the concept of higher taxes for cars with the highest toxic emissions.... could tyres be next?
The Government has commissioned a report into the impact of emissions from different types of car tyres.
It could lead to a 'ranking' of tyres with those which wear out fastest, leading to a higher amount of particles and emissions, costing more in tax despite being usually cheaper to buy.
The RAC has warned it could lead to more people driving around with illegal tyres instead of buying cheap, new ones as they look to avoid paying higher tax.
According to Imperial College London, more than six million tonnes of tyre wear particles are released globally each year, and in London alone, 2.6 million vehicles emit around nine thousand tonnes of tyre wear particles annually.
Will it, I wonder, lead to car tyre manufacturers promising 'miles per tyre' in the same way that we measure MPG?
