Research and analysis - Tyre ageing: its effect on material properties and structural integrity

The Department for Transport is responsible for maintaining high standards of safety and security in transport and continuing to improve road safety.

This study provides scientific advice on the effect of age on the performance of the various elements of a tyre that are critical to its mechanical integrity. The report discusses whether the material properties of vehicle tyres evolve to such an extent that the integrity of the tyre and its safety is compromised.
