Little relevant information was available regarding the effects of ageing on heavy vehicle tyres, either from the literature, from fleet companies or from the retreading industry.
Nevertheless, some members of the industry (Continental/Uniroyal/Michelin) have published
recommendations on the maximum age of a tyre in use; as do the BTMA in relation to retreading age limits.
The test programme identified an increased tyre rubber compound stiffness with age, with an associated reduction in elasticity with increasing age.
