Means to an end
Legislation relating to tyre tread wear is well established but the time beyond which a tyre should be discarded as unsafe is less clear. Tyres are coded with the DOT tyre identification number which identifies where and when the tyre was manufactured. The rate of deterioration is dependent on light, temperature and humidity and how the tyre is stacked during storage. Ageing in service is suffered by the tread in the form of wear. A six-year lifespan is generally recommended by car manufacturers. Within the Tread Act 2000, the US congress asked the NHTSA to examine tyre ageing using a peel test, the Michelin durability test and an oven-ageing test. ASTM and SAE committees are also studying tyre ageing. Legislation relating to the performance of new tyres exists, but the only legislation relating to worn tyres concerns minimum tread depth. The market for used and part-worn tyres is not controlled in the developed world.
