Aging Tyres

The average life of front tyres on a front wheel drive car is around 20,000 miles, or about 2 years for the average commuter. The rears will last up to twice as long with careful driving, though they can be rotated onto the fronts when necessary. This means that your unlikely to have to worry about the tyre compound degrading before the tread is worn to its legal limit. However, seldom used vehicles, such as a prized sports car or perhaps a trailer or caravan, may not see their tyres replaced due to wear over a much longer period.

Tyre rubber degrades over time, particularly when tyres are not used and have no heat put through them. Tyres that have degraded in this way may become cracked and discoloured and they are at risk of blowing out, which could cause a fatal accident at high speeds. It is recommended that tyres over 10 years old be replaced, regardless of wear (tyres never used and kept in storage may degrade even faster than this). To find out the age of your tyres, look for the last four digits of the DOT code on the sidewall. These give the week and year of manufacture.
