In this serial number, the 18 indicates the week the tyre was manufactured, while the 8 indicates the year of the decade.So, in this case, the tyre was made on the 18th week of the 8th year of the decade.The writing and symbols on the sidewall of your tyre aren't there simply to make it look good, they all tell you something about the specification of the tyre.That includes the maximum speed at which the tyre can safely be used, the loads it can carry, its width, which way round to mount it on the wheel, where it's made and what safety standards it's passed.
If the tyres were original equipment on the vehicle, follow the vehicle manufacturer’s tyre replacement recommendations, when specified (but not to exceed 10 years).When it comes to car part longevity, however, there are always circumstances when the auto part information given by a manufacturer may not apply.In the case of tires, the estimate of how long a tire can last is based primarily on the tread wear.Old tyres can be a ticking time-bomb that could dangerously fail and lose air. Tyres are made of various types of textile, steel and rubber compounds that have properties that evolve over time.If you haven’t done so recently, it could be time to check how old the tyres on your vehicle are and if they need replacing. As the rubber in a tyre gets older and is exposed to the elements, the strength of the bond between the rubber and the steel belts is reduced.
