Did you know that, like fruit and vegetables, tyres have a best before date?
While they won’t make you ill like mouldy bread could, over time, a tyre’s performance can degrade and become less safe. Gradually, they turn more plastic than rubber which results in poor wet-performance and harder ride, and are prone to blowouts due to cracking as the rubber hardens. The NCT is now highlighting tyres over six years old.
Why is this? Tyre rubber is affected by air, as well as sunlight, by a process called oxidisation. It starts as soon as the tyre is exposed to the elements, and, can even happen to cars which are sheltered and driven infrequently.
Older tyres are often imported into Ireland by third parties or, bought online and sold by tyre shops at a cheaper price. While this may seem like a good deal, you’re sacrificing the quality of the tyre and your safety.
So, if you’re on the hunt for tyres, check their dates which can be found in a string of digits on the sidewall of the tyre (usually preceded by the letters DOT). The numbers represent the week and year of manufacture, for example, 2215 indicates the 22nd week of 2015.
As tyres are not made in Ireland, it can take a while for them to get here. That’s okay, as many of our tyres are guaranteed for five to ten years, if they’re transported and stored in proper conditions. This is what you’ll get if you buy from a quality, professional retail stores like Naas Tyres & Autocare.
If you are considering buying tyres that are more than three to five years old, find out where they’re from and how they’ve been stored. If in doubt, pass on them and head to Naas Tyres where we’ll make sure you get the right tyre for you at the right price.
