Does tyre age matter? Yes.
The team at Bud’s Tyres are here to answer all of your tyre age safety questions. Tyre age is crucial to your safety and the safety of your passengers. Tyres should be replaced if they were manufactured more than 10 years ago with new tyres. Retailers are not permitted to sell tyres if they are 5 years old from the date of manufacture. Tyres are considered new for up to 5 years from the date of production. If the minimum tread depth of 1.5mm has not been reached they will still need to be replaced after 10 years. Furthermore, if they are still functional when driving and appear to be in usable condition they will need to be replaced. We recommend old tyres are replaced from 7-10 years after the date of manufacture.
While most of us have never seen our tyres last 10 years there are a number of individuals who do reach that 10 year mark. For example car owners who travel very short distances with premium tyres on perfect road conditions may get their tyres to the decade mark. If you seek alternative methods of transport or find yourself with a ‘weekend’ or ‘hobby’ car or trailer you may also be one of these individuals. This rule includes your spare tyre. Regardless, it is important to know. Whilst there is no legislation in Australia to govern tyre age there is an elusive used-by-date that all tyre retailers follow based on the guidelines of tyre manufactures. It is beneficial to make note that new tyres may range from a few months to several years before purchase. This is not uncommon.
How old are my tyres?
All tyres sold for use within Australia must be approved by the Department of Transport and will contain a tyre identification number detailing a number of things including date of manufacture. This sequence of numbers will be found on the tyre sidewall and contains the week of the year and year. For example the code ‘1221′ will outline that the tyre was made in the 12th week of the year 2021.
Signs of tyre age
Tread depth is often used as a guide as for when tyres should be replaced. However, your tyre may actually deteriorate quicker with age. Tyres are made of different rubber compounds and materials such as steel. Due to the oxidation process, rubber is exposed to oxygen it will start to crack as it dries out. Cracks will begin to form beneath the surface but may also appear on the external surface. The rubber and steel bond may be compromised or the steel and rubber can separated from the tyre. This is even more relevant when the tyre is placed under load. In Australia the heat can also speed up the ageing process. If you find yourself inflating your tyre more frequently this may be a sign of tyre age and subsequent tyre failure. Spare tyres and tyres that have been store or used irregularly may perish.
