Do Tyres Have Expiry Dates?
Like many products, tyres have a lifespan and don’t last forever. Over time, they naturally degrade, making older tyres a potential safety hazard on the road. Below the surface, as tyres age, they can develop cracks, weakening their structure and possibly leading to failure when under stress. If it’s been a while since you last checked, now might be a good time to evaluate the age of your tyres and consider whether they need replacing.
How to Determine the Age of Your Tyres
Finding out how old your tyres are is crucial for maintaining safety. You can determine the age by locating the Tyre Identification Number on the tyre’s sidewall. This number typically follows the abbreviation “DOT” and includes a series of 10 to 12 digits. The final four digits of this code indicate the week and year the tyre was manufactured. For example, a code ending in 1820 means the tyre was made in the 18th week of 2020.
The Risks of Aged Tyres
As tyres age, the materials they are made from begin to break down. Rubber, when exposed to the elements over time, loses its flexibility, and the adhesion to the steel belt within the tyre decreases. This can lead to visible cracks on the surface or, worse, hidden cracks within the tyre that are not immediately apparent. These hidden dangers can suddenly manifest as serious issues while driving, with the potential for the steel belts in the tread to separate from the rest of the tyre.
When to Replace Old Tyres
Replacing tyres every ten years is recommended, regardless of their visual condition or tread depth. However, many tyres may need to be replaced sooner due to various factors. It’s essential to conduct regular checks for signs of wear, such as cracks, bulges, and tread wear. Additionally, a professional should inspect any performance issues like increased air loss or unusual noises. For optimal safety, any tyre over five years old should be examined by a tyre expert annually.
Safety First
If you’re unsure about the condition of your tyres or how old they are, visiting a professional like Mobile Tyre and Auto Team for a thorough inspection is advisable. They can provide expert advice and services to ensure your tyres are safe and roadworthy.
Remember, maintaining good tyre health is not just about prolonging the life of your tyres but also about ensuring your safety and that of others on the road.
