Many drivers focus on tyre pressure and tread depth but overlook one crucial factor — the tyre’s expiry date. Tyres don’t last forever, and using expired ones can compromise safety, grip, and performance. Knowing how to check your tyre’s expiry date helps you replace them in time and avoid potential blowouts or accidents. Here’s how you can easily find out when your tyres were manufactured and when they should be replaced.
- Locate the DOT Code on the Tyre
Every tyre has a DOT code (Department of Transportation code) printed on its sidewall. This code provides essential information about the tyre, including where and when it was made.
- Look at the sidewall of your tyre — the outer rubber surface that faces you.
- Find a series of letters and numbers beginning with “DOT.”
- The last four digits of this code represent the manufacturing date.
For example, if the code reads DOT X2AB 2319, the tyre was made in the 23rd week of 2019. This means it was manufactured around June 2019.
- Understand the Tyre Manufacturing Date
The first two digits of the last four numbers show the week of manufacture, while the last two digits show the year.
- Example: 4520 means the tyre was made in the 45th week of 2020.
- Example: 0118 means it was made in the 1st week of 2018.
Knowing this date helps you estimate how old your tyres are, even if they still look new on the outside.
- Determine the Tyre Expiry Period
Most tyre manufacturers recommend replacing tyres every 5 to 6 years from the date of manufacture, regardless of appearance or tread condition. The maximum lifespan is about 10 years, including storage time before installation.
If your tyre was made in 2018, it’s best to replace it by 2023 or 2024 at the latest. Environmental factors such as heat, sunlight, and road conditions can accelerate wear and reduce tyre safety even earlier.
- Check All Four Tyres
Each tyre may have a different manufacturing date, especially if they were not bought together. Check the DOT code on all four tyres — front and rear — to ensure none are older than recommended. Replace any tyre that has passed the 5–6-year mark, even if it still has visible tread.
- Inspect for Signs of Ageing
In addition to checking the expiry date, inspect your tyres for signs of ageing or damage. Look out for:
- Cracks on the sidewall
- Bulges or bubbles
- Uneven tread wear
- Dry rot or fading
If you notice any of these issues, it’s time to replace your tyres immediately, regardless of their age.
- Ask Your Tyre Dealer for Assistance
If you’re unsure how to locate or read the DOT code, your tyre dealer or mechanic can help. They can also tell you if the tyres in stock are recent models. Ideally, when buying new tyres, check that they are not older than 12 months from the manufacturing date.
