The age limit exists because rubber degrades with time and heat, even when the tread still looks deep. UAE conditions accelerate that ageing. Knowing how to read the code lets you check the tyres already on your car, judge a used car before buying, and confirm that new tyres you pay for are recent stock rather than old inventory.
How to read the DOT date code
The DOT code is a string of letters and numbers starting with DOT, and the date is always the final four digits, usually inside a small oval. The letters before the date identify the factory, the tyre size code and the manufacturer's batch, and they do not affect age.
Read the four digits as week then year. 0122 is the first week of January 2022. 3524 is week 35 of 2024, roughly the end of August. 5223 is the last week of 2023. The full code is often printed on only one side of the tyre, so if you cannot see it, look on the inner sidewall facing under the car, using a torch.
- 2423 = week 24 of 2023 (mid-June 2023)
- 0122 = week 1 of 2022
- 3524 = week 35 of 2024 (late August 2024)
- A three-digit code means the tyre was made before 2000 and must be replaced
The UAE five-year practice
In the UAE, tyres more than five years past their DOT date are commonly rejected at vehicle inspection, so drivers should plan replacement before that point. Using the example above, a tyre coded 2423 reaches five years in June 2028.
The limit reflects UAE technical standards for tyres and the inspection practice at testing centres approved by the RTA in Dubai and the ITC in Abu Dhabi. Inspectors look at the DOT code alongside tread depth, cracks and damage. Because policies and their enforcement can be updated, treat five years as the practical maximum and replace earlier if a tyre shows cracking, bulges or hardening.
| DOT code (last four digits) | Manufactured | Reaches five years |
|---|---|---|
| 0921 | Week 9, early March 2021 | March 2026 |
| 3822 | Week 38, September 2022 | September 2027 |
| 2423 | Week 24, June 2023 | June 2028 |
| 1524 | Week 15, April 2024 | April 2029 |
| 4725 | Week 47, November 2025 | November 2030 |
| 1226 | Week 12, March 2026 | March 2031 |
Why tyres age faster in UAE heat
Rubber ages through oxidation, and chemical reactions roughly speed up as temperature rises, so a tyre that spends its life on 60–70°C roads and in direct sun ages faster than one in a mild climate. The protective waxes and oils in the compound are used up sooner, and the rubber hardens.
A hardened tyre can look fine but grip noticeably less, especially in the wet, and its sidewall becomes more likely to crack under flexing. This is why tyre age matters as much as tread depth in the UAE, and why a low-mileage car can still need new tyres.
How to make sure new tyres are fresh stock
When buying new tyres in the UAE, check that the DOT date is recent, ideally within the last 12 months, before they are fitted. Tyres stored correctly in a warehouse age slowly, but every month on the shelf is a month taken from their legal working life on your car.
Ask for the manufacture date before you agree on a price, and check the code on each tyre when it arrives, since one set can include different batches. A tyre that is two or three years old at fitting will reach the five-year point much sooner. Reputable suppliers rotate stock and will tell you the date openly.
- Ask for the DOT date before paying
- Prefer tyres made within the last 12 months
- Check every tyre in the set, not just one
- Be wary of large discounts on old stock
Checking the age of a used car's tyres
On a used car, tyre age is a quick way to judge both safety and upcoming cost. A car whose tyres are four or more years old will need a new set soon, which can be a significant expense on large SUVs or performance cars with 20-inch wheels.
Check all four tyres and the spare. Mismatched dates often mean one or two tyres were replaced after damage, which is worth asking about. Spare tyres on older cars are frequently original and well past five years, even though they have never been used.
Signs an old tyre needs replacing now
Age-related failure shows as cracking on the sidewall and between the tread blocks, rubber that feels hard and shiny, and distortion such as bulges or an uneven tread surface. A tyre with these signs should be replaced even if it is younger than five years.
Many tyre manufacturers advise a professional inspection every year once a tyre is five years old, and replacement at ten years at the latest regardless of condition. In the UAE, the practical five-year limit arrives first. Spare tyres follow the same rules, which matters because you rely on them in an emergency.
Fines and insurance consequences
Under UAE federal traffic law, the fine for unfit tyres is AED 500 and 4 black points, and police can also impound a vehicle that is unsafe to drive. Aged, cracked or bald tyres can fall under this category during roadside checks.
After an accident, an insurer or investigator may check tyre condition and age. Expired or badly worn tyres can complicate a claim. Keeping tyres within the five-year window and above the 1.6 mm tread limit protects both your safety and your cover.
