The Four-Digit Code Most Buyers Never Check
A buyer came to us with a straightforward question.
She had just taken delivery of a new family crossover. Everything looked right — the car was pristine, the mileage was low, the paperwork was in order.
But a friend had told her to check the tyres. She didn’t know what to look for, so she booked an inspection.
Our inspector found the DOT codes on all four tyres. Three had been manufactured in week 18 of 2022. One — apparently a replacement — was from 2023.
The car she was driving was a 2025 model.
Her tyres were between two and three years old before she had driven a single kilometre in her own name.
Why Tyre Age Is Separate From Tyre Mileage
Most people think about tyres in terms of tread depth. The deeper the groove, the more life remains.
This is true — but only half the story.
Tyres degrade chemically over time, regardless of how much they’ve been driven. UV exposure, heat, and oxidation break down the rubber’s elasticity. As it hardens, the tyre becomes more prone to cracking, sudden failures, and blowouts.
In the UAE, this happens faster than almost anywhere else. Extreme summer heat, intense UV, and coastal ozone accelerate rubber degradation significantly. Most tyre manufacturers recommend replacement at six years from manufacture — some recommend five years in high-heat climates.
If you’re collecting a new car with tyres already two or three years old, your effective tyre life is significantly shorter than you might assume.
How to Read the DOT Tyre Manufacturing Date
Every tyre carries a DOT code moulded into the sidewall. The last four digits tell you the manufacturing date.
Format: WWYY (Week / Year)
Example: A code ending in 2322 = 23rd week of 2022 (approximately June 2022).
Where to find it: Look on the inner sidewall — the side facing the car’s centre. The code begins with “DOT” and ends with those four digits.
Check all four tyres. And check the spare.
What Tyre Age Is Acceptable at Delivery?
| Tyre Age | Assessment |
|---|---|
| Under 12 months | Excellent. |
| 12–18 months | Normal for vehicles shipped to the UAE. |
| 18–24 months | Acceptable — ask how the car was stored. |
| 24–36 months | Worth negotiating a concession or replacement. |
| Over 36 months | Address this before accepting delivery. |
Why This Happens
Tyres are fitted to vehicles at the factory — sometimes months before the car even leaves production. The vehicle then ships to the UAE (weeks), waits at the port (more weeks), goes through the importer’s PDI process, and eventually reaches the showroom.
For fast-moving models this timeline is compressed. For cars sitting in inventory, the gap between tyre manufacture and your delivery date can be significant.
Many showroom sales staff have never read a DOT code. This is not malice — it’s a gap in the process that informed buyers can close themselves.
What to Do If the Tyres Are Older Than You’d Like
Request replacement tyres. If the tyres are more than two years old, you have a reasonable basis to request replacement as a condition of purchase.
Negotiate a price reduction. If the dealer won’t replace them, the cost of a new set is a legitimate deduction.
Get it in writing. If you accept older tyres, have the tyre age documented in your purchase paperwork — this protects you if tyre-related issues arise later.
Book a tyre inspection. Our tyre check covers tread depth, sidewall condition, flat spotting, and DOT age across all four tyres plus the spare.
The Connection to Other New Car Risks
Older tyres are usually a symptom of a car that’s been sitting longer than the showroom admits. That’s also why the battery and fluids are worth testing on the same visit, and why it’s worth checking if the car had any pre-delivery repairs that weren’t disclosed.
