Tyre age is one part of condition. The common four-digit manufacture code identifies production week and year, but tread depth alone does not prove that an older tyre is serviceable.
What to check
A code such as 2424 means week 24 of 2024.
Look for cracking, deformation, hardening and recurring pressure loss as tyres age.
Specific legal age restrictions apply to certain heavy goods and passenger vehicles; ordinary car tyres still need condition-based assessment.
How to use the date code
The common four-digit code gives week and year of manufacture; it does not state an expiry date. Use it alongside physical condition, storage history, vehicle use and manufacturer guidance. A little-used spare can age even when tread remains deep.
Older tyres deserve closer inspection
Look for cracking, hardening, distortion, vibration and recurring pressure loss. If the code is unclear or the tyre has an unknown history, a professional inspection is more useful than guessing from appearance alone.
TyreDeck can help you spot warning signs, but it cannot inspect the tyre internally, measure damage, verify pressure calibration or certify that a tyre is safe to drive on. If you are unsure, avoid unnecessary driving and arrange a competent physical inspection.
What to do next
A garage or competent tyre professional can inspect pressure loss, ageing, fitment or another condition that cannot be confirmed online.
