Yes—a tyre manufactured two years ago can still be a sensible purchase. The date stamped on the sidewall tells you when the tyre was made, but it does not by itself tell you whether the tyre is unsafe or unsuitable. What matters is whether the tyre is unused, has been stored correctly, is free from damage or perishing, and is the correct size and rating for your vehicle.
This guide explains how Auckland drivers can check tyre age, what New Zealand WoF inspections look for, and what to ask before buying.
How to read a tyre manufacturing date
Look for the four-digit date code at the end of the tyre identification marking on the sidewall. The first two digits are the week and the last two digits are the year.
- 2424 means the tyre was manufactured in week 24 of 2024.
- 3825 means the tyre was manufactured in week 38 of 2025.
The date code is useful, but it should be considered together with the tyre’s condition, storage history, specifications and intended use. If you also need help understanding numbers such as 265/65R17, read our guide to reading tyre sizes.
Does a two-year-old tyre count as old?
A tyre can be unused even when it was not manufactured this year. A properly stored two-year-old tyre may still have substantial usable service life. Rubber ageing is affected by heat, sunlight, weather, moisture, storage conditions, inflation, vehicle load and how the tyre is used—not simply the calendar date.
For stored tyres, Michelin recommends a clean, ventilated, temperate location protected from weather and direct sunlight. This is why the condition and storage history of an unused tyre matter as much as the date code.
Will a two-year-old tyre pass a New Zealand WoF?
The current NZ Transport Agency WoF inspection criteria do not list “two years old” as an automatic rejection reason. Inspectors assess whether the tyre is compatible with the vehicle, safely fitted and in acceptable condition.
For most standard road tyres, the tread must be at least 1.5 mm around the whole circumference within the principal grooves containing tread-depth indicators. A tyre can also be rejected for safety-related damage such as a bulge, exposed cords, serious cuts, embedded sharp objects or significant perishing caused by age, moisture or exposure.
That means a newer tyre can still be unsuitable if it is damaged or incorrectly specified, while an unused two-year-old tyre may be acceptable if it has been stored properly and passes a professional inspection.
What should you check before buying?
- Confirm the complete tyre size. Match the width, profile, rim diameter and construction shown by the vehicle manufacturer.
- Check load and speed ratings. The tyre must be suitable for the vehicle and its expected load.
- Read the date code. Ask the seller to show you the four-digit manufacturing code if it is not visible.
- Inspect the rubber. Look for cracking, perishing, bulges, cuts, distortion or damaged beads.
- Ask how it was stored. Cool, dry, sheltered storage away from sunlight and extreme temperatures is preferable.
- Confirm the warranty and invoice. Warranty terms vary by tyre brand, so keep proof of purchase and check when coverage begins.
- Use professional fitting and balancing. Correct installation helps avoid vibration, bead damage and uneven wear.
When does tyre age become more important?
Tyre makers can have different recommendations. Michelin, for example, advises professional annual checks after five years of use and precautionary replacement once a tyre reaches ten years from its manufacturing date, even if tread remains. Always follow the advice for the specific tyre brand and your vehicle manufacturer.
Age deserves extra attention on vehicles that travel low kilometres, spend long periods outdoors, carry heavy loads, tow, or use a spare tyre that is rarely inspected.
Check alignment when replacing tyres
Uneven shoulder wear, a vehicle pulling to one side or an off-centre steering wheel can point to an alignment problem. Correcting it can help protect your replacement tyres. At Zoom Tyres, wheel alignment is approximately NZ$50–$100, depending on the vehicle and the adjustments required. See our Auckland wheel-alignment price guide.
Frequently asked questions
Is a two-year-old tyre still new?
It may still be unused, but “unused” does not guarantee condition. Check the manufacturing date, storage history, rubber condition, specifications and warranty before purchasing.
Is the four-digit code an expiry date?
No. It records the week and year of manufacture. It helps with age checks but does not replace a physical inspection.
Can a tyre fail a WoF because it is old?
Age alone is not listed as a simple cut-off in the current NZTA criteria. However, significant perishing caused by age, moisture or exposure is a rejection reason, as are insufficient tread and serious damage.
Is 1.5 mm enough for every tyre?
The 1.5 mm rule applies to most standard road tyres. NZTA specifies a 4 mm minimum for winter tyres, so the tyre type matters.
Should I replace all four tyres together?
It depends on wear, vehicle type and drivetrain. Tyres on the same axle must be compatible, and some AWD or 4WD vehicles may require closely matched rolling circumference. Ask us to inspect the vehicle before mixing new and worn tyres.
