Tire Production Year Matters More Than Most Drivers Think

Ensure tire safety by checking production dates. Tires may appear fine externally but can be unsafe as they age. The DOT code “3220” indicates production in the 32nd week of 2020. Replace tires every 6-10 years regardless of appearance.

A tire can look perfectly fine on the outside and still be unsafe.

Tires are made of rubber compounds that age over time, even if the tread depth looks good and the tire hasn’t been driven much. Heat, oxygen, and UV exposure slowly break down the rubber, causing it to harden and lose grip.

That’s why the tire production year is critical.

You can find it on the sidewall as part of the DOT code — the last four digits show the week and year the tire was manufactured (for example, 3220 means week 32 of 2020).

Most manufacturers and safety organizations recommend replacing tires after 6 years, and no later than 10 years, regardless of appearance.

An old tire may:

• Have reduced traction, especially in wet or cold conditions

• Be more prone to cracking or sudden failure

• Perform poorly during braking and emergency maneuvers

This tire looks OK, Right?

The tire on the vehicle appears well-maintained with strong treads, indicating good condition for safe driving.

BUT IT IS NOT!

Tire manufactured in 2017 with visible wear, indicating it may be expired and in need of replacement for safety.

In short: good tread does not equal a good tire.Age matters — and ignoring it can compromise safety.
