How Old Is Too Old for Motorcycle Tires?

Michelin recommends replacing motorcycle tires when 10 years have passed since the date in the DOT code, regardless of the tread left.

Michelin also recommends a professional inspection every year once the tires have been in use for 5 years.

Michelin says rubber degrades from ozone, heat and ultraviolet rays, even on a motorcycle that is used rarely.

RevZilla notes that many manufacturers traditionally recommended replacement after 5 years, and argues that age alone does not automatically make a tire unsafe. That is RevZilla's opinion, not a rule.

Why motorcycle tires age regardless of mileage

According to Michelin, the rubber of a motorcycle tire degrades from ozone, heat and ultraviolet rays, even if the motorcycle is used rarely.

This is why Michelin counts the age of the tire from the DOT code and not only the kilometers or the tread.

Michelin also recommends replacing a tire when the tread reaches the wear indicator, which is 2/32 of an inch (1.6 mm).

RevZilla's article includes tests on old tires and takes a different view from the traditional 5-year advice. It is one publication's opinion.

Michelin's recommendation is still to replace at 10 years from the DOT date, regardless of the tread left.

How to check motorcycle tire age

According to Michelin, the last 4 digits of the DOT code show the week and the year of manufacture.

Step-by-step example: Reading DOT code 1922

  1. Find the DOT code: Look for the DOT code on the tire.
  2. Take the last 4 digits: These show the week and the year.
  3. Read the week: In Michelin's example code 1922, the first two digits (19) are the week, so week 19.
  4. Read the year: In the same example, the last two digits (22) are the year, so 2022.
  5. Count the age: Count the years from week 19 of 2022 to today and compare the result with the 10-year recommendation above.

Frequently asked questions

Should I replace motorcycle tires at 10 years if the tread is still good?

Michelin recommends replacing motorcycle tires 10 years after the date in the DOT code, regardless of the tread left.

Michelin says ozone, heat and ultraviolet rays degrade the rubber even when the motorcycle is used rarely.

Why do many riders talk about replacing motorcycle tires at 5 years?

RevZilla notes that many manufacturers traditionally recommended replacement after 5 years.

Michelin recommends a professional inspection every year once the tires have been in use for 5 years.

Do car tire age guidelines apply to motorcycles?

NHTSA's tire page says some manufacturers recommend replacing tires 6 to 10 years after manufacture.

That page is about passenger vehicles, not motorcycles, so it is not a motorcycle rule.
