Maintenance Fundamentals
Tire Service Life
The service life of your tires is dependent on
many factors, including, but not limited to,
riding habits, road conditions, vehicle
loading, tire air pressure, maintenance
history, speed, and environmental
conditions (even when the tires are not in
use).
In addition to your regular inspections and
maintenance, it is recommended that you
have annual inspections performed once
the tires reach 5 years old. It is also
recommended that all tires be removed
from service after 10 years from the date of
manufacture, regardless of their condition
or state of wear.
The last four digits of the TIN (tire
identification number) indicate the date of
manufacture.
