Acura 2009 RL - Manual (Page 482)

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