The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
The tire identif ication number (TIN)
is a group of numbers and letters
that look like the f ollowing example.
TIN is located on the sidewall of the
tire.
Whenever tires are replaced, they
should be replaced with tires of the
same size. Below is an example of
tire size with an explanation of what
each component means.
Vehicletype(Pindicates
passenger vehicle).
Tire width in millimeters.
Aspect ratio (the tire’s section
height as a percentage of its
width).
Tire construction code (R
indicates radial).
Rim diameter in inches.
Load index (a numerical code
associated with the maximum
load the tire can carry).
Speed symbol (an
alphabetical code indicating
the maximum speed rating). This indicates that the
tire meets all
requirements of the U.S.
Department of
Transportation.
Manuf acturer’s
identification mark.
Tire type code.
Date of manufacture.

CONT INUED
As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
signif icantly under-inf lated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure.
Each tire, including the spare (if
provided), should be checked
monthly when cold and inf lated to
the inf lation pressure recommended
by the vehicle manuf acturer on the
vehicle placard or tire inf lation
pressure label.
(If your vehicle has tires of a
dif f erent size than the size indicated
on the vehicle placard or tire
inf lation pressure label, you should
determine the proper tire inf lation
pressure f or those tires.)
Max Press The maximum air

Max Load The maximum load the
tire can carry at maximum air
pressure.
