The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
Tire SizeWhenever tires are replaced, they
should be replaced with tires of the
same size. The following is an
example of tire size with an
explanation of what each component
means.P255/50R19 103H
P －Vehicle type (P indicates
passenger vehicle).
255 －Tire width in millimeters.
50 －Aspect ratio (the tire's
section height as a
percentage of its width).
R －Tire construction code (R
indicates radial).
19 －Rim diameter in inches. 103
－Load index (a numerical code
associated with the
maximum load the tire can
carry).
H －Speed symbol (an
alphabetical code indicating
the maximum speed rating).
Tire Identification Number (TIN)The tire identification number (TIN)
is a group of numbers and letters that
look like the following example. TIN
is located on the sidewall of the tire.
DOT B97R FW6X 2202
DOT －This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.
B97R －Manufacturer's
identification mark.

Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label.
(If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.)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
significantly under-inflated.
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.Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
