The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below. 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. Speed symbol (an
alphabetical code indicating
the maximum speed rating). Load index (a numerical code
associated with the maximum
load the tire can carry).

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.)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 inf late them to
the proper pressure.Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect 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-inf lation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
