2009 Acura RL tire size

When installing cables, f ollow the
manuf acturer’s instructions, and
mount them as tight as you can.
Make sure they are not contacting
the brake lines or suspension. Drive
slowly with them installed. If you
hear them coming into contact with
the body or chassis, stop and
investigate. Remove them as soon as
you begin driving on cleared roads.

Using the wrong chains, or not
properly installing chains, can
damage the brake lines and
cause a crash in which you can
be seriously injured or killed.
Follow all instructions in this
owner’s manual regarding the
selection and use of tire chains.Traction devices that are the wrong
size or improperly installed can
damage your vehicle’s brake lines,
suspension, body, and wheels. Stop
driving if they are hitting any part of
the vehicle.

Use the compact spare tire as a
temporary replacement only. Get
your regular tire repaired or replaced,
and put it back on your vehicle as
soon as you can.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:Replace the tire when you can see
the tread wear indicator bars. The
replacement should be the same size
and design tire, mounted on the
samewheel.Thesparetireisnot
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surf aces. Use greater caution
while driving.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ). 433

The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
Load index (a numerical code
associated with the maximum
load the tire can carry).
Speed symbol (an
alphabetical code indicating
the maximum speed rating).
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. Following 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. This indicates that the
tire meets all
requirements of the U.S.
Department of
Transportation.
Manuf acturer’s
identification mark.

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 inflate 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.
Underinf 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.
