2006 Acura RL tire size

When the CMBS is on, the radar
sensor constantly scans f or vehicles
ahead of you. This means that
driving on a road with a f ew or no
vehicles could cause a CHECK
CMBS RADAR SENSOR message to
appear on the multi-inf ormation
display. This is normal and not a
cause f or concern.The radar sensor may not always
scan as intended. Here are two
examples:
Thetiresarenotcorrectly
maintained. Always make sure the
tire pressures are correct (see
page ), and that the tires are
the correct size and in good
condition (see Tires on page ). Your vehicle is tilted because of a
heavy load in the rear or from
modif ications to the suspension.
Do not overload your vehicle (see
Carrying Cargo on page ), and
do not make any modif ications to
the suspension (see Accessories
and Modif ications on page ). 305

The CMBS will automatically
recover when these conditions are

Any of the conditions below can
cause the CMBS to shut of f . When
the system shuts off, the CMBS
indicator in the instrument panel
comes on, and a CHECK CMBS

multi-inf ormation display f or about 5
seconds.
This indicator comes on f or several

Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
Deactivate the VSA system if you
need to drive with the compact spare
tire installed (see page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
This switch is at the right side of the
lef t vent. Press it to turn VSA on and
off.
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
When the VSA system indicator
comes on, you will also see a
‘‘CHECK VSA SYSTEM’’ message
on the multi-information display.
Without VSA, your vehicle still has
normal braking and cornering ability,
but it does not have VSA traction and
stability enhancement.
If the low tire pressure indicator
comes on (see page ), or the
multi-inf ormation display shows a
‘‘CHECK TPMS SYSTEM’’ message
(see page ), the VSA system
automatically turns on even when
the VSA system is turned of f with
the VSA OFF switch. In this case,
you cannot turn the VSA system of f
by pressing the VSA OFF switch
again.

To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.Keeping the tires properly inf lated
provides the best combination of
handling, tread lif e, and riding
comf ort.
Underinf lated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,are
more prone to damage f rom road
hazards, and wear unevenly.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours, or driven less than 1 mile (1.6
km). Use a gauge to measure the air
pressure in each tire at least once a
month. Even tires that are in good
condition may lose one to two psi (10
to 20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime. We recommend that you visually
check your tires every day. If you
think a tire might be low, check it
immediately with a tire gauge.
Thetirepressuremonitoringsystem
(TPMS)willwarnyouwhenatire
pressure is low. See page f or
inf ormation on the TPMS. Add or release air, if needed, to
match the recommended cold tire
pressures on page .384

Using tires that are excessively

cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this

Excessive tread wear. Cuts, splits, or cracks in the side

Every time you check inf lation, you
should also examine the tires for
damage, f oreign objects, and wear.
Youshouldlookfor: For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb.
For additional technical information
about your tires, see page .
If you check the pressure when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to
0.4 kgf /cm ) higher than the cold
reading. This is normal; do not
release air to match the cold
pressure. The tires will be
underinf lated.
Youshouldgetyourowntire
pressure gauge and use it whenever
you check your tire pressures. This
will make it easier f or you to tell if a
pressure loss is due to a tire problem
and not due to a variation between
gauges.
While tubeless tires have some
ability to self -seal if they are
punctured, you should look closely
for punctures if a tire starts losing
pressure. 427

It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, replace the two f ront
tires or two rear tires as a pair.
Replacing just one tire can seriously
af f ect your vehicle’s handling.Wheels:
Replace your tires with radial tires of
the same size, load range, speed
rating, and maximum cold tire
pressure rating (as shown on the
tire’s sidewall).
Mixing radial and bias-ply tires on
your vehicle can reduce braking
ability, traction, and steering
accuracy. Using tires of a dif f erent
size or construction can cause the
ABS and vehicle stability assist
system (VSA) to work inconsistently. If you ever need to replace a wheel,
make sure the wheel’s specif ications
match those of the original wheel
that came on your vehicle.
Replacement wheels are available at
your Acura dealer.

Installing improper tires on your
vehicle can affect handling and
stability. This can cause a crash
in which you can be seriously
hurt or killed.
Always use the size and type of
tires recommended in this
owner’s manual.

´
Tires marked ‘‘M S’’ or ‘‘All
Season’’ on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.
For the best perf ormance in snowy
or icy conditions, you should install
snow tires or tire chains. They may
be required by local laws under
certain conditions. Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
f ront tires.
If you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as original tires. Mount snow tires on
all f our wheels. The traction
provided by snow tires on dry roads
maybelowerthanyouroriginaltires.
Check with the tire dealer f or
maximum speed recommendations. Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chain listed
below, made by Security Chain
Company (SCC).
Tire chains cannot be used with a
flat front tire. If a front tire goes flat
when a tire chain is installed on it,
remove the chain, and f ollow the
precautions described under
Michelin PAX System (see page
).

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.Your vehicle is not designed f or

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.
