wheel size Acura RL 2007 Owner's Manual

Driving with varying tire or wheel
sizes may cause the VSA to
malfunction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system
is of f , the traction control system is
alsooff.Youshouldonlyattemptto
f ree your vehicle with the VSA of f if
you are not able to f ree it when the
VSA is on.
Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
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.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.

Keeping the tires properly inflated
provides the best combination of
handling, tread life, and riding
comfort.
Underinflated tires wear unevenly,
adversely affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinflated tires can make your
vehicleridemoreharshly,are
more prone to damage from road
ha zards, and wear unevenly.
Thetirepressuremonitoringsystem
(TPMS)will warnyouwhenatire
pressu re is low. See page for
inf ormation on the TPMS.
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. 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.
Clean the wheels as you would the
rest of the exterior. Wash them with
thesamesolution,andrinsethem
thoroughly.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum f rom corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stif f
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a sof t brush or sponge.

It is best to replace all four tires at
thesametime.Ifthatisnotpossible
or necessary, replace the two front
tires or two rear tires as a pair.
Replacing just one tire can seriously
affect 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 different
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 specifications
match those of the original wheel
that came on your vehicle.
Replacement wheels are available at
your Acura dealer. Tires:

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 performance 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
front tires.
If
you mount snow tires on your
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all four wheels. The traction
provided by snow tires on dry roads
maybelowerthanyouroriginaltires.
Check with the tire dealer for
maximum speed recommendations. Because
your vehicle has limited tire
cl earance, 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
Michelin PAX system wheels or tires.
Use only the wheels and tires
designated in this owner’s manual.
Never mix conventional wheels or
tires with PAX system wheels or
tires.

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.
