tire size Acura TSX 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 ).
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 under the lef t vent.
Press it to turn the vehicle stability
assist system on and of f .
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.
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

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.

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.
To
safely operate your vehicle, your
ti res must be the proper type and
size, in good condition with adequate
tread, and correctly inflated.
The following pages give more
detailed information on how to take
care of your tires and what to do
when they need to be replaced.

inf ormation on the TPMS.
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.

Using tires that are excessively
worn or improperly inflated can
cause a crash in which you can
be seriously hurt or killed.
Follow all instructions in this
owner’s manual regarding tire
inflation and maintenance.

The following charts show the
recommended cold tire pressures for
most normal and high-speed driving
conditions.
For additional information about
your tires, see page .
For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb. Thecompactsparetirepressureis:
If you check air pressures when the
tires are hot [driven f or several miles
(kilometers)], you will see readings 4
to6psi(30to40kPa,0.3to0.4
kgf /cm ) higher than the cold
readings. This is normal. Do not let
air out to match the recommended
cold air pressure. The tire will be
underinf lated.
Youshoulduseyourowntire
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.
Even though your vehicle is
equipped with TPMS, 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.
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 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime.
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). Add or release air, if needed, to
match the recommended cold tire
pressure.

To help increase tire lif e and
distribute wear more evenly, rotate
the tires according to the
maintenance messages displayed on
the multi-information display. Move
the tires to the positions shown in
the illustration each time they are
rotated. If you purchase directional
tires, rotate only front-to-back.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.
TheABSworksbycomparingthe
speed of the wheels. When replacing
tires, use the same size originally
supplied with the vehicle. Tire size
and construction can affect wheel
speed and may cause the system to
activate.
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.

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

Check with the tire dealer for
maximum speed recommendations.
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.
Tires
marked ‘‘M S’’ or ‘‘All
Season’’ on the sidewall have an all-
weather tread design suitable for
most winter driving conditions.

If
you ever replace a wheel, make
sure that the wheel’s specifications

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.

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.
Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
f ront tires.
Because your vehicle has limited tire
clearance, Acura strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).

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.

Check the inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road
surfaces. Use greater caution
while driving. Do
not mount snow chains on the
compact spare tire.
Do not use the compact spare tire
if you are towing a trailer.
Replace the tire when you can see
the tread wear indica tor 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 for mounting a regular tire.
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.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
On models with manual
tran smission, do not drive for a
long period with the compact
spare tire mounted on a f ront
wheel; it will damage the limited
slip dif f erential. Turn of f the VSA system (see
page ). Driving with the
compact spare tire may activate
the VSA system. 263

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.)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.
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.
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.
