tire size Acura TSX 2004 Owner's Manual

VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the car.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
car. Exercise the same caution
during winter driving as you would if
your car was not equipped with VSA.276

Use a gauge to measure the air
pressure 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 spare tire at
thesametimeyoucheckallthe
other tires.
Check the pressure in the tires when
they are cold. This means the car
has been parked f or at least three
hours. If you have to drive the car
bef ore checking the tire pressure,
the tires can still be considered
‘‘cold’’ if you drive less than 1 mile
(1.6 km).
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 af f ect handling
and f uel economy, and are more
likely to f ail f rom being overheated.
Overinf lated tires can make your car
ride more harshly, are more prone to
damage f rom road hazards, and wear
unevenly.
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.
To saf ely operate your car, your tires
must be the proper type and size, in
good condition with adequate tread,
and correctly inf lated. The f ollowing
pages give more detailed inf ormation
on how and when to check air
pressure, how to inspect your tires
for damage and wear, and what to do
when your tires need to be replaced.
Add or release air, if needed, to
match the recommended cold tire
pressures on page .274

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 chart shows the
recommended cold tire pressures f or
most normal driving conditions and
speeds. Tire pressures f or high
speed driving are the same as f or
normal driving.
If you check the pressure when the
tires are hot [the car has been driven
several miles (kilometers)], you will
see readings 4 to 6 psi (30 to 40 kPa,
0.3 to 0.4 kgf /cm ) higher than the
cold reading. This is normal. Do not
let air out to match the specif ied cold
pressure. The tire 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.
Thecompactsparetirepressureis:For convenience, the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.
For additional technical information
about your tires, see page .
Tubeless tires have some ability to
self -seal if they are punctured.
However, because leakage is of ten
very slow, you should look closely
for punctures if a tire starts losing
pressure.

When shopping f or replacement
tires, you may find that some tires
are ‘‘directional.’’ This means they
are designed to rotate only in one
direction. If you use directional tires,they should be rotated only front-to-
back.
Make sure the installer balances the
wheels when you have new tires
installed. This increases riding
comf ort and tire lif e. Your car’s
original tires were dynamic or ‘‘spin’’
balanced at the f actory. For best
results, have the installer perf orm a
dynamic balance. The tires that came with your car
were selected to match the perform-
ance capabilities of the car while
providing the best combination of
handling, ride comf ort, and long lif e.
Youshouldreplacethemwithradial
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 car can reduce
its braking ability, traction, and
steering accuracy.
To help increase tire lif e and
distribute wear more evenly, you
should have the tires rotated every
10,000 miles (16,000 km). Move the
tires to the positions shown in the
chart each time they are rotated. Tire Rotation

Installing improper tires on your
car 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 that are marked ‘‘M S’’ or
‘‘All Season’’ on the sidewall have an
all-weather tread design. They
should be suitable f or most winter
driving conditions. Tires without
these markings are designed f or
optimum traction in dry conditions.
They may not provide adequate
perf ormance in winter driving.
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 snow chains on your tires
when required by driving conditions
or local laws. Install them only on the
f ront tires.
Because your car has limited tire
clearance, Acura strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).
If you mount snow tires on your
Acura, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tiresonallfourwheelstobalance
your car’s handling in all weather
conditions. Keep in mind the traction
provided by snow tires on dry roads
may not be as high as your car’s
original equipment tires. You should
drive cautiously even when the roads
are clear. Check with the tire dealer
f or maximum speed recommen-
dations.

should be the same size and design

Thecompactsparetireisnot

Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to: Your car has a compact spare tire
that takes up less space. Use this
sparetireasatemporaryreplace-
ment only. Get your regular tire
repaired or replaced and put it back
on your car as soon as you can.
Follow these precautions whenever
you are using the compact spare tire:
Do not exceed 50 mph (80 km/h)
under any circumstances. This tire gives a harsher ride and
less traction on some road sur-
f aces than the regular tire. Use
greater caution while driving on
this tire.
Do not mount snow chains on the
compact spare.
The wheel of the compact spare
tire is designed especially to f it
your car. Do not use your spare
tire on another car unless it is the
same make and model.
