2004 Acura RL tire pressure

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.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.
Thecompactsparetirepressureis:
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.
Check the pressure in the tires when
they are cold. This means the vehicle
has been parked f or at least three
hours. If you have to drive the
vehicle bef ore checking the tire
pressure, the tires can still be
considered ‘‘cold’’ if you drive less
than 1 mile (1.6 km). If you check the pressure when the
tires are hot [the vehicle 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.
Add or release air, if needed, to
match the recommended cold tire
pressuresonthispage. For convenience, the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.

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.Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Your car’s tires have wear indicators
molded into the tread. When the
tread wears down to that point, you
will see a 1/2 inch (12.7 mm) wide
band running across the tread. This
shows there is less than 1/16 inch
(1.6 mm) of tread lef t on the tire. A
tire that is this worn gives very little
traction on wet roads. You should
replace the tire if you can see the
tread wear indicator in three or more
places around the tire.
Excessive tread wear. Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord. Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherof theseconditions.

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.It is best to replace all f our tires at
thesametime.If thatisnotpossible
or necessary, then replace the two
f ront tires or the two rear tires as a
pair. Replacing just one tire can
seriously af f ect your car’s handling.
The tires that came with your car
were selected to match the perform-
ance capabilities of the vehicle 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.

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.

This section covers the more-
common problems that motorists
experience with their vehicles. It
gives you inf ormation about how to
safely evaluate the problem and what
to do to correct it. If the problem has
stranded you on the side of the road,
you may be able to get going again.

Taking Care of the Unexpected
T aking Care of t he Unexpect ed307

Follow these precautions whenever
you are using the compact spare tire:Thecompactsparetirehasashorter
tread lif e than a regular tire. Replace
it when you can see the tread wear
indicator bars. The replacement
should be the same size and design
tire, mounted on the same wheel.
Thecompactsparetireisnot
designed to be mounted on a regular
wheel, and the compact wheel is not
designed f or mounting a regular tire.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:
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.
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.
Turn of f the VSA system (see
page ).
