tire pressure Acura RL 2008 Owner's Guide

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
f or 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 one to two 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
pressures on page .

The following charts show the
recommended cold tire pressures f or
most normal and high-speed driving
conditions.For convenience, the recommended
tire sizes and cold tire pressures are
on a label on the driver’s doorjamb.
For additional technical inf ormation
about your tires, see page .Every time you check inf lation, you
should also examine the tires f or

A tire this worn gives very little
traction on wet roads. You should
replace the tire if you can see three
or more tread wear indicators.
Your tires have wear indicators
molded into the tread. When the
tread wears down, you will see a 1/2
inch (12.7 mm) wide band across the
tread. This shows there is less than
1/16 inch (1.6 mm) of tread lef t on
the tire.The service lif e of your tires is
dependent on many f actors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inf lation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inf lation pressure
maintenance, it is recommended that
you have annual inspections
perf ormed once the tires reach f ive
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.The last four digits of the TIN (tire
identif ication number) are f ound on
the sidewall of the tire and indicate
the date of manufacture (See
on page ).468

In addition to proper inf lation,
correct wheel alignment helps to
decrease tire wear. If you f ind a tire
is worn unevenly, have your dealer
check the wheel alignment.
Have your dealer check the tires if
you f eel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed f rom the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comf ort and tire lif e. For best results,
have the installer perform a dynamic
balance.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.
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.
When the tires are rotated, make
sure the air pressures are checked. 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.

There are no snow tires compatible
with the PAX system, and not all tire
chains are suitable f or use on the
PAX system tires.If you must continue driving with a
f lat tire, f ollow all the procedures
and precautions described on page.
Never use a tire repair agent in a
PAX system tire, and never repair
a PAX system tire by yourself .
Repair or replacement must be
done by an Acura dealer or an
authorized Michelin PAX system
dealer.
Your vehicle is equipped with the
Michelin PAX system which,
together with the tire pressure
monitoring system (TPMS), enables
you to continue driving even if one or
more of your tires loses its pressure.
The tires and wheels on your vehicle
are specially designed f or the PAX
system, and the PAX system is
specif ically designed and f ine-tuned
foryourvehicle.
Because of these reasons, use only
the wheels and tires designated in
this owner’s manual. Never mix PAX
system wheels or tires with
conventional wheels or tires. If you mount snow chains on your
tires, use the chains recommended
by Acura (see page ).
Do not replace the PAX system tires
and wheels with conventional tires
andwheels.Doingsowoulddisable
the PAX system and the tire
pressure monitoring system (TPMS),
and may void your new vehicle
warranty.

Your vehicle is equipped with the
Michelin PAX system. Since each
Michelin PAX system tire has an
inner support ring that allows it to
continue running without air, it may
be dif f icult to immediately judge
f rom its appearance if a tire is
punctured. Your vehicle is also
equipped with a tire pressure
monitoring system (TPMS), and this
system may be your f irst detection of
a f lat tire.If the indicator and the message
come on again, you probably have a
flat tire. In this case, you will see a
‘‘PAX SYSTEM WARNING’’
message on the multi-inf ormation
display.
The TPMS monitors the air pressure
of all f our tires whenever the ignition
switch is in the ON (II) position. It
will immediately sense if a tire starts
to lose its pressure, and give you
warning with the low tire pressure/
TPMS indicator in the instrument
panel and a ‘‘CHECK TIRE
PRESSURE’’ message on the multi-
inf ormation display. If the indicator
and the warning message do not
come on again af ter you inf late the
tire to its correct air pressure (see page ), it was probably a natural
loss of the air pressure and you can
continue driving as bef ore.

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.
After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
Af ter several miles (kilometers)
driving with the spare, this
indicator begins to f lash, then
stays on again. You will also see a
‘‘CHECK TPMS SYSTEM’’
message on the multi-inf ormation
display (see page ). 375
