wheel size Acura TL 2004 Owner's Manual

If the indicator does not come on
when the ignition switch is turned to
ON(II),theremaybeaproblem
with the VSA system. Have an Acura
dealer inspect your vehicle as soon
as possible.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.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.
Pressing the switch again turns the
system back on.VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are 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.

Tires: See page f or DOT tire quality
grading inf ormation, and page
f or tire size inf ormation.
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 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.
If your vehicle is equipped with
summer tires, be aware that these
tires are not designed f or winter
driving conditions. For more
inf ormation, consult your Acura
dealer.
If you ever replace a wheel, make
sure that the wheel’s specif ications
match those of the original wheels. 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. 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 side wall).
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
anti-lock brake and the vehicle
stability assist systems to work
inconsistently. 258

235/45R17 93W 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.

If you mount snow tires on your
Acura, make sure they are radial
tires of the same size and load range
as original tires. Mount snow tires on
all f our wheels. The traction
provided by snow tires on dry roads
maybelowerthanyouroriginaltires.
Check with the tire dealer f or
maximum speed recommendations.
Because your Acura has limited tire
clearance, mount only SAE Class ‘‘S’’
cable-type traction devices, with
rubber chain tensioners on the f ront
tires. Use traction devices only when
required by driving conditions or
local laws. Make sure they are the
correct size f or your tires. Metal link-
type ‘‘chains’’ should not be used.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.

NOTICE:
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:Follow these precautions:
Never exceed 50 mph (80 km/h).
This tire gives a harsher ride and
less traction on some road sur-
f aces. Use greater caution while
driving.
Do not mount snow chains on it.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
Turn of f the VSA system (see
page ).
Driving with the compact spare
tiremayactivatetheVSAsystem. 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
same wheel. The spare tire is not
designed to be mounted on a regular
wheel, and the spare wheel is not
designed f or mounting a regular tire.
On models with manual
transmission, do not drive f or a
long period with the compact
spare tire mounted on a f ront
wheel; it will damage the limited
slip dif f erential. 191

Warning: The temperature grade f or
this tire is established f or a tire that
is properly inf lated and not over-
loaded. Excessive speed, underinf la-
tion, or excessive loading, either separately or in combination, can
cause heat buildup and possible tire
f ailure.
Date of manuf acture. Tire type code. Manuf acturer’s
identification mark. This indicates that the tire
meets all requirements of
the U.S. Department of
Transportation.
Tire Identif ication Number (TIN) is
a group of numbers and letters that
look like the f ollowing example TIN.
Speed symbol (an
alphabetical code indicating
the maximum speed rating). Load index (a numerical code
associated with the maximum
load the tire can carry). Rim diameter in inches. Tire construction code (R
indicates radial).
Whenever tires are replaced, they
should be replaced with tires of the
same size. Following is an example
of tire size with an explanation of
what each component means. Aspect ratio (the tire’s section
height as a percentage of its
width). Tire width in millimeters. Vehicletype(Pindicates
passenger vehicle).
The tires that came on your vehicle
have a number of markings. Those
you should be aware of are described
below.
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled
conditions on a specif ied indoor
laboratory test wheel. Sustained high
temperature can cause the material
of the tire to degenerate and reduce
tire life, and excessive temperature
can lead to sudden tire f ailure. The
grade C corresponds to a level of
perf ormance, which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Saf ety
Standard No. 109 and No. 139.
Grades B and A represent higher
levels of perf ormance on the
laboratory test wheel than the
minimum required by law.
