2003 Acura MDX tires

´
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.

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
work inconsistently.

If you ever need to replace a wheel,
make sure the wheel’s specif ications
match those of the original wheel
that came on your vehicle. Re-
placement wheels are available at
your Acura dealer. 392

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

your vehicle’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 vehicle’s
original-equipment tires. You should
drive cautiously even when the roads
areclear.Checkwiththetiredealer
f or maximum speed recommen-
dations.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.
When installing cables, f ollow the
manuf acturer’s instructions and
mount them as tightly as you can.
Drive slowly with them installed. If
youhearthemcomingincontact
with the body or chassis, stop and
investigate. Make sure the cables are
installed tightly, and that they are
not contacting the brake lines or
suspension. Remove them as soon asyou begin driving on cleared roads.
Metal link-type ‘‘chains’’ should not
be used. No matter how tight they
seem to be installed, they can come
into contact with the body and
suspension, causing serious damage.

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.

If you need to park your vehicle f or
an extended period (more than one
month), there are several things you
should do to prepare it f or storage.
Proper preparation helps prevent
deterioration and makes it easier to
get your vehicle back on the road. If
possible, store your vehicle indoors.Block the rear wheels.
If the vehicle is to be stored f or a
longer period, it should be
supported on jackstands so the
tires are of f the ground.
Leave one window open slightly (if
the vehicle is being stored
indoors).
Fill the f uel tank.
Change the engine oil and f ilter
(see page ).
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc. are
completely dry.
Leave the parking brake off. Put
the transmission in Park. Support the f ront and rear wiper
blade arms with a f olded towel or
ragsotheydonottouchthe
windshield. Disconnect the battery.
To minimize sticking, apply a
silicone spray lubricant to all door
and tailgate seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and tailgate seals.Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Nonporous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, run the engine f or a
while periodically (pref erably once
amonth).
If you store your vehicle f or 12
months or longer, have your Acura
dealer perf orm the inspections called
f or in the 24 months/30,000 miles
(48,000 km) maintenance schedule
(Normal Conditions) as soon as you
take it out of storage (see page ).
The replacements called f or in the
maintenance schedule are not
needed unless the vehicle has
actually reached that time or mileage.

Your vehicle 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 vehicle as soon as you can.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:
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 exceed 50 mph (80 km/h)
under any circumstances.
Follow these precautions whenever
you are using the compact spare tire: Do not mount snow chains on the
compact spare.
Do not use the compact spare tire
if you are towing a trailer.
The wheel of the compact spare
tire is designed especially to f it
your vehicle. Do not use your

If your vehicle needs to be towed,
call a prof essional towing service or,
if youbelongtoone,anorganization
that provides roadside assistance.
Never tow your vehicle behind
another vehicle with just a rope or
chain. It is very dangerous.
There are three popular types of
prof essional towing equipment.
The operator
loads your vehicle on the back of a
truck. Any other
method of towing will damage the
drive system. When you contact the
towing agency, inf orm them that a
f lat-bed is required. The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and lif t
them of f the ground. The other two
tires remain on the ground. Refer to
on page
for non-emergency towing
inf ormation.
The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
cables lif t that end of the vehicle of f
the ground. Your vehicle’s
suspension and body can be
seriously damaged. 283Flat -bed Equipment

The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specif ied government
test course. For example, a tire
graded 150 would wear one and one-
half (1 1/2) times as well on the
government course as a tire graded
100. The relative perf ormance of
tires depends upon the actual condi-
tions of their use, however, and may
depart signif icantly f rom the norm
due to variations in driving habits,
service practices and dif f erences in
road characteristics and climate. The traction grades, f rom highest to
lowest, are AA, A, B, and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured
under controlled conditions on
specif ied government test surf aces
of asphalt and concrete. A tire
marked C may have poor traction
perf ormance.
The tires on your vehicle meet all
U.S. Federal Saf ety Requirements.
All tires are also graded f or
treadwear, traction, and temperature
perf ormance according to
Department of Transportation
(DOT) standards. The f ollowing
explains these gradings.
Quality grades can be f ound where
applicable on the tire sidewall
between the tread shoulder and the
maximum section width. For
example:
All passenger car tires must conf orm
to Federal Saf ety Requirements in
addition to these grades. Warning: The traction grade
assignedtothistireisbasedon
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning, or peak
traction characteristics.
