tires HONDA S2000 2004 2.G User Guide

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 affect handling and fuel
economy, and are more likely to
fail from being overheated.
Overinf lated tires can make your
vehicleridemoreharshly,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. Thecompactsparetirepressureis:
For convenience, the recommended
tire sizes and cold air pressures are
on a label on the driver’s doorjamb.
For additional technical inf ormation,
see page .Tire pressure f or high speed driving
is the same as f or normal driving.
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
thesametime.
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.

245/40R17 91W 32 psi (220 kPa , 2.2 kgf/cm

If you check the pressure when the
tires are hot (driven f or several
miles), 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 release air to match
the cold pressure.
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.
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.Every time you check inf lation, you
should also examine the tires f or
damage, f oreign objects, and wear.
Youshouldlookfor:
Bumps or bulges in the tread or
side of the tire. Replace the tire if
youfindeitherortheseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.
Excessive tread wear. Your vehicle’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.

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.You should not rotate your Honda’s
tires. The f ront and rear tires are
dif f erent sizes, so they cannot be
rotated f ront-to-rear. The original-
equipment tires on your Honda have
a unidirectional tread pattern, so
they cannot be rotated side-to-side.
The tires that came on your vehicle
were designed and constructed to
provide superior grip during
acceleration, braking, and cornering.
As a trade-of f , they will wear more
rapidly than tires used on ordinary
passenger vehicles. Because of the
vehicle’s weight distribution, and the
f act that they are the driving wheels,
you may expect the rear tires to wear
more rapidly than the f ront tires.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 to work inconsistently.
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.
If you ever replace a wheel, make
sure that the wheel’s specif ications
match those of the original wheels.

See page f or DOT tire quality
grading inf ormation, and page
f or tire size explanation. 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 you mount snow tires on your
Honda, 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

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.

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. Because your Honda has limited tire
clearance, mount only SAE Class ‘‘S’’
cable-type traction devices, with
rubber chain tensioners on the rear
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.

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.

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.Fill the f uel tank.
Change the engine oil and f ilter.
Wash and dry the exterior
completely.
Cleantheinterior.Makesurethe
carpeting, floor mats, etc., are
completely dry.
Raise the convertible top cover.
Leave the parking brake off. Put
the transmission in Reverse. 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).
Disconnect the battery.
Cover the vehicle with a
‘‘breathable’’ cover, one made
f rom a porous material such as
cotton. Non-porous materials, such
as plastic sheeting, trap moisture,
which can damage the paint.
If possible, periodically run the
engine until it reaches f ull
operating temperature (the
cooling f ans cycle on and of f
twice). Pref erably, do this once a
month.
If you store your vehicle f or 1 year or
longer, have your Honda dealer
perf orm the inspections called f or in
the 2 years/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.
Support the f ront wiper blade
arms with a f olded towel or rag so
they do not touch the windshield.
To minimize sticking, apply a
silicone spray lubricant to all door
and trunk seals. Also, apply a
vehiclebodywaxtothepainted
surfaces that mate with the door
and trunk seals.

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.Follow these precautions:
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.
Check the inf lation pressure of the
compact spare tire every time you
check the other tires. It should be
inf lated to:
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.

µ The tow
truck uses two pivoting arms that go
under the tires (f ront or rear) and
lif ts them of f the ground. The other
two tires remain on the ground.
Because the S2000 sits so low, the
body could come in contact with the
ground and be damaged. The tow
truck uses metal cables with hooks
on the ends. These hooks go around
parts of the f rame or suspension and
the cables lif t that end of the vehicle
of f the ground. Your vehicle’s sus-
pension and body can be seriously
damaged.
If your vehicle needs to be towed,
call a prof essional towing service or
organization. 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.
When you contact the towing agency,
inf orm them that you have an S2000
and that a f lat-bed is required.
