2012 HONDA ACCORD COUPE tire size

Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
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
In certain unusual conditions when
your vehicle gets stuck in shallow
mud or f resh snow, it may be easier
to free it with the VSA temporarily
switched of f . When the VSA system

Immediately af ter f reeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
This switch is under the driver’s side
vent. To turn the VSA system on and

When VSA is off, the VSA OFF

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.
To saf ely operate your vehicle, your
tires must be the proper type and
size, in good condition with adequate
tread, and correctly inf lated.
The f ollowing pages give more
detailed inf ormation on how to take
care of your tires and what to do
when they need to be replaced.
Overinf lated tires can make your
vehiclerideharshly,aremore
prone to damage f rom road
hazards, and wear unevenly.
Thetirepressuremonitoringsystem
(TPMS) warns you when a tire
pressure is low. See page f or
more inf ormation. 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 1 to 2 psi (10 to
20 kPa, 0.1 to 0.2 kgf /cm ) per
month. Remember to check the
sparetireatthesametime. 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.
Check the air pressures when the
tires are cold. This means the
vehicle has been parked f or at least 3
hours, or driven less than 1 mile (1.6
km). Add or release air, if needed, to
match the recommended cold tire
pressures on the next page.

Using tires that are excessively

If you check air pressures when the
tires are hot (driven f or several
miles/kilometers), you will see
readings 4 to 6 psi (30 to 40 kPa, 0.3

While tubeless tires have some
ability to self -seal if they are

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.
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.
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
youfindeitherof theseconditions.
Cuts, splits, or cracks in the side
of the tire. Replace the tire if you
can see f abric or cord.
Excessive tread wear.
We strongly recommend that you do
not drive faster than the posted
speed limits and conditions allow. If
you ever drive in a sanctioned
competitive event at sustained high
speeds (over 118 mph or 190 km/h),
be sure to adjust the cold tire

not, excessive heat can build up and

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.Replacement wheels are available at
your dealer. 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.
Also be sure you use only TPMS
specif ic wheels. If you do not, the
tire pressure monitoring system will
notworkonthattire.
The ABS and VSA system work by
comparing the speed of each wheel.
When replacing tires, use the same
size originally supplied with the
vehicle. Tire size and construction
can af f ect wheel speed and may
cause the system to activate. Replacing T ires and Wheels

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
vehicle, make sure they are radial
tires of the same size and load range
as the original tires. Mount snow
tires on all f our wheels. The traction

Check with the tire dealer f or
maximum speed recommendations. Mount tire chains on your tires when
required by driving conditions or
local laws. Install them only on the
f ront tires.
Because your vehicle has limited tire
clearance, Honda strongly
recommends using the chains listed
below, made by Security Chain
Company (SCC).

Clean the wheels as you would the
rest of the exterior. Wash them with
thesamesolution,andrinsethem
thoroughly.
When installing chains, 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.
Aluminum alloy wheels have a
protective clear-coat that keeps the
aluminum f rom corroding and
tarnishing. Cleaning the wheels with
harsh chemicals (including some
commercial wheel cleaners) or a stif f
brush can damage the clear-coat. To
clean the wheels, use a mild
detergent and a sof t brush or sponge. Wheels

Using the wrong chains, or not
properly installing chains, can

cause a crash in which you can
be seriously injured or killed.
Follow all instructions in this
owner’s manual regarding the
selection and use of tire chains.
Traction devices that are the wrong
size or improperly installed can
damage your vehicle’s brake lines,

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 tire should be the same
sizeanddesign,mountedonthe
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 air 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
surf aces. Use greater caution
while driving.
Do not mount snow chains on the
compact spare tire.
Do not use your compact spare
tire on another vehicle unless it is
thesamemakeandmodel.
The low tire pressure indicator
comes on and stays on af ter you
replace the flat tire with the
compact spare tire. Af ter several
miles (kilometers) driving with the
compact spare tire, the TPMS
indicator comes on and the low
