Wear Indicators
The groove where the wear indicator is
located is about 1/16 inch (about 1.6 mm)
shallower than elsewhere on the tire. If the
tread has worn so that the indicator is
exposed, replace the tire.
Worn out tires have poor traction on wet
roads.
Tire Service Life
The life of your tires is dependent on many factors, including driving habits, road
conditions, vehicle loading, inflation pre ssure, maintenance history, speed, and
environmental conditions (even when the tires are not in use).
In addition to regular inspections and inflation pressure maintenance, it is
recommended that you have annual inspections performed once the tires reach five
years old. All tires should be removed fro m service after 10 years from the date of
manufacture, regardless of their condition or state of wear.
1 Checking Tires
High speed driving
We recommend that you do not drive on public roads
faster than the posted sp eed limits and conditions
allow. If you intend to driv e at sustained high speeds
(over 168 mph or 270 km/h), such as at a track or
other closed course venue , adjust the cold tire
pressures as shown below to avoid excessive heat
build up and sudden tire failure.

Maintenance
Tire and Wheel Replacement
Replace your tires with radials of the same size, load range, speed rating, and
maximum cold tire pressure rating (as shown on the tire’s sidewall). Using tires of a
different size or construction can cause ce rtain vehicle systems such as the ABS and
Vehicle Stability Assist
TM (VSA ®) system to work incorrectly.
It is best to replace all four tires at the same time.
If you replace a wheel, only use TPMS spec ified wheels approved for your vehicle.
Make sure that the wheel’s specifications match those of the original wheels.

3WARNING
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.

Handling the Unexpected
If a Tire Goes Flat
Temporarily Repairing a Flat Tire
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a sma ll puncture, from a small nail for instance,
you can use the temporary tire repair kit so that you can drive to the nearest service
station for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe place.
1. Park the vehicle on a firm, level, and non-slippery surface. Apply the parking
brake.
2. Put the transmission into
(P.
3. Turn on the hazard warning lights an d set the power mode to VEHICLE OFF.
1Temporarily Repairing a Flat Tire
The kit should not be used in the following situations.
Instead, contact an authorized Acura NSX dealer or a
roadside assistant to have the vehicle towed.
•The tire sealant has expired.•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4 mm).•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.

6. Plug in the compressor to the accessory
power socket.
u Be careful not to pinch the cord in a
door or window.

7.Turn the power system on.
u Keep the power system on while
injecting sealant and air.
2 Carbon Monoxide Gas P. 70
8.Turn the air compressor on to inflate the
tire.
u The compressor starts injecting sealant
and air into the tire.
9. After the air pressure reaches 32 psi (220
kPa), turn off the compressor.
1Injecting Sealant and Air
NOTICE
Do not operate the temporary tire repair kit compressor
for more than 15 minutes. The compressor can overheat
and become permanently damagedM
Until the sealant injection is complete, the pressure
shown on the pressure gauge will appear higher than
actual. After the sealant injection is complete the
pressure will drop and then begi n to rise again as the tire
is inflated with air. This is normal. To accurately measure
the air pressure using the gauge, turn the air compressor
off only after the sealan t injection is complete.
If the required air pressure is not reached within 15
minutes, the tire may be too severely damaged for
the kit to provide the necessa ry seal and your vehicle
will need to be towed.
See an authorized Acura NSX dealer for a replacement
sealant bottle and proper disposal of an empty bottle.
3WARNING
Running the engine with the vehicle in an
enclosed or even partly enclosed area can
cause a rapid buildup of toxic carbon
monoxide.
Breathing this colorless, odorless gas can
cause unconsciousness and even death.
Only run the engine to power the air
compressor with th e vehicle outdoors.

10. Unplug the kit from the accessory power
socket.
11. Unscrew the sealant/ai r hose from the tire
valve stem. Reinstall the valve cap.
12. Push the deflation button until the gauge
returns 0 psi (0 kPa).
13. Apply the repair notification label to the
flat surface of the wheel.
u The wheel surface must be clean to
ensure the label adheres properly.

4. Recheck the air pressure using the gauge
on the air compressor.
u Do not turn the air compressor on to
check the pressure.
5. If the air pressure is:
• Less than 19 psi (130 kPa):
Do not add air or continue driving. The
leak is too severe. Call for help and have
your vehicle towed.

•32 psi (220 kPa) or more:
Continue driving for another five
minutes or until you reach the nearest
service station if less than five minutes
away. Do not exceed 50 mph (80 km/h).
u Stop and check the air pressure again. If
the air pressure does not go down after
the five minute drive, you do not need to
check the pressure any more. Drive to
the nearest service station to fix or
replace the tire.

Do not exceed 50 mph (80 km/h).
u You should repeat this procedure as long
as the air pressure is within this range.
