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 left 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.Tire Service Life
The service life of your tires is
dependent on many factors,
including, but not limited to, driving
habits, road conditions, vehicle
loading, inflation pressure,
maintenance history, speed, and
environmental conditions (even
when the tires are not in use).
In addition to your regular
inspections and inflation pressure
maintenance, it is recommended that
you have annual inspections
performed once the tires reach five
years old. It is also recommended
that all tires, including the spare, be
removed from service after 10 years
from the date of manufacture,
regardless of their condition or state
of wear.
The last four digits of the TIN (tire
identification number) are found on
the sidewall of the tire and indicate
the date of manufacture (See
Tire
Labeling on page 484). Tire Maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
Have your dealer check the tires if
you feel a consistent vibration while
driving. A tire should always be
rebalanced if it is removed from the
wheel. When you have new tires
installed, make sure they are
balanced. This increases riding
comfort and tire life. For best results,
have the installer perform a dynamic
balance.
Improper wheel weights can damage
your vehicle's aluminum wheels. Use
only Acura wheel weights for
balancing.

This section covers the more
common problems that motorists
experience with their vehicles. It
gives you information about how to
safely evaluate the problem and what
to do to correct it. If the problem has
stranded you on the side of the road,
you may be able to get going again. If
not, you will also find instructions on
getting your vehicle towed.Compact Spare Tire

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 inflation pressure of the
compact spare tire every time you
check the other tires. It should be
inflated to:
60 psi (420 kPa , 4.2 kgf/cm
2)Follow these precautions:
●Never exceed 50 mph (80 km/h).●This tire gives a harsher ride and
less traction on some road
surfaces. 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 the
same make and model.●After the flat tire is replaced with
the spare tire, the low tire
pressure/TPMS indicator stays on.
After several miles (kilometers)
driving with the spare, this
indicator begins to flash, then
stays on again. You will also see a
‘‘
CHECK TPMS SYSTEM ’’
message on the multi-information
display (see page 393).
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 for mounting a regular tire.

If you have a flat tire while driving,
stop in a safe place to change it.
Drive slowly along the shoulder until
you get to an exit or an area that is
far away from the traffic lanes.
The vehicle can easily roll off
the jack, seriously injuring
anyone underneath.
Follow the directions for
changing a tire exactly, and
never get under the vehicle
when it is supported only by the
jack.1. Park the vehicle on firm, level, and
non-slippery ground. Put the
transmission in Park. Apply the
parking brake.
If you are towing a trailer, unhitch
it.
2. Turn on the hazard warning lights, and turn the ignition switch to the
LOCK (0) position. Have all
passengers get out of the vehicle
while you change the tire.
3. Open the tailgate. Raise the cargoarea floor lid by lifting it up with
the strap, then remove the lid.
The spare tire, jack, and tools are
under the cargo area floor.
4. Unscrew the wing bolt. Use the hooked end of the wheel nut
wrench extension as a wrench if
the wing bolt is hard to loosen.
Then take the spare tire out of the
cargo area.WING BOLT

8. Use the extension and the wheelnut wrench as shown to raise the
vehicle until the flat tire is off the
ground.
9. Remove the wheel nuts, then remove the flat tire. Handle the
wheel nuts carefully; they may be
hot from driving. Place the flat tire
on the ground with the outside
surface facing up.
10. Before mounting the spare tire, wipe any dirt off the mounting
surface of the wheel and hub with
a clean cloth. Wipe the hub
carefully; it may be hot from
driving. 11. Put on the spare tire. Put the
wheel nuts back on finger-tight,
then tighten them in a crisscross
pattern with the wheel nut wrench
until the wheel is firmly against the
hub. Do not try to tighten the
wheel nuts fully.
12. Lower the vehicle to the ground, and remove the jack.

13. Tighten the wheel nuts securely inthe same crisscross pattern. Have
the wheel nut torque checked at
the nearest automotive service
facility.
Tighten the wheel nuts to:
80 lbf·ft (108 N·m, 11 kgf·m)
14. Store the jack in its holder. Turn the jack's end bracket to lock it in
place. Store the tools.
15. Remove the center cap from theflat tire, and store it in the cargo
area.
16. Place the flat tire face up in the cargo area.
17. Secure the flat tire by screwing the wing bolt back into its hole.
Loose items can fly around the
interior in a crash and could
seriously injure the occupants.
Store the wheel, jack, and tools
securely before driving.
18. Reinstall the cargo area floor, and close the tailgate.
19. Your vehicle's original tire has a tire pressure monitoring system
sensor. To replace a tire, refer to
Changing a Tire with TPMS (see
page 394).

Glossary of Tire Terminology
Cold Tire Pressure-The tire air
pressure when the vehicle has been
parked for at least three hours or
driven less than 1 mile (1.6 km).
Load Rating -Means the maximum
load that a tire is rated to carry for a
given inflation pressure.
Maximum Inflation Pressure -The
maximum tire air pressure that the
tire can hold.
Maximum Load Rating -Means the
load rating for a tire at the maximum
permissible inflation pressure for that
tire.
Recommended Inflation Pressure -
The cold tire inflation pressure
recommended by the manufacturer.
Treadwear Indicators (TWI) -
Means the projections within the
principal grooves designed to give a
visual indication of the degrees of
wear of the tread. Tire Pressure Monitoring System
(TPMS)
-Required Federal
Explanation
Each tire, including the spare (if
provided), should be checked
monthly when cold and inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label.
(If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.) As an added safety feature, your
vehicle has been equipped with a tire
pressure monitoring system (TPMS)
that illuminates a low tire pressure
telltale
when one or more of your tires is
significantly under-inflated
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure.
