Checking the tire pressure 1. Remove the valve stem cap from the
tire.
2. Press the pressure gauge squarely
onto the valve stem. Do not press
too hard or force the valve stem
sideways, or air will escape. If the
hissing sound of air escaping from
the tire is heard while checking the
pressure, reposition the gauge to
eliminate this leakage. 3. Remove the gauge.
4. Read the tire pressure on the gauge
stem and compare it to the specifi-
cation shown on the Tire and
Loading Information label.
5. Add air to the tire as needed. If too
much air is added, press the core of
the valve stem briefly with the tip of
the gauge stem to release pressure.
Recheck the pressure and add or re-
lease air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires,
including the spare. (Refer to the

to place standardized information on
the sidewall of all tires. This informa-
tion identifies and describes the funda-
mental characteristics of the tire and
also provides the tire identification
number (TIN) for safety standard certifi-
cation. The TIN can be used to identify
the tire in case of a recall. q 1
Tire size (example: P215/65R15 95H)
1. P: The ªPº indicates the tire is de-
signed for passenger vehicles. (Not
all tires have this information).
2. Three-digit number (215): This
number gives the width in millime-
ters of the tire from sidewall edge to
sidewall edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives the
tire's ratio of height to width. SDI1575

O Do not use abrasive cleaners when
washing the wheels.
O Inspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.
O INFINITI recommends that the road
wheels be waxed to protect against
road salt in areas where it is used
during winter.
Spare tire (TEMPORARY USE ONLY
spare tire (T-type)) Observe the following precautions if the
T-type spare tire must be used, otherwise
your vehicle could be damaged or in-
volved in an accident.
CAUTIONO The T-type spare tire should be used only
for an emergency. It should be replaced by
a standard tire at the first opportunity.
O Drive carefully while the T-type spare tire
is installed.
Avoid sharp turns and abrupt braking
while driving. O Periodically check the T-type spare tire
inflation pressure, and always keep it at
60 psi (420 kPa, 4.2 bar).
O With the T-type spare tire installed, do
not drive your vehicle at speeds faster
than 50 MPH (80 km/h).
O When driving on roads covered with
snow or ice, the T-type spare tire should
be used on the front wheel and the origi-
nal tire used on the rear wheels (drive
wheels). Use tire chains only on the rear
two original tires (Sedan).
O
Tire tread of the T-type spare tire will wear
at a faster rate than the original tire. Re-
place the T-type spare tire as soon as the
tread wear indicators appear.
O Do not use the T-type spare tire on other
vehicles.
O Do not use more than one T-type spare
tire at the same time.
O Do not tow a trailer while the T-type
spare tire is installed. CAUTION O Do not use tire chains on a T-type spare
tire. Tire chains will not fit properly on
the T-type spare tire and may cause
damage to the vehicle.
O Because the T-type spare tire is smaller
than the original tire, ground clearance
is reduced. To avoid damage to the ve-
hicle do not drive over obstacles. Also do
not drive the vehicle through an auto-
matic car wash since it may get caught.
