2021 NISSAN MAXIMA tire pressure

4. Lower the vehicle slowly until the tiretouches the ground. Then, with the
wheel nut wrench, tighten the wheel
nuts securely in the sequence illustrated
(
OA,OB,OC,OD,OE). Lower the vehicle
completely.
WARNING
• Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
• Do not use oil or grease on the wheel
studs or nuts. This could cause the
nuts to become loose.
• Retighten the wheel nuts when the
vehicle has been driven for 600 miles
(1,000 km) (also in cases of a flat tire,
etc.).
As soon as possible, tighten the wheel
nuts to the specified torque with a
torque wrench.
Wheel nut tightening torque: 83 f t-lb (113 N·m) The wheel nuts must be kept tightened
to specification at all times. It is recom-
mended that wheel nuts be tightened to
specifications at each lubrication
interval.
Adjust tire pressure to the COLD
pressure.
COLD pressure: Af ter vehicle has been
parked for 3 hours or more or driven less
than 1 mile (1.6 km).
COLD tire pressures are shown on the
Tire and Loading Information label af-
fixed to the driver's door opening.
5. Securely store the flat tire and jacking
equipment in the vehicle.
6. Place the spare tire cover and the trunk floor carpeting over the damaged tire.
7. Close the trunk.
NOTE:
You may need to remove the wheel cap
in order to secure the damaged tire us-
ing the spare tire clamp.
WARNING
• Always make sure that the spare tire
and jacking equipment are properly
secured af ter use. Such items can be-
come dangerous projectiles in an ac-
cident or sudden stop.
• The spare tire is designed for emer-
gency use. For additional informa-
tion, see specific instruction under
the heading “Wheels and tires”
(P. 8-26).

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
WARNING
Radio waves could adversely af-
fect electric medical equipment.
Those who use a pacemaker
should contact the electric medi-
cal equipment manufacturer for
the possible influences before
use.
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS).
It monitors tire pressure of all tires
except the spare. When the low tire
pressure warning light is lit and the
“Tire Pressure Low - Add Air” warning
appears in the vehicle information
display, one or more of your tires is
significantly under-inflated. If equipped, the system also displays
pressure of all tires (except the spare
tire) on the display screen by send-
ing a signal from a sensor that is
installed in each wheel.
The TPMS will activate only when the
vehicle is driven at speeds above 16
mph (25 km/h). Also, this system
may not detect a sudden drop in tire
pressure (for example a flat tire while
driving).
For additional information, see “Low
tire pressure warning light” (P. 2-12),
“Tire Pressure Monitoring System
(TPMS)” (P. 5-5) and “Flat tire” (P. 6-3).
Tire inflation pressure
Check the tire pressures (including
the spare) of ten and always prior to
long distance trips. The recom-
mended tire pressure specifications
are shown on the F.M.V.S.S./C.M.V.S.S.
certification label or the Tire and
Loading Information label under the
LDI2135
Trunk light
WHEELS AND TIRES
8-26Do-it-yourself

"Cold Tire Pressure" heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
• Most tires naturally lose air overtime.
• Tires can lose air suddenly when driven over potholes or other ob-
jects or if the vehicle strikes a curb
while parking.
The tire pressures should be
checked when the tires are cold. The
tires are considered COLD af ter the
vehicle has been parked for 3 or
more hours, or driven less than 1 mile
(1.6 km) at moderate speeds.
The TPMS with Easy-Fill Tire Alert
provides visual and audible signals
outside the vehicle for inflating the
tires to the recommended COLD tire
pressure. For additional information,
see “TPMS with Easy-Fill Tire Alert”
(P. 5-7). If the tires are used at speeds above
100 mph (162 km/h) where it is legal
to do so (on a race track for ex-
ample), the cold tire inflation pres-
sure must be increased. For addi-
tional information, see “Checking tire
pressure” (P. 8-30).
Set the tire pressure to the normal
cold tire inflation pressure when the
vehicle speed or load is reduced.
Incorrect tire pressure, including
under inflation, may adversely af-
fect tire life and vehicle handling.
WARNING
• Improperly inflated tires can
fail suddenly and cause an
accident. •
The Gross Vehicle Weight Rat-
ing (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. certifica-
tion label. The vehicle weight
capacity is indicated on the Tire
and Loading Information label
(if so equipped). Do not load
your vehicle beyond this ca-
pacity. Overloading your ve-
hicle may result in reduced tire
life, unsafe operating condi-
tions due to premature tire fail-
ure, or unfavorable handling
characteristics and could also
lead to a serious accident.
Loading beyond the specified
capacity may also result in fail-
ure of other vehicle
components.
Do-it-yourself8-27

•Before taking a long trip, or
whenever you heavily load
your vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
• Increase the cold tire inflation
pressure as indicated in
"Checking tire pressure" in this
section when using the tires
specified by NISSAN above 100
mph (162 km/h) where it is le-
gal to do so (on a race track for
example). Failure to increase
the cold tire inflation pressure
may result in tire failure, loss of
control and possible injury. Af-
ter such use, readjust tire
pressure. •
For additional information re-
garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

3Cold tire pressure: Inflate the tires
to this pressure when the tires

COLD af ter the vehicle has been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at

mended cold tire inflation is set
by the manufacturer to provide
the best balance of tire wear, ve-

noise, etc., up to the vehicle's
GVWR.

Checking tire pressure
1. Remove the valve stem cap fromthe 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 to the
specification 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 release air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires, including the spare.

TIRE LABELING
Federal law requires tire manufac-
turers to place standardized infor-
mation on the sidewall of all tires.
This information identifies and de-
scribes the fundamental character-
istics of the tire and also provides the
Tire Identification Number (TIN) for
safety standard certification. The TIN
can be used to identif y the tire in
case of a recall.
LDI0393WDI0394
Example

O2TIN (Tire Identification Number)
for a new tire (example: DOT XX XX
XXX XXXX)
1. DOT: Abbreviation for the “Depart- ment Of Transportation”. The
symbol can be placed above, be-
low or to the lef t or right of the Tire
Identification Number.
2. Two-digit code: Manufacturer's identification mark. 3. Two-digit code: Tire size.
4. Three-digit code: Tire type code
(Optional).
5. Four numbers represent the week and year the tire was built.
For example, the numbers 3103
means the 31st week of 2003. If
these numbers are missing then
look on the other sidewall of the
tire.
O3Tire ply composition and material
The number of layers or plies of
rubber-coated fabric in the tire. Tire
manufacturers also must indicate
the materials in the tire, which in-
clude steel, nylon, polyester and
others.
O4Maximum permissible inflation
pressure
This number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure.
O5Maximum load rating
This number indicates the maxi-
mum load in kilograms and pounds
that can be carried by the tire. When
replacing the tires on the vehicle, al-
ways use a tire that has the same
load rating as the factory installed
tire.
