2018 INFINITI QX30 inflation pressure

TIRE INFLATION PRESSURE
Checking 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 escap-
ing 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 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, in-
cluding the spare.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the side-
wall of all tires. This information identifies
and describes the fundamental characteris-
tics of the tire and also provides the tire iden-
tification number (TIN) for safety standard
certification. The TIN can be used to identify
the tire in case of a recall.

Example
8-30Do-it-yourself

1Tire size (example: P215/60R16 94H)
1 P: The “P” indicates the tire is designed for
passenger vehicles. (Not all tires have this
information.)
2 Three-digit number (215): This number
gives the width in millimeters of the tire
from sidewall edge to sidewall edge.
3 Two-digit number (60): This number,
known as the aspect ratio, gives the tire’s
ratio of height to width.
4 R: The “R” stands for radial.
5 Two-digit number (16): This number is the
wheel or rim diameter in inches.
6
Two- or three-digit number (94): This num-
ber is the tire’s load index. It is a measurement
of how much weight each tire can support.
You may not find this information on all tires
because it is not required by law.
7H:Tire speed rating. You should not drive the
vehicle faster than the tire speed rating.
2TIN (Tire Identification Number) for a new
tire (example: DOT XX XX XXX XXXX)
1 DOT: Abbreviation for the “Department of
Transportation”. The symbol can be placed
above, below or to the left or right of the
Tire Identification Number.
2 Two-digit code: Manufacturer’s identifi-
cation 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.
3Tire ply composition and material
The number of layers or plies of rubber-
coated fabric in the tire. Tire manufactur-
ers also must indicate the materials in thetire, which include steel, nylon, polyester,
and others.
4Maximum 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 in-
flation pressure.
5Maximum load rating
This number indicates the maximum load
in kilograms and pounds that can be car-
ried by the tire. When replacing the tires
on the vehicle, always use a tire that has
the same load rating as the factory in-
stalled tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires an in-
ner tube (“tube type”) or not (“tubeless”).
7The word “radial”
The word “radial” is shown, if the tire has
radial structure.
8Manufacturer or brand name”
Manufacturer or brand name is shown.
Other tire-related terminology:
In addition to the many terms that are de-
fined throughout this section, Intended Out-
board Sidewall is (1) the sidewall that con-
tains a whitewall, bears white lettering or
bears manufacturer, brand and/or model
