2018 NISSAN ALTIMA SL Owners Manual

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, refer to “Checking
tire pressure” in this section.
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.

3Tire 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 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 inflation pressure.
5Maximum load rating
This number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When re-
placing the tires on the vehicle, always
use a tire that has the same load rat-
ing as the factory installed tire.
6Term of “tubeless” or “tube type”
Indicates whether the tire requires
an inner 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 defined throughout this section,
Intended Outboard Sidewall is (1) the
sidewall that contains a whitewall,
bears white lettering or bears
manufacturer, brand, and/or model
name molding that is higher or
deeper than the same molding on
the other sidewall of the tire, or (2)
the outward facing sidewall of an
asymmetrical tire that has a particu-
lar side that must always face out-
ward when mounted on a vehicle.
TYPES OF TIRES

∙ Always use tires of the same type,size, brand, construction and tread
pattern on all four wheels. Failure to
do so may result in a circumference
difference between tires on the front
and rear axles which can cause the
Vehicle Dynamic Control (VDC) system
to malfunction resulting in personal
injury or death, excessive tire wear
and may damage the transmission
and differential gears.
∙ For additional information regarding tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
