2012 NISSAN LEAF Owners Manual

Incorrect tire pressure, including un-
der inflation, may adversely affect tire
life and vehicle handling.

5.Three-digit code: Date of Manufacture
6.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 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 replacing
the tires on the vehicle, always use a
tire that has the same load rating as the
factory installed tire.
*6Term of “tubeless” or “tube type”
Indicates whether the tire requires aninner tube (“tube type”) or not (“tube-
less”) .
*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 particular
side that must always face outward when
mounted on a vehicle.
TYPES OF TIRES

CHANGING WHEELS AND TIRES
Tire rotation
NISSAN recommends rotating the tires
every 7,500 miles (12,000 km) .
As soon as possible, tighten the wheel
nuts to the specified torque using a
torque wrench.
Wheel nut tightening torque:80 ft-lb (108 N·m)
The wheel nuts must be kept tigh-
tened to the specification at all times.
It is recommended that wheel nuts be
tightened to the specification at each
tire rotation interval.

.The original tires have built-in
tread wear indicators. When
wear indicators are visible, the
tire(s) should be replaced.
.Tires degrade with age and use.
Have tires, over 6 years old
checked by a qualified techni-
cian, because some tire damage
may not be obvious. Replace the
tires as necessary to prevent tire
failure and possible personal
injury.
.For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. See “Specifications” in
the “9. Technical and consumer information”
section for recommended types and sizes of
tires and wheels.
