If you have a flat tire, see ªIn case of
emergencyº section.
Maximum inflation pressure
Do not exceed the maximum inflation pres-
sures shown on the side wall of the tire.
Tire inflation pressure
Periodically check the tire pressure (including
spare). Incorrect tire pressure may adversely
affect tire life and vehicle handling. Tire pres-
sure should be checked when tires are COLD.
Tires are considered COLD after the vehicle
has been parked for three or more hours, or
driven less than 1 mile (1.6 km). COLD tirepressures are shown on the tire placard affixed
to the center console lid.
The vehicle capacity weight is indicated
on the tire placard. Do not load your
vehicle beyond this capacity. Overload-
ing your vehicle may result in reduced
tire life, unsafe operating conditions due
to premature tire failure, or unfavorable
handling characteristics and could also
lead to a serious accident. Loading be-
yond the specified capacity may also
result in failure of other vehicle compo-
nents.
Before taking a long trip, or whenever
you have loaded your vehicle heavily,
use a tire pressure gauge to ensure that
the tire pressure is at the specified level.
Do not drive your vehicle over 85 MPH
(140 km/h) unless it is equipped with
high speed capability tires. Driving
faster than 85 MPH (140 km/h) may re-
sult in tire failure, loss of control and
possible injury.
Types of tires
When changing or replacing tires, be
sure all four tires are of the same type
(i.e., Summer, All Season or Snow) and
construction. Your NISSAN dealer may
be able to help you with information
about tire type, size, speed rating and
availability. Replacement tires may have
a lower speed rating than the factory
equipped tires, and may not match the
potential maximum vehicle speed. Never
exceed the maximum speed rating of the
tire.
All season tires
NISSAN specifies All Season tires on some
models to provide good performance for use
all year around, including snowy and icy road
conditions. All Season Tires are identified by
ªALL SEASONº and/or ªM&Sº on the tire side-
wall. Snow tires have better snow traction than
All Season tires and may be more appropriate
in some areas.

DOT (Department of Transportation) Quality
Grades: All passenger car tires must conform
to Federal Safety Requirements in addition to
these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified government
test courses. For example, a tire graded 150
would wear one and a half (1-1/2) times as well
on the government course as a tire graded
100. However, relative tire performance de-
pends on actual driving conditions, and may
vary significantly from the norm due to varia-
tions in driving habits, service practices and
differences in road characteristics and climate.
Traction A, B and C
Traction grades are A (the highest), B and C.
They represent a tire's ability to stop on wet
pavement as measured under controlled con-
ditions, on specified government test surfaces
of asphalt and concrete. A tire marked with a C
may have poor traction performance.
The traction grade assigned to your ve-
hicle tires is based on straight line brak-
ing traction tests and does not include
cornering (turning) traction.
Temperature A, B and C
Temperature grades are A (the highest), B,
and C. They represent a tire's resistance to
heat build-up, and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sus-
tained high temperature can cause tire mate-
rial to degenerate, reducing tire life. Excessive
temperatures can lead to sudden tire failure.
Grade C corresponds to a performance level
which all passenger car tires must meet under
the Federal Motor Vehicle Safety Standard No.
109. Grades A and B represent higher levels of
performance on laboratory test wheels than
the minimum required by law.
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and pos-
sible tire failure problems.
