climate control NISSAN SENTRA 1998 B14 / 4.G Owners Manual

DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment 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 depends on actual
driving conditions, and may vary signifi-
cantly due to variations in driving habits,
service practices and differences in road
characteristics and climate.
Traction AA, A, B and C
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent a tire's ability to stop on wet pavement
as measured under controlled conditions,
on specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight-ahead
braking traction tests, and does notinclude acceleration cornering, hydro-
planing, or peak traction characteris-
tics.
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 condi-
tions on a specified indoor laboratory test
wheel. Sustained high temperature can
cause tire material 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 perfor-
mance on laboratory test wheels than the
minimum required by law.
WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, under inflation, or excessive
loading, either separately or in combi-
nation, can cause heat build-up and
possible tire failure problems.Your NISSAN is covered by the following
