Example 2B

For example, if a person weighing
143 lbs (65 kg) and a child weighing
40 lbs (18 kg) now enter the same
vehicle (bringing the number of
occupants to three), and a child
restraint system weighing 11 lbs (5
kg) is installed in the vehicle for the
child to use, the calculations are as
follows.

1.

Calculate the total weight.

2.

Calculate the available load ca-

pacity.

3.

The total weight now exceeds

the capacity weight by 32 lbs (15
kg), so the cargo weight must be
reduced by 32 lbs (15 kg) or more.

13-4. Uniform tire quality
grading standards

This information indicates the rela-
tive performance of passenger car
tires in the area of treadwear,
traction, and temperature resis-
tance. This is to aid the consumer
in making an informed choice in the
purchase of tires.
Quality grades can be found where
applicable on the tire sidewall be-
tween tread shoulder and maximum
section width.
For example:

TREADWEAR 200 TRACTION AA
TEMPERATURE A

The quality grades apply to new
pneumatic tires for use on passen-
ger cars. However, they do not
apply to deep tread, winter type
snow tires, space-saver or tempor-
ary use spare tires, tires with
nominal rim diameters of 12 inches
or less, or to some limited produc-
tion tires.

510

(513,1)

All passenger car tires must con-
form to Federal Safety Require-
ments in addition to these grades.

&

TREADWEAR

The treadwear grade is a compara-
tive rating based on the wear rate of
the tire when tested under con-
trolled conditions on a specified
government test course.
For example, a tire graded 150
would wear one and one-half (1-
1/2) times as well on the govern-
ment course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use, however, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.

&

TRACTION AA, A, B, C

The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades represent the tire’s ability to
stop on wet pavement as measured

under controlled conditions on spe-
cified government test surfaces of
asphalt and concrete.
A tire marked C may have poor
traction performance.

WARNING

The traction grade assigned to
this tire is based on straight-
ahead braking traction tests,
and does not include accelera-
tion, cornering, hydroplaning,
or peak traction characteris-
tics.

&

TEMPERATURE A, B, C

The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled con-
ditions on a specified indoor labora-
tory test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and

excessive temperature can lead to
sudden tire failure.
The grade C corresponds to a level
of performance which all passenger
car tires must meet under the
Federal Motor Vehicle Safety Stan-
dards No. 109.
Grades B and A represent higher
levels of performance on the la-
boratory test wheel than the mini-
mum required by law.

WARNING

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 combination, can cause
heat buildup and possible tire
failure.

13-5. Reporting safety de-
fects (U.S.A.)

If you believe that your vehicle has a
defect which could cause a crash or
could cause injury or death, you
should immediately inform the Na-
tional Highway Traffic Safety Ad-
ministration (NHTSA) in addition to
notifying Subaru of America, Inc.
If NHTSA receives similar com-
plaints, it may open an investiga-
tion, and if it finds that a safety
defect exists in a group of vehicles,
it may order a recall and remedy
campaign. However, NHTSA can-
not become involved in individual
problems between you, your dealer,
or Subaru of America, Inc.
To contact NHTSA, you may call the
Vehicle Safety Hotline toll-free at 1-
888-327-4236 (TTY: 1-800-424-
9153); go to
http://www.safercar.gov; or write to:
Administrator, NHTSA, 1200 New
Jersey Avenue, SE, West Building,
Washington, DC 20590. You can

also obtain other information about
motor vehicle safety from http://
www.safercar.gov.
