Checking/correcting tire
pressure
,..Check the tire pressure at least
once per month and also check it
before every long drive .
.,..Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
.,.Check the Labe l ¢fig. 277for
the correct tire pressure based
on vehicle load.
.,..Correct the tire pressure if nec­
essary .

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex ­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories , a full tank of
fuel, oil, coolant and other fluids
Wheels
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of
150 lbs (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load .
The
Gross Axle Weight Rating
( " GAWR ") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle 's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
.,.

Wheels
are listed on the safety compli­
ance sticker on the driver's side B­ pillar respectively on the front
end of the driver's door.
& WARNING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that
has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss of control and a crash .
-Always make sure that the to­ tal load being transported -
including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.

Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload ­
ed.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OCCU­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS" on your vehicle's placard
(tire inflation pressure label)
¢ page 344, fig. 277.
2. Determine the combined
weight of the driver and pas­ sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from
"XXX" kilograms or "XXX"
pounds shown on the stick­
er ¢ page 344, fig. 2 77.
4. The resulting figure equals the
available amount of cargo and luggage load capacity . For ex­
ample, if the "XXX" amount
equals 1400 lbs. and there will

Low -profile tires can wear out faster than stand­

Uniform tire quality grading
-Tread wear
- Traction AA AB C
- T emperature ABC
Qual ity grades can be found where app licable on
the t ire side wa ll between tread shou lde r and
maximum sect ion w idth
¢page 334, fig. 274.
For e xample : Tread wear 200 , Traction AA, Tem­
pe rature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread w ear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov­
ernment test course.
F or example, a tire graded 150 would wear one
and one ha lf
(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 significant ly from the norm due to
variations in driving hab its, service practices and
d ifferences i n road characteristics and climate.
Tracti on
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ab ility to stop on wet pavement as measured un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete . A tire
marked C may have poor traction performance
¢ _& .
Temper ature
The temperature grades are A (the h ighest), B,
and C, representing the tire's resistance to the
Wh eel s
generat ion of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained h igh temperature can cause the mate­
ria l 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 per form ­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
No. 109. Grades Band A represe nt higher levels
of performance on the laboratory test wheel than
the minimum requ ired by law.
A WARNING c,...._ -
The tract ion grade assigned to this t ire is
based on straight-ahead braking traction
tests, and does not include acceleration, co r­
nering, hyd roplaning or pea k traction cha rac­
terist ics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded . Excessive speed, underinfla­
tion, or excessive loading, either separately or
i n comb inat ion, can cause heat bu ildup and
possib le tire fai lure.
A WARNING
-Temperature grades apply to tires that are
properly inflated and not over or under inflat­
ed.
