Vehicle specifications
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement a s
measured under controlled conditions on specified government te st
surfaces of asphalt and concrete.
A tire marked C may have p oor traction performance.
Warning: The traction grade assigned to this tire is based on b raking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■Temperature A, B, C
The temperature grades are A ( the highest), B, and C, representing
the tire’s resistance to the ge neration of heat and its ability to dissi-
pate heat when tested under contr olled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can c ause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passeng er
car tires must meet under the Fe deral Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades of a tire assume that it is pro perly
inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can c ause heat buildup and possible t ire
failure.

For owners
Secure loose items to prevent weight shifts that could affect the bal-
ance of your vehicle. When the truck camper is loaded, drive to a
scale and weigh on the front and on the rear wheels separately to
determine axle loads. Individual axle loads should not exceed e ither
of the Gross Axle Weight Ratings (GAWR). The total of the axle loads
should not exceed the Gross Vehicle Weight Rating (GVWR). These
ratings are given on the vehicle certification label which is located on
the door latch post on the le ft side of the vehicle. (P. 599) If weight
ratings are exceeded, move or remove items to bring all weights
below the ratings.

■ Overloading
Be careful — overloading can cause dangerous braking and handli ng prob-
lems, and can damage your vehicle and its tires.
