Permissible load
(maximum gross
vehicle weight rat-
ing from the Tire
and Loading Infor-
mation placard
minus the gross
weight of all occu-
pants)
Vehicle identification plate
Even if you have calculated the total load
carefully, you should still make sure that the
gross vehicle weight rating and the gross axle
weight rating are not exceeded. Details can
be found on the vehicle identification plate on
the B-pillar on the driver's side of the vehicle
( page 316).

Gross vehicle weight rating: the gross
weight of the vehicle, all passengers, load and
trailer load/noseweight (if applicable) must
not exceed the gross vehicle weight rating.
Gross Axle Weight Rating (GAWR): the
maximum permissible weight that can be car-
ried by one axle (front or rear axle).
To ensure that your vehicle does not exceed
the maximum permissible values (gross vehi-
cle weight and maximum gross axle weight
rating), have your loaded vehicle (including
driver, occupants, load and full trailer load if
applicable) weighed on a suitable vehicle
weighbridge.
Trailer load/noseweight
The trailer load/noseweight affects the gross
weight of the vehicle. If a trailer is attached,
the trailer load/noseweight is included in the
load along with occupants and luggage. The
trailer load/noseweight is usually approx-
imately 10 % of the gross weight of the trailer
and its load.

Overview of Tire Quality Grading
Standards
Uniform Tire Quality Grading Standards are
U.S. government specifications. Their pur-
pose is to provide drivers with uniform relia-
ble information on tire performance data. Tire
manufacturers have to grade tires using three
performance factors: : tread wear grade, ;
traction grade and = temperature grade.
These regulations do not apply to Canada.
Nevertheless, all tires sold in North America
