Vehicle identification plate

Even if you have calculated the total cargo

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 412).

Permissible gross vehicle weight: the

gross weight of the vehicle, all passengers,

load and trailer load/noseweight (if

applicable) must not exceed the permissible

gross vehicle weight.
Gross axle weight rating: the maximum

permissible weight that can be carried by one

axle (front or rear axle).
To ensure that your vehicle does not exceed

the maximum permissible values (gross

vehicle weight and maximum gross axle

weight rating), have your loaded vehicle

(including driver, occupants, cargo, 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

approximately 8% of the gross weight of the

trailer and its cargo.

Uniform Tire Quality Grading

Standards

Overview of Tire Quality Grading

Standards

Uniform Tire Quality Grading Standards are

U.S. government specifications. Their

purpose is to provide drivers with uniform

reliable 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 are provided with the corresponding

quality grading markings on the sidewall of

the tire.
Where applicable, the tire grading

information can be found on the tire sidewall

between the tread shoulder and maximum

tire width.
