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 % - 15 % of the gross weight
of the trailer and its cargo.

Direction of rotation
Tires with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of hydroplaning. You will only gain these
benefits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tire indicates
its correct direction of rotation.
You may mount an emergency spare wheel/
spare wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the
emergency spare wheel/spare wheel.
Uniform Tire Quality Grading
Standards
Overview of tire quality standards
The 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 grade tires using three
performance factors: tread wear :, tire
traction ; and heat resistance =. All tires
sold in North America are provided with the
corresponding quality class mark on the
sidewall of the tire, even though these
regulations do not apply to Canada.
