Department Of Transportation Uniform Tire Quality Grades; Treadwear; Traction Grades - Alfa Romeo Giulia 2024 Owner's Manual

In the case of irregular wear of the tires identify the
cause and correct it as soon as possible, by contacting
an authorized dealer.
Tire Rotation for Directional Tires — If Equipped
Directional tires are equipped on the following:
□
2.0T GME Engine equipped with same size tires and
wheels on front and rear axles
The rotational direction of the tire must be taken into
consideration when rotating the tires. The
recommended rotation pattern for directional tires is
shown in the following diagram.
Tire Rotation
All Wheel Drive (AWD) Models
It is recommended to avoid situations with a large
difference in wear between the front and rear tires and
to strictly use Winter tires of the sizes given on the tire
placard.
The AWD system and the original tires are developed
together to ensure the vehicle's best performance.
When changing the tires, it is recommended to us the
same "AR" marked tires, to maintain the same level of
performance and component life.

UNIFORM TIRE QUALITY
GRADES
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of
the tires on your vehicle.
All passenger vehicle tires must
conform to Federal safety
requirements in addition to these
grades.
T
READWEAR
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
T G
RACTION RADES
The Traction grades, from highest to
lowest, are AA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING!
The traction grade assigned to this
tire is based on straight-ahead
braking traction tests, and does not
include acceleration, cornering,
hydroplaning, or peak traction
characteristics.
