Uniform Tire Quality
Grading System (UTQGS)
▼ Uniform Tire Quality Grading
System (UTQGS)
This information relates to the tire
grading system developed by the U.S.
National Highway
Tra ffi c Safety
Administration for grading tires by
tread wear, traction, and temperature
performance.
▼ Trea d Wea r
The tread wear 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-a-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 because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
▼
Traction-AA, A, B, C
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 braking (straight ahead)
traction tests and does not include
acceleration cornering (turning),
hydroplaning, or peak traction
characteristics.
▼ Te m p e ra t u r e - A , B , C
The temperature grades A (the
highest), B, and C, represent the tire's
resistance to the generation of heat
and its ability to dissipate heat when
tested under controlled conditions on
a specified indoor laboratory test
wheel.
Sustained high temperature can cause
the material of the tire to degenerate
and reduce tire life, and excessive
temperatures can lead to sudden tire
failure.

Grade C corresponds to a level of
performance which all passenger
vehicle tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the
minimum required by law.

Tread Wear, Traction and Temperature
Grades
Trea d wea r : The tread wear 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 (1 1/2) times as well on the
government course as a tire graded
100.
Tra c t i o n : The traction grades, from
highest to lowest are AA, A, B, and C.
The grades represent the tire's ability
to stop on wet pavement as measured
under controlled conditions on
specified government te
st surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
Temperature: The temperature grades
are A (the highest), B and C,
representing the tire's resistance to the
generation of heat and its ability to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local
governments may require true snow
tires, those with very deeply cut tread.
These tires should only be used in pairs
or placed on all four wheels. Make
sure you purchase snow tires that are
the same size and construction type as
the other tires on your vehicle.
SAFETY WARNING
The following safety warning appears
on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
EXPLOSION OF TIRE/RIM ASSEMBLY
DUE TO IMPROPER
MOUNTING-MATCH TIRE

NOTE
Tires degrade over time, even when
they are not being used on the road. It
is recommended that tires generally be
replaced when they are 6 years or
older. Heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process. You
should replace the spare tire when you
replace the other road tires due to the
aging of the spare tire. The period in
which the tire was manufactured (both
week and year) is indicated by a 4-digit
number.
Refer to Tire Labeling on page 8-24.
▼Safety Practices
The way you drive has a great deal to
do with your tire mileage and safety.
So cultivate good driving habits for
your own benefit.
Observe posted speed limits and
drive at speeds that are safe for the
existing weather conditions
Avoid fast starts, stops and turnsAvoid potholes and objects on the
road
Do not run over curbs or hit the tire
against the curb when parking
CAUTION
If you feel a sudden vibration or ride
disturbance while driving or you
suspect your tire or vehicle has been
damaged, immediately reduce your
speed. Drive with caution until you can
safely pull
off the road. Stop and
inspect the tire for damage. If the tire
is under-inflated or damaged, deflate
it, remove the tire and rim and replace
it with your spare tire. If you cannot
detect a cause, have the vehicle towed
to the nearest vehicle or tire dealer to
have the vehicle inspected.

WARNING
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so
will
affect the drive system which could
result in vehicle damage.
This section will guide you in the
proper loading of your vehicle, to keep
your loaded vehicle weight within its
design rating capability. Properly
loading your vehicle will provide
maximum return of vehicle design
performance. Before loading your
vehicle, familiarize yourself with the
following terms for determining your
vehicle's weight ratings, from the
vehicle's Safety Certification Label and
Tire and Load Information Label:
WARNING
Overloaded Vehicle:
Overloading a vehicle is dangerous.
The results of overloading can have
serious consequences in terms of
passenger safety. Too much weight on
a vehicle's suspension system can
cause spring or shock absorber failure,
brake failure, handling or steering
problems, irregular tire wear, tire
failure or other damage.

Tire Information (U.S.A.)
8-31
CX-30_8JP5-EA-20K_Edition1_new 2020-7-22 15:50:09

Overloading makes a vehicle harder to
drive and control. It also increases the
distance required for stopping. In cases
of serious overloading, brakes can fail
completely, particularly on steep
grades. The load a tire will carry safely
is a combination of the size of the tire,
its load range, and corresponding
inflation pressure.
Never overload the vehicle and always
observe the vehicle's weight ratings
from the vehicle's Safety Certification
and Tire and Load Information labels.Base Curb Weight is the weight of the
vehicle including a full tank of fuel
and all standard equipment. It does
not include passengers, cargo, or
optional equipment.

Vehicle Curb Weight is the weight of
your new vehicle when you picked it
up from your dealer plus any
aftermarket equipment.

PAY LOA D
Pay l o a d is the combination weight of
cargo and passengers that the vehicle
is designed to carry. The maximum
payload for your vehicle can be found
on the Tire and Load Information label
on the driver's door frame or door
pillar. Look for “THE COMBINATION
WEIGHT OF OCCUPANTS AND
CARGO SHOULD NEVER EXCEED XXX
kg or XXX lbs” for your maximum
payload. The payload listed on the tire
label is the maximum payload for the
vehicle as built by the assembly plant.
If any aftermarket or dealer installed
equipment has been installed on the
vehicle, the weight of the equipment
must be subtracted from the payload
listed on the tire label in order to be
accurate.
