2024 MAZDA CX90 tires

Inspecting the Tires
About Tires
For reasons of proper performance,
safety, and better energy efficiency,
always maintain recommended tire
inflation pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using Different Tire Types.
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires.
Using any other tire size than what is
specified for the vehicle (page
10-71)is dangerous. It could seriously
affect ride, handling, ground
clearance, tire clearance, and
speedometer calibration. This could
cause you to have an accident. Use
only tires that are the correct size
specified for the vehicle.

Inspecting tire inflation pressure
WARNING
Always inflate the tires to the correct
pressure.
Overinflation or underinflation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 10-71.
Use only a Mazda-genuine tire valve
cap.
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tire valve cap that is not a
Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended
pressures for the best ride, handling ,
and minimum tire wear.
Refer to the specification charts (page
10-71).
NOTE
Cold inflation pressure
The cold inflation pressure is the
pressure measured under ambient
temperatures before the vehicle is
driven.
Maximum inflation pressure
The maximum inflation pressure is
the upper limit of the cold inflation
pressure designated by the tire
manufacturer.
Recommended inflation pressure
The recommended inflation pressure
is the cold inflation pressure
necessary for maintaining the
performance of your Mazda.
Underinflation or overinflation can
cause a harsh ride, reduced fuel
economy, a greater possibility of
damage from road hazards, uneven
and accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.

Keep your tire pressure at the correct
levels. If one frequently needsinflating, have it inspected.Rotating the Tires
WARNING
Rotate tires periodically.
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking , rotate the tires periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tire rotation interval.
During rotation, inspect them for
correct balance.


Do not include (TEMPORARY USE
ONLY) spare tire in rotation.
Also, inspect them for uneven wear
and damage. Abnormal wear is usually
caused by one or a combination of the
following:

Incorrect tire pressureImproper wheel alignmentOut-of-balance wheelSevere braking

After rotation, inflate all tire pressures
to specification (page 10-71) and
inspect the lug nuts for tightness.

CAUTION
Rotate unidirectional tires and radial
tires that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tire performance
will be reduced if rotated from side to
side.
Replacing a Tire or aWheel
WARNING
Always use tires that are in good
condition.
Driving with worn tires is dangerous.
Reduced braking , steering , and
traction could result in an accident.
Replace all four tires at the same
time.
Replacing just one tire is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tires at the
same time.
Always use wheels of the correct size
on your vehicle.
Using a wrong-sized wheel is
dangerous. Braking and handling could
be affected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:
 Tire fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.

CX-90_8KG7-EA-22L_Edition1_new 2022-11-17 16:05:04

Replace the tire when this happens.
1. New tread
2. Worn tread
3. Tread wear indicator

You should replace the tire before the
band crosses the entire tread.
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 10-30.
Replacing Light Bulbs
All the light bulbs are the LED type.
The LED bulb cannot be replaced as a
single unit because it is an integrated
unit.
The LED bulb has to be replaced with
the unit. If a replacement is necessary,
consult an Authorized Mazda Dealer.
Adjusting the Headlight Aim
If the headlight cannot be adjusted
using procedure below, consult an
Authorized Mazda Dealer.
1. Make sure the vehicle has a fulltank of gasoline and the area
around the headlight is not
deformed.
2. Park the vehicle on level ground.
3. Sit in the driver's seat.
4. Bounce the vehicle several times.
5. Using a Phillips-head screw-driver, turn bolt A in either direction.
Remember the turning direction
and the number of turns.
6. Turn bolt B the same number of turns and in the same direction as
step 5.

1. Adjustment bolt A
2. Adjustment bolt B

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.

CX-90_8KG7-EA-22L_Edition1_new 2022-11-17 16:05:04

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.
Temperature-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.
WARNING
Keep your vehicle's tires properly
inflated and not overloaded.
Driving with improperly inflated or
overloaded tires is dangerous.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure. The
temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded.

These grades will be added to the
sidewalls of passenger vehicle tires
over the next several years according to
a schedule established by the NHTSA
and the tire manufacturers.
