Spare Tire
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the rear wheels (driving wheels).
Driving with the temporary spare tire
on one of the rear driving wheels is
dangerous. Handling will be affected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the rear wheel and install the
temporary spare tire to the front.
CAUTION
When using the temporary spare tire,
driving stability may decrease
compared to when using only the
conventional tire. Drive carefully.
 To avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also,
do not drive through an automatic
car wash. This tire's diameter is
smaller than a conventional tire, so
the ground clearance is reduced.
 Do not use a tire chain on this tire
because it will not fit properly.
 Do not use your temporary spare
tire on any other vehicle, it has
been designed only for your
Mazda.
Use only one temporary spare tire
on your vehicle at the same time.
To remove the spare tire
1. Remove the luggage board.

Locking Lug Nuts
If your Mazda is equipped with the
optional antitheft wheel lug nuts, a
special key must be used to unlock the
locking lug nut for each wheel. The key
is stored in the glove compartment,
center console storage, storage box, or
trunk. Register the key and lug nuts
with the lock manufacturer by filling
out the registration card and mailing it
in using the accompanying envelope. If
the key is lost, consult an Authorized
Mazda Dealer or use the lock
manufacturer’s order form to order a
new key.
Antitheft wheel lug nuts cannot be
installed on a steel wheel spare tire.
When installing a temporary spare tire,
use one of the original lug nuts in place
of the locking lug nut. The original lug
nuts are stored inside your Mazda.

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.

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

Tire Rotation
To equalize tread wear, rotate the tires
every 16,000 km (10,000 miles) at the
latest or sooner if irregular wear
develops. Mazda recommends to
rotate every 8,000 km (5,000 miles) to
help increase tire life and distribute
wear more evenly.
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

Inspect the tires 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 on 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 weakened if rotated from side
to side.
Replacing a Tire
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.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
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 load ing 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.
