2021 MAZDA MODEL CX-30 spare tire

CAUTION
Do not use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly
fit and could damage both
tire and rim.
 The temporary spare tire has a tread
life of less than 5,000 km (3,000
miles). The tread life may be shorter
depending on driving conditions.
 The temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type of
temporary spare (page 6-33).
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.
▼ Replacing a Wheel
WARNING
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
NOTE
When replacing a wheel, make sure
the new one is the same as the
original factory wheel in diameter,
rim width, and
offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

could indicate a flat tire.
Steering becomes
difficult.The vehicle begins to vibrate
excessively.
The vehicle pulls in one direction.
If you have a flat tire, drive slowly to a
level spot that is well off the road and
out of the way of traffic to change the
tire.
Stopping in traffic or on the shoulder
of a busy road is dangerous.
WARNING
Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure someone.
No person should place any portion of
their body under a vehicle that is
supported by a jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in a
vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.
NOTE
Make sure the jack is well lubricated
before using it.

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
