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 8-26.
▼Replacing a Wheel
WA R N I N G
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.

To secure the jack
1. Insert the wing bolt into the jack withthe jack screw pointing back and turn
the wing bolt clockwise to temporarily
tighten it.
2. Tighten the jack screw clockwise.
Wing boltJack screw
3. Turn the wing bolt completely tosecure the jack.
NOTE
If the jack is not completely secured, it
could rattle while driving. Make sure
the jack screw is sufficiently tightened.
Maintenance
•Always keep the jack clean.
•Make sure the moving parts are kept
free from dirt or rust.
•Make sure the screw thread is
adequately lubricated.
▼ Spare Tire
Your Mazda has a temporary 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 fo
r long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front 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 front
wheel and install the temporary spare tire
to the rear.

Changing a Flat Tire
NOTE
If the following occurs while driving, it
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.
WA R N I N G
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.
1. Park on a hard, level surface off the right-of-way and firml y set the parking
brake.
2. Shift into Park (P) and turn off the engine.
3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle and away from the vehicle and traffic.
5. Remove the jack, tool, and spare tire
(page 7-3).
6. Block the wheel diagonally opposite
the flat tire. When blocking a wheel,
place a tire block both in front and
behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.

WARNING
Do not jack up the vehicle higher than
is necessary:
Jacking up the vehicle higher than is
necessary is dangerous as it could
destabilize the vehicle resulting in an
accident.
Do not start the engine or shake the
vehicle while it is jacked up:
Starting the engine or shaking the
vehicle while it is jacked up is
dangerous as it could cause the vehicle
to fall off the jack resulting in an
accident.
Never go under the vehicle while it is
jacked up:
Going under the vehicle while it is
jacked up is dangerous as it could result
in death or serious injury if the vehicle
were to fall off the jack.
8. Remove the lug nuts by turning them counterclockwise; then remove the
wheel and center cap.
▼Locking Lug Nuts
If your vehicle has Mazda optional
antitheft wheel lug nuts, each wheel will
have one locking lug nut that locks the
wheel and tire, and you must use a special
key to unlock the locking lug nut. This key
is stored in the glove compartment.
Register the key and l
ug nuts with the lock
manufacturer by filling out the card
provided in the glove compartment and
mailing it in the accompanying envelope.
If you lose this key, consult an Authorized
Mazda Dealer or use the lock
manufacturer's order form, which is with
the registration card.
Accessory wheel locks cannot be used on
steel wheels. This includes situations when
the spare tire is installed. If the spare tire is
installed, one of th e original lug nuts
(which should still be in the vehicle) must
be installed in place of the wheel lock.
Special key
Antitheft lug nut
To remove an antitheft lug nut
1. Obtain the special key for the antitheft
lug nut.
2. Place the special key on top of the
antitheft lug nut, and be sure to hold
the key square to it. If you hold the key
at an angle, you may damage both key
and nut. Do not use a power impact
wrench.
3. Place the lug wrench on top of the key and apply pressure. Turn the wrench
counterclockwise.

▼Mounting the Spare Tire
NOTE
The number and shape of the flat tire belt
differ depending on the vehicle
specification.
Belt clips
•The flat tire belts with the clips are for
securing a flat tire.
•The flat tire belts without the clips are
for securing the sub-woofer.
1. Remove dirt and grime from the
mounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.
WA R N I N G
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to w ear abnormally. Here are
some important maintenance points:
▼ Tire Inflation Pressure
Inspect all tire pressu
re monthly (including the spare) when th e tires are cold. Maintain
recommended pressures for the best ride, top handling, and mini mum tire wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
▼Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500
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 d istribute wear more evenly.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
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 (pa ge 9-9) 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.
