Tires
▼Tires
For reasons of proper performance,
safety, and better fuel economy, 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 9-8)
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.
▼ 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 9-8.
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
9-8).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not
release air from warm tires to adjust
the pressure.
Underinflation can cause reduced
fuel economy, uneven and
accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh
ride, uneven and accelerated tire
wear, and a greater possibility of
damage from road hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating, have it inspected.

▼Tire Rotation
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.
1. Forward
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 pressureImproper wheel alignmentOut-of-balance wheelSevere braking
After rotation, inflate all tire pressures
to specification on page 9-8 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
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.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

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 8-23.
▼Temporary Spare Tire
Inspect the temporary spare tire at
least monthly to make sure it is
properly
inflated and stored.
NOTE
The temporary spare tire condition
gradually deteriorates even if it has not
been used.
The temporary spare tire is easier to
handle because of its construction
which is lighter and smaller than a
conventional tire. This tire should be
used only for an emergency and only
for a short distance.
Use the temporary spare tire only until
the conventional tire is repaired, which
should be as soon as possible.
Refer to Tires on page 9-8.
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 6-32).
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 8-23.
▼ 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.

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.

CAUTION
If your Mazda is damaged and needs
metal parts repaired or replaced, make
sure the body shop applies
anti-corrosion materials to all parts,
both repaired and new. This will
prevent them from rusting.
▼Bright-Metal Maintenance
Use tar remover to remove road tar
and insects. Never do this with a
knife or similar tool.
To prevent corrosion on bright-metal
surfaces, apply wax or chrome
preservative and rub it to a high
luster.
During cold weather or in coastal
areas, cover bright-metal parts with a
coating of wax or preservative
heavier than usual.
It would also help
to coat them with noncorrosive
petroleum jelly or some other
protective compound.
CAUTION
Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or caustic
agents on chrome-plated or anodized
aluminum parts. This may result in
damage to the protective coating and
cause discoloration or paint
deterioration.
▼ Underbody Maintenance
Road chemicals and salt used for ice
and snow removal and solvents used
for dust control may collect on the
underbody. If not removed, they will
speed up rusting and deterioration of
such underbody parts as fuel lines,
frame, floor pan, and exhaust system,
even though these parts may be coated
with anti-corrosive material.
Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try
also to do this every month.
Pay special attention to these areas
because they easily hide mud and dirt.
It will do more harm than good to wet
down the road grime without
removing it.
The lower edges of doors, rocker
panels, and frame members have drain
holes that should not be clogged.
Water trapped there will cause rusting.
WARNING
Dry off brakes that have become wet
by driving slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to normal:
Driving with wet brakes is dangerous.
Increased stopping
distance or the
vehicle pulling to one side when
braking could result in a serious
accident. Light braking will indicate
whether the brakes have been
affected.
▼ Aluminum Wheel Maintenance*
A protective coating is provided over
the aluminum wheels. Special care is
needed to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels.

NOTE
Do not use a wire brush or any
abrasive cleaner, polishing
compound, or solvent on aluminum
wheels. They may damage the
coating.
Always use a sponge or soft cloth to
clean the wheels.
Rinse the wheels thoroughly with
lukewarm or cold water. Also, be
sure to clean the wheels after driving
on dusty or salted roads to help
prevent corrosion.
Avoid washing your vehicle in an
automatic car wash that uses
high-speed or hard brushes.
▼Plastic Part Maintenance
When cleaning the plastic lenses of
the lights, do not use gasoline,
kerosene,
rectified spirit, paint,
thinner, highly acidic detergents, or
strongly alkaline detergents.
Otherwise, these chemical agents
can discolor or damage the surfaces
resulting in a significant loss in
functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or
battery fluid, it could cause
discoloration, staining , or paint
peeling. Wipe off any such chemical
agents or fluids using a soft cloth
immediately.
High water temperature and high
water pressure car washers are
available depending on the type of
high pressure car washer device. If
the car washer nozzle is put too
close to the vehicle or aimed at one
area for an extended period of time,
it could deform plastic parts or
damage the paint.
Do not use wax containing
compounds (polish). Otherwise, it
could result in paint damage.
In addition, do not use an electrical
or air tool to apply wax. Otherwise,
the frictional heat generated could
result in deformation of plastic parts
or paint damage.

WARNING
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.
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 mat.
2.(Vehicles with sub-woofer)
Uncouple the sub-woofer
connector.
NOTE
Extra strength may be required to
uncouple the connector. Be sure to
squeeze the tab firmly.
3. (Vehicles with sub-woofer)
Turn the spare tire hold-down bolt
counterclockwise and remove the
sub-woofer and the spare tire.

2. Shift into Park (P) and turn off theengine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle and away from the vehicle
and traffic.
5. Remove any luggage, the jack, tools, 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.
▼Removing a Flat Tire
WARNING
When jacking-up a vehicle, always
shift the selector lever to P position,
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a flat tire without using
wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a
wheel cover, pry off the wheel
cover with the beveled end of the
jack lever.
NOTE
Force the end of the jack lever
firmly between wheel and cover, or
removal will be difficult.
