Ty r e I nÀ ation Pressure
WARNING
Always inÀ ate the tyres to the correct
pressure:
OverinÀ ation or underinÀ ation of tyres
is dangerous. Adverse handling or
unexpected tyre failure could result in
a serious accident.
Refer to Tyres on page 9-8 .
Use only a Mazda-genuine tyre valve
cap:
Use of a non-genuine part is dangerous
as the correct tyre air pressure cannot
be maintained if the tyre valve becomes
damaged. If the vehicle is driven under
this condition, the tyre air pressure
will decrease which could result in a
serious accident. Do not use any part
for the tyre valve cap that is not a
Mazda-genuine part.
Inspect all tyre pressures monthly when
the tyres are cold. Maintain recommended
pressures for the best ride, handling, and
minimum tyre wear.
Refer to the speci¿ cation charts (page
9-8 ).
(With tyre pressure monitoring system)
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-143 .
NOTE

 Always check tyre pressure when
tyres are cold.
  Warm tyres normally exceed
recommended pressures. Do not
release air from warm tyres to adjust
the pressure.
  UnderinÀ ation can cause reduced
fuel economy, uneven and
accelerated tyre wear, and poor
sealing of the tyre bead, which
will deform the wheel and cause
separation of tyre from rim.
  OverinÀ ation can produce a harsh
ride, uneven and accelerated tyre
wear, and a greater possibility of
damage from road hazards.
 Keep your tyre pressure at the correct
levels. If one frequently needs
inÀ ating, have it inspected.
Tyre Rotation
WARNING
Rotate tyres periodically:
Irregular tyre wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tyres every 10,000
km (6,250 miles), or sooner if irregular
wear develops.
During rotation, inspect them for correct
balance.

Maintenance and Care
Owner Maintenance
NOTE
Because your vehicle is not equipped
with a spare tyre, you cannot do a tyre
rotation safely with the jack that comes
with your vehicle. Have an expert
repairer, we recommend an Authorised
Mazda Repairer perform tyre rotation.
Do not include (TEMPORARY USE ONLY)
spare tyre in rotation.Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
 


 Incorrect tyre pressure



 Improper wheel alignment



 Out-of-balance wheel



 Severe braking
After rotation, inÀ ate all tyre pressures to
speci¿ cation (page 9-8 ) and inspect the
wheel nuts for tightness.
(With tyre pressure monitoring system)
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-143 .
CAUTION
Rotate unidirectional tyres and radial
tyres that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tyre performance
will be reduced if rotated from side to
side.
(With limited-slip differential)
Do not use the following:
 
 Tyres not of the designated size 
 Tyres of different sizes or types at the
same time
  Tyres not suf¿ ciently inÀ ated
If these instructions are not followed,
the rotation of the left and right wheels
will be different and will thus apply
a constant load on the limited-slip
differential.
This will cause a malfunction.
Replacing a Tyre
WARNING
Always use tyres that are in good
condition:
Driving with worn tyres is dangerous.
Reduced braking, steering, and traction
could result in an accident.
Replace all four tyres at the same time:
Replacing just one tyre is dangerous.
It could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tyres at the
same time.

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:
 
 Tyre ¿ t 
 Wheel and bearing life 
 Ground clearance 
 Snow-chain clearance 
 Speedometer calibration 
 Headlight aim 
 Bumper height

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 expert
repairer, we recommend an
Authorised Mazda Repairer.
Proper tyre balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tyres can cause
vibration and uneven wear, such as
cupping and À at spots.

Either run-À at tyres or conventional tyres
are equipped on your Mazda depending on
the speci¿ cation, therefore the procedure
for repairing a À at tyre differs depending
on the type of tyre. Before driving, make
sure which type of tyre is equipped on
your Mazda. If you cannot identify your
tyre type, consult an expert repairer,
we recommend an Authorised Mazda
Repairer.
How to Identify Your Tyre Type

WARNING
Have the tyres checked or perform the
appropriate repair as soon as possible
by an expert repairer, we recommend
an Authorised Mazda Repairer:
When the À at tyre warning light
illuminates or the tyre pressure
warning beep sound is heard, it is
dangerous to drive the vehicle at
high speeds, or perform sudden
manoeuvring or braking. Vehicle
drivability could worsen and result in
an accident.
When the À at tyre warning light
illuminates or the tyre pressure
warning beep sound is heard, decrease
vehicle speed immediately and avoid
sudden manoeuvring and braking.
If a run-À at tyre is punctured, the FLAT
TIRE warning light illuminates in the
instrument cluster, and a beep sound is
heard for about 30 seconds.
NOTE
Until the À at tyre is changed, the beep
sound is heard for about 30 seconds
every time the ignition is switched ON.

correct tyre inÀ ation pressure.

 Do not operate the air compressor for
a continuous 10 minutes or longer
because using it for long periods
could cause a malfunction.
  If the tyre inÀ ation pressure does
not increase, repair of the tyre is not
possible. If the tyre does not reach
the speci¿ ed tyre inÀ ation pressure
within 10 minutes, it may have
received extensive damage. In this
case, the repair using the emergency
À at tyre repair kit was not successful.
Contact an expert repairer, we
recommend an Authorised Mazda
Repairer.
  If the tyre has been over-inÀ ated,
loosen the screw cap on the air
compressor and bleed some of the air

80 km/h (50 mph) or less. If the vehicle
is driven at a speed of 80 km/h (50 mph)
or more, the vehicle may vibrate.
NOTE
(With tyre pressure monitoring
system)
If the tyre is not properly inÀ ated, the
tyre pressure monitoring system warning
light will illuminate.
24. After driving the vehicle for about 10
minutes or 5 km (3 miles), connect the
air compressor to the tyre using Step
17 of the procedure, and check the
tyre inÀ ation pressure using the tyre
pressure gauge on the air compressor. If
the tyre inÀ ation pressure is lower than
the speci¿ ed tyre inÀ ation pressure,
turn the air compressor on and wait
until it reaches the speci¿ ed tyre
inÀ ation pressure.
WARNING
If the tyre inÀ ation pressure has
decreased below 130 kPa (1.3 kgf/cm 2
or bar, 18.9 psi), stop driving and
contact an expert repairer, we
recommend an Authorised Mazda
Repairer:
The repair using the emergency À at
tyre repair kit was not successful.

If Trouble Arises
Flat Tyre
WARNING
Always securely and correctly tighten
the wheel nuts:
Improperly or loosely tightened wheel
nuts are dangerous. The wheel could
wobble or come off. This could result
in loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same con¿ guration:
Because the wheel studs and wheel
nuts on your Mazda have metric
threads, using a non-metric nut is
dangerous. On a metric stud, it would
not secure the wheel and would
damage the stud, which could cause the
wheel to slip off and cause an accident.
5. Remove the tyre blocks and store the
tools and jack.
6. Check the inÀ ation pressure. Refer to
Tyres on page 9-8 .
NOTE
(With tyre pressure monitoring
system)
Do not press the tyre pressure
monitoring system set switch after
installing the spare tyre. The switch
is only to be pressed after installing
the repaired À at tyre or installing a
replacement tyre (page 4-42 ).
WARNING
Do not drive with any tyres that have
incorrect air pressure:
Driving on tyres with incorrect air
pressure is dangerous. Tyres with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tyres' air
pressure, check the spare tyre, too.
NOTE
To prevent the jack and tool from
rattling, store them properly.
