6 –41 Maintenance and Care
Owner Maintenance
TiresFor 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 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 ).
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 .
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.
MX-5_8FR4-EA-16J_Edition1.indb 41 2016/08/11 20:29:46

6 –42 Maintenance and Care
Owner Maintenance 
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
WARNINGRotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking, rotate the tires every 12,000
km (7,500 miles). However Mazda
recommends to rotate every 8,000 km
(5,000 miles) to help increase tire life
and distribute wear more evenly.
Refer to Scheduled Maintenance on
page 6-4 .
During rotation, inspect them for correct
balance.
Do not include (TEMPORAR Y USE ONLY)
spare tire 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 tire pressure 
Improper wheel alignment 
Out-of-balance wheel 
Severe braking
After rotation, inflate all tire pressures to
specification (page 9-8 ) and inspect the
lug nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 .
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.
(With limited-slip differential)
Do not use the following: 
Tires not of the designated size 
Tires of different sizes or types at
the same time 
Tires not sufficiently inflated
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.

6 –43 Maintenance and Care
Owner Maintenance
*Some models. 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.
Ne w tread Tread wear indicator
Worn tread
You should replace the tire before the band
crosses the entire tread.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108 . 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. 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 

CAUTION When inserting the air compressor
plug into or removing it from the
accessory socket, make sure that the
air compressor switch is off. When
turning the air compressor on/off, use
the air compressor switch. 12. The sealant is injected into the tire
when the air compressor is switched
on. After the sealant is injected
completely, wait until the tire inflation
pressure increases to the specified tire
inflation pressure.
NOTE
The inflation pressure may increase to
about 300 kPa (3.1 kgf/cm 2
, 3 bar, 43.5
psi) temporarily to inject the sealant
through the valve. Normally, the inflation
pressure decreases gradually and it
reaches the actual inflation pressure after
about 30 seconds.
WARNING Never use the air compressor above 300
kPa (3.1 kgf/cm 2
, 3 bar, 43.5 psi):
Using the air compressor at an
inflation pressure above 300 kPa (3.1
kgf/cm 2
, 3 bar, 43.5 psi) continuously
is dangerous. If the air compressor
overheats, hot air will be exhausted
and you could get burned.

mph) or more, the vehicle may vibrate.
NOTE
(With Tire Pressure Monitoring System)
If the tire is not properly inflated, the tire
pressure monitoring system warning light
will illuminate (page 4-18 ). 20. After driving the vehicle for about 10
minutes or 5 km (3 miles), connect the
air compressor to the tire using Step
9 of the procedure, and check the tire
inflation pressure using the tire pressure
gauge on the air compressor. If the
tire inflation pressure is lower than the
specified tire inflation pressure, turn
the air compressor on and wait until
it reaches the specified tire inflation
pressure.
WARNING If the tire inflation pressure has
decreased below 130 kPa (1.3 kgf/cm 2
or
bar, 18.9 psi), stop driving and contact
an Authorized Mazda Dealer:
The repair using the emergency flat tire
repair kit was not successful.
If you see a decrease in the tire inflation
pressure, even if Steps 9 to 20 of the
procedure are performed repeatedly,
stop driving:
Contact an Authorized Mazda Dealer.
CAUTION Before checking the tire inflation
pressure using the tire pressure gauge,
turn the air compressor switch off.
21. The emergency flat tire repair is
completed successfully if the tire
