2018 MAZDA MODEL MX-5 tire pressure

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
WA R N I N G
Rotate 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 (TEMPORARY 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.
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.

▼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.

10. Install the bottle to the air compressorand press it in until the left and right
tabs are engaged securely.

11. Insert the air compressor plug into theaccessory socket inside the vehicle and
switch the ignition to ACC.
Refer to Accessory Sockets on page
5-140.
Compressor
Compressor plug
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/ c m
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.
NOTE
Check the tire inflation pressure
label driver's door frame for the
correct tire inflation 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 tire inflation pressure does not
increase, repair of the tire is not
possible. If the tire does not reach
the specified tire inflation pressure
within 10 minutes, it may have
received extensive damage. In this
case, the repair using the emergency
flat tire repair kit was not successful.
Contact an Authorized Mazda
Dealer.
13. Adhere the speed restriction sticker to
an area where it can be viewed easily
by the driver.
14. Adhere the repaired tire sticker to thewheel of the flat tire.
WA R N I N G
Do not adhere the speed restriction
sticker to the padded area on the
steering wheel:
Adhering the speed restriction sticker to
the padded area on the steering wheel
is dangerous because the air bag may
not operate (deploy) normally resulting
in serious injury. In addition, do not
adhere the sticker to areas where
warning lights or the speedometer
cannot be viewed.
15. When the tire inflates to the specified tire inflation pre ssure, turn the air
compressor switch off, turn the sleeve
of the injection hose to the left, and
pull it out of the tire valve.
16. Remove the air compressor hose from
the injection valve of the bottle. After
that, install the injection hose to the
injection valve of t he bottle to prevent
leakage of any remaining sealant.
CAUTION
The remaining sealant in the hose may
spray out when the hose is removed.
Remove the hose carefully because you
may not be able to remove the sealant
contacting clothing or other objects.

17. Install the tire valve cap.
18. Put the emergency flat tire repair kitinto the trunk.
19. Start driving immediately to spread the sealant in the tire.
CAUTION
Carefully drive the vehicle at a speed of
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
If the tire is not properly inflated, the
tire pressure monitoring system
warning light will illuminate (page
4-26).
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 th e 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
inflation pressure does not decrease.
Carefully drive the vehicle to the
nearest Authorized Mazda Dealer
immediately and have the flat tire
replaced. Replacement with a new tire
is recommended. If the tire is to be
repaired or reused, consult an
Authorized Mazda Dealer.
NOTE
If an emergency flat tire repair has
been performed using the emergency
flat tire repair kit, Mazda
recommends that the tire be replaced
with a new one as soon as possible.
If the tire is to be repaired or reused,
consult an Authorized Mazda
Dealer.
The wheel can be reused if the
sealant adhering to it is removed.
However, replace the valve with a
new one.

▼Locking Lug Nuts*
If your vehicle has Mazda optional
antitheft wheel lu
g nuts, one on each
wheel will lock the tires and you must use
a special key to unlock them. This key will
attach to the lug wrench. Register them
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 the 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.
