2016 MAZDA MX5 MIATA inflation pressure

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
WARNING
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.
(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 4-96.
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)
Don't 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 aren't 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.

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/cm2, 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/cm2, 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.

4. Turn the lug wrench counterclockwise
and lower the vehicle. Use the lug
wrench to tighten the nuts in the order
shown.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.
Nut tightening torque
N·m (kgf·m, ft·lbf) 108—147
(12—14, 80—108)
WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
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 configuration: Because the wheel studs and lug 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 tire blocks and store the
tools and jack.
6. Check the inflation pressure. Refer to
Tires on page 9-8.
NOTE
(With tire pressure monitoring system)
Do not press the tire pressure monitoring
system set switch after installing the spare
tire. The switch is only to be pressed after
installing the repaired flat tire or installing
a replacement tire (page 4-16).

(Illuminate)Tire Pressure
Monitoring System Warning Light
*
When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), tire pressure is too low in one or
more tires.
WARNING
If the tire pressure monitoring system warning light illuminates or flashes,
or the tire pressure warning beep
sound is heard, decrease vehicle
speed immediately and avoid sudden
maneuvering and braking: If the tire pressure monitoring system
warning light illuminates or flashes, or
the tire pressure warning beep sound
is heard, it is dangerous to drive the
vehicle at high speeds, or perform
sudden maneuvering or braking.
Vehicle drivability could worsen and
result in an accident.
To determine if you have a slow leak or
a flat, pull over to a safe position where
you can check the visual condition
of the tire and determine if you have
enough air to proceed to a place where
air may be added and the system
monitored again by an Authorized
Mazda Dealer or a tire repair station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken
care of as soon as possible before it
develops into a more serious situation
that could lead to tire failure and a
dangerous accident. Inspect the tires and adjust to the specified
inflation pressure (page
6-41).
NOTE
Perform tire pressure adjustment when
the tires are cold. Tire pressure will vary
according to the tire temperature, therefore
let the vehicle stand for 1 hour or only
drive it 1.6 km (1 mile) or less before
adjusting the tire pressures. When pressure
is adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may
turn on after the tires cool and pressure
drops below specification.
Also, an illuminated TPMS warning
light, resulting from the tire air pressure
dropping due to cold ambient temperature
will remain illuminated even if the ambient
temperature rises. In this case, it will also
be necessary to adjust the tire air pressures.
If the TPMS warning light illuminates due
to a drop in tire air pressure, make sure to
check and adjust the tire air pressures.
Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too
soft over time or you have a flat. However,
when you find one low tire in a set of four-
that is an indication of trouble; you should
have someone drive the vehicle slowly
forward so you can inspect any low tire for
cuts and any metal objects sticking through
tread or sidewall. Put a few drops of
water in the valve stem to see if it bubbles
indicating a bad valve. Leaks need to be
addressed by more than simply reinflating
the tire as leaks are dangerous — take it to
an Authorized Mazda Dealer.
