2017 MAZDA MX5 MIATA tire size

3 –54 Before Driving
Driving Tips 
Drive slowly. Braking performance
can be adversely affected if snow or
ice adheres to the brake components. If
this situation occurs, drive the vehicle
slowly, releasing the accelerator pedal
and lightly applying the brakes several
times until the brake performance
returns to normal.
Snow TiresUse snow tires on all four wheels
Do not go faster than 120 km/h (75 mph)
while driving with snow tires. Inflate snow
tires 30 kPa (0.3 kgf/cm 2
, 4.3 psi) more
than recommended on the tire pressure
label (driver's door frame), but never
more than the maximum cold-tire pressure
shown on the tires.
The vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.
WARNINGUse only the same size and type tires
(snow, radial, or non-radial) on all four
wheels:
Using tires different in size or type is
dangerous. Your vehicle's handling
could be greatly affected and result in
an accident.
CAUTION Check local regulations before using
studded tires. Tire Chains Check local regulations before using tire
chains.
CAUTION 
Chains may affect handling. 
Do not go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is lower. 
Drive carefully and avoid bumps, holes,
and sharp turns. 
Avoid locked-wheel braking. 
Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged. 
Chains may scratch or chip aluminum
wheels.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using tire
chains.
Install the chains on the rear tires only.
Do not use chains on the front tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. Secure the chains on the rear tires as
tightly as possible.
Always follow the chain manufacturer's
instructions.
2. Retighten the chains after driving
1/2—1 km (1/4—1/2 mile).

4 –67 When Driving
ABS/TCS/DSC
Dynamic Stability
Control (DSC) The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such
as ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.
Refer to ABS (page 4-65 ) and TCS
(page 4-66 ).
DSC operation is possible at speeds
greater than 20 km/h (12 mph).
The warning light turns on when the
system has a malfunction.
Refer to Warning Indication/Warning
Lights on page 4-26 .
WARNING Do not rely on the Dynamic Stability
Control as a substitute for safe driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and
reckless driving, excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident. CAUTION 
The DSC may not operate correctly
unless the following are observed: 
Use tires of the correct size specified
for your Mazda on all four wheels. 
Use tires of the same manufacturer,
brand and tread pattern on all four
wheels. 
Do not mix worn tires. 
The DSC may not operate correctly when
tire chains are used or a temporary spare
tire is installed because the tire diameter
changes.
TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched
ON. If the TCS or DSC is operating, the
indicator light flashes.
If the light stays on, the TCS, DSC
or the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

4 –106 When Driving
Tire Pressure Monitoring System
CAUTION 
Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pressure telltale when one or more of your tires
is significantly under-inflated. Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when
the system is not operating properly.
The TPMS malfunction indicator is combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for approximately one minute and then
remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly. 
To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously register a rapid tire deflation or blow out.

4 –107 When Driving
Tire Pressure Monitoring SystemNOTE
Because this system detects slight changes in tire conditions, the timing of the warning may
be faster or slower in the following cases: 
The size, manufacturer, or the type of tires is different from the specification. 
The size, manufacturer, or the type of a tire is different from the others, or the level of tire
wear is excessively different between them. 
A run-flat tire, studless tire, snow tire, or tire chains are used. 
An emergency tire is used (The tire pressure monitoring system warning light may flash
and then continue illuminating). 
A tire is repaired using the emergency flat tire repair kit. 
The tire pressure is excessively higher than the specified pressure, or the tire pressure is
suddenly lowered for some reason such as a tire burst during driving. 
The vehicle speed is lower than about 15 km/h (9.3 mph) (including when the vehicle is
stopped), or the drive period is shorter than 5 minutes. 
The vehicle is driven on an extremely rough road or a slippery, icy road. 
Hard steering and rapid acceleration/deceleration are repeated such as during aggressive
driving on a winding road. 
Load on the vehicle is applied to a tire such as by loading heavy luggage to one side of
the vehicle. 
System initialization has not been implemented with the specifie d tire pressure.

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.

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.

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 

7 –16 If Trouble Arises
Flat Tire
Changing a TireWARNINGBe sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure someone.
No person should place any portion
of their body under a vehicle that is
supported by a jack.
Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in
a vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.
NOTE
Make sure the jack is well lubricated
before using it.
1. Park on a hard, level surface off the
right-of-way and firmly set the parking
brake.
2. Put a vehicle with an automatic
transmission in Park (P), a manual
transmission in Reverse (R) or 1, and
turn off the engine.
3. Turn on the hazard warning flasher.
4. Have everyone get out of the vehicle
and away from the vehicle and traffic.
5. Remove the jack and tool (page
7-3 ). 6. Block the wheel diagonally opposite
the tire to be changed. 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 Tire 1. Loosen the lug nuts by turning them
counterclockwise one turn each, but do
not remove any lug nuts until the tire
has been raised off the ground.

2. Place the jack on the ground.
