CAUTION
lTo avoid damage to the temporary
spare or to the vehicle, observe the
following precautions:
lDon't exceed 80 km/h (50 mph).lAvoid driving over obstacles.
Also, don't drive through an
automatic car wash. This tire's
diameter is smaller than a
conventional tire's, so the ground
clearance is reduced about 25 mm
(1 in).
lDon't use a tire chain on this tire
because it won't fit properly.
lDon't use your temporary spare
on any other vehicle; it has been
designed only for your Mazda.
lUse only one temporary spare tire
on your vehicle at the same time.
(With limited slip differential)
When using the temporary spare tire on
the rear axle, replace it with a standard
tire as soon as possible. The size
difference between the spare and the
standard tire will cause the limited slip
differential to malfunction.
NOTE
(With Tire Pressure Monitoring
System)
A tire pressure sensor is not installed to
the temporary spare tire. The warning
light will flash continuously while the
temporary spare tire is being used (page
5-27).

qLocking Lug Nuts
If your vehicle has optional antitheft
wheel lug nuts, one on each wheel will
lock the tires and you must use a special
key to unlock them. This key is attached
to the lug wrench and is stored with the
spare tire. Register them with the lock
manufacturer by filling out the card
provided in the glove box 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.

Tires
For 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.
Use all radial, all bias-belted, or all
bias-type tires.
Using Wrong-Sized Tires:
Using any other tire size than what is
specified for your Mazda (page 10-6)
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 your
Mazda.
qTire Inflation Pressure
WARNING
Incorrect Tire Inflation:
Overinflation or underinflation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in
a serious accident. Always inflate the
tires to the correct pressure (page
10-6).The Tire Pressure Monitoring System
í
does not alleviate the need to check the
tire condition every day, including
whether the tires all look inflated properly.
Inspect all tire pressure monthly
(including the spare
í) when the tires are
cold. Maintain recommended pressures
for the best ride, top handling, and
minimum tire wear.
When checking the tire pressures, use of a
digital tire pressure gauge is
recommended.
Refer to the specification charts (page
10-6).

NOTE
lAlways check tire pressure when
tires are cold.
lWarm tires normally exceed
recommended pressures. Don't
release air from warm tires to adjust
the pressure.
lUnderinflation 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.
lOverinflation 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.
qTire Rotation
To equalize tread wear, rotate the tires if
irregular wear develops. According to the
scheduled maintenance charts.Refer to
Scheduled Maintenance on page 8-3.
During rotation, inspect them for correct
balance.
NOTE
Because your vehicle is not equipped
with a spare tire, you cannot do a tire
rotation safely with the jack that comes
with your vehicle. Have an Authorized
Mazda Dealer perform tire rotation.
Forward
Also, inspect them for uneven wear and
damage. Abnormal wear is usually caused
by one or a combination of the following:
lIncorrect tire pressure
lImproper wheel alignment
lOut-of-balance wheel
lSevere braking
After rotation, inflate all tire pressures to
specification (page 10-6) 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 weakened if rotated from side to
side.

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. You should replace
the spare tire when you replace the
other road tires due to the aging of the
spare tire. Regarding the manufacturing
week and year is indicated with 4 digit.
Refer to The tire labeling on page 9-18.
qTemporary Spare Tire
Your Mazda is not equipped with a spare
tire. If you require a spare tire, consult an
Authorized Mazda Dealer.
Inspect the temporary spare tire at least
monthly to make sure it's properly inflated
and stored.
NOTE
The temporary spare tire condition
gradually deteriorates even if it has not
been used.
The temporary spare tire is easier to
handle because of its construction. It is
lighter and smaller than a conventional
tire and should be used only for an
emergency and only for a short distance.
Use the temporary only until the
conventional tire is repaired, which should
be as soon as possible.
Maintain its pressure at 420 kPa (4.2
kgf/cm
2or bar, 60 psi).
CAUTION
lDon't use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly fit and could damage both
tire and rim.
lThe temporary spare tire has a tread
life of less than 5,000 km (3,000
miles). The tread life may be shorter
depending on driving conditions.
lThe temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type of
temporary spare (page 8-29).

WARNING
Tire Under-Inflation:
Driving your vehicle with under-inflated tires is dangerous.
Under-inflation is the most common cause of failures in any kind of tire and may
result in severe cracking, tread separation or“blowout”, with unexpected loss of
vehicle control and increased risk of injury. Under-inflation increases sidewall flexing
and rolling resistance, resulting in heat buildup and internal damage to the tire. It
results in unnecessary tire stress, irregular wear, loss of control and accidents. A tire
can lose up to half of its air pressure and not appear to be flat!
It is impossible to determine whether or not tires are properly inflated just by looking
at them.
Always check the tire inflation pressures on a regular basis according to the
recommended tire inflation pressure on the tire label and in conjunction with the
information in this owner's manual.
qChecking Tire Pressure
1. When you check the air pressure, make sure the tires are cold―meaning they are not
hot from driving even a mile.
2. Remove the cap from the valve on one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by pushing on the metal stem in the center of the
valve. Then recheck the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher inflation pressure.
8. Visually inspect the tires to make sure there are no nails or other objects embedded that
could poke a hole in the tire and cause an air leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or other
irregularities.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
qTire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specified on the vehicle tire information placard or tire label for optimum service.
qTire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) or sooner if irregular
wear develops. During rotation, inspect them for correct balance.
Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
lIncorrect tire pressure
lImproper wheel alignment
lOut-of-balance wheel
lSevere braking
After rotation, inflate all tire pressures to specification (page 10-6) and inspect the lug nuts
for tightness.
