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.
WA R N I N G
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 9-7) 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
WA R N I N G
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 9-7.
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
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handl
ing, and minimum tire
wear.
Refer to the specification charts (page
9-7).
NOTE
Cold inflation pressure
The cold inflation pressure is the
pressure measured under ambient
temperatures before the vehicle is
driven.
Maximum inflation pressure
The maximum inflation pressure is the
upper limit of the cold inflation pressure
designated by the tire manufacturer.
Recommended inflation pressure
The recommended inflation pressure is
the cold inflation pressure necessary for
maintaining the performance of your
Mazda.
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.
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 frequen tly 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.
Maintenance and Care

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, inflat e all tire pressures to
specification (page 9-7) 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.
▼ Replacing a Tire
WA R N I N G
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.
New tread Tread wear indicator
Worn tread
You should replace the tire before the band
crosses the entire tread.

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. 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 8-25.
▼Temporary Spare Tire
Inspect the temporary spare tire at least
monthly to make sure it is 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 which is
lighter and smaller than a conventional
tire. This tire should be used only for an
emergency and only for a short distance.

Use the temporary spar
e tire only until the
conventional tire is repaired, which should
be as soon as possible.
Refer to Tires on page 9-7.

CAUTION
 Do not 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.
The 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.
 The 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 6-37).
