▼Tire In
flation Pressure
WARNING
Always in flate the tires to the correct
pressure:
Overin flation or underin flation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-10.
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, handling ,
and minimum tire wear.
Refer to the specification charts (page
9-10).
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.
Underin flation 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.
Overin flation 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 in flating, 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 periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tire rotation interval.
During rotation, inspect them for
correct balance.

1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

free from dirt or rust.
Make sure the screw thread is
adequately lubricated.
▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WARNING
Do not install the temporary spare tire
on the front wheels (driving wheels):
Driving with the temporary spare tire
on one of the front driving wheels is
dangerous. Handling will be a
ffected.
You could lose control of the vehicle,
especially on ice or snow bound roads,
and have an accident. Move a regular
tire to the front wheel and install the
temporary spare tire to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease
compared to when using only the
conventional tire. Drive carefully.
 To avoid damage to the temporary
spare tire or to the vehicle, observe
the following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also,
do not drive through an automatic
car wash. This tire's diameter is
smaller than a conventional tire, so
the ground clearance is reduced.
 Do not use a tire chain on this tire
because it will not
fit properly.
 Do not use your temporary spare
tire on any other vehicle, it has
been designed only for your
Mazda.
 Use only one temporary spare tire
on your vehicle at the same time.

wood blocks of su fficient size if
possible to hold the tire in place.
▼ Removing a Flat Tire
WARNING
When jacking-up a vehicle, always
shift the shift lever to 1st or R position
(manual transmission vehicle) or shift
the selector lever to P position
(automatic transmission vehicle),
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a
flat tire without using
wheel blocks is dangerous because the
vehicle may move and fall o ff the jack
even with the shift lever in 1st or R
position, or the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a wheel cover, pry off the wheel
cover with the beveled end of the

Tire Maintenance
▼Tire Maintenance
Improper or inadequate vehicle
maintenance can cause tires to wear
abnormally. Here are some important
maintenance points:
▼Tire
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 speci
fied on the vehicle
tire information placard or tire label for
optimum service.
▼ Tire Rotation
To equalize tread wear, rotate the tires
every 16,000 km (10,000 miles) at the
latest or sooner if irregular wear
develops. Mazda recommends to
rotate every 8,000 km (5,000 miles) to
help increase tire life and distribute
wear more evenly.
1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

Inspect the tires 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, in flate all tire pressures
to speci fication on page 9-10 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.
▼ 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.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
1. New tread
2. Worn tread
3. Tread wear indicator

You should replace the tire before the
band crosses the entire tread.
