qSnow Tires
Use snow tires on all four wheels
Don't 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.
Your vehicle is originally equipped with
all season radials designed to be used all
year around. In some extreme climates
you may find it necessary to replace them
with snow tires during the winter months
to further improve traction on snow and
ice covered roads.
WARNING
Use 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.
NOTE
If your vehicle is equipped with the tire
pressure monitoring system, the system
may not function correctly when using
tires with steel wire reinforcement in
the sidewalls (page 5-29).
qTire Chains
Check local regulations before using tire
chains.
CAUTION
lChains may scratch or chip
aluminum wheels. Install tire chains
on steel wheels only.
lChains may affect handling.
lDon't go faster than 50 km/h (30
mph) or the chain manufacturer's
recommended limit, whichever is
lower.
lDrive carefully and avoid bumps,
holes, and sharp turns.
lAvoid locked-wheel braking.
lDon't use chains on a temporary
spare tire; it may result in damage to
the vehicle and to the tire.
lDon't use chains on roads that are
free of snow or ice. The tires and
chains could be damaged.
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 front tires.
Don't use chains on the rear tires.
Use only genuine Mazda tire chains.
Please consult an Authorized Mazda
Dealer.

TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
CAUTION
lEach 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.
CAUTION
lYour 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.
lTo 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.

CAUTION
l(With limited slip differential)
When using the temporary spare tire
on the front 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).

6. Block the wheel diagonally opposite
the flat tire. 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 to hold
the tire in place.
qRemoving a Flat Tire
1. If your vehicle is equipped with a
wheel cover, pry off the wheel cover
with the beveled end of the lug wrench.
NOTE
Force the end of the lug wrench firmly
between wheel and cover, or removal
will be difficult.
CAUTION
There is a valve-stem mark inside the
wheel cover. When installing the wheel
cover, align this mark with the tire's
valve stem.
Damage could occur during installation
if the wheel cover is not properly
aligned.
2. Loosen the lug nuts by turning them
counterclockwise one turn each, but
don't remove any lug nuts until the tire
has been raised off the ground.

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.
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 your Mazda (page 10-8)
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 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
10-8).
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) when the tires are
cold. Maintain recommended pressures
for the best ride, 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
10-8).

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 8-37).
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 9-22.
qReplacing a Wheel
WARNING
Using a Wrong-Sized Wheel:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be affected, leading to loss of
control and an accident. Always use
wheels of the correct size on your
vehicle.
CAUTION
lA wrong-sized wheel may adversely
affect:

Tread Wear, Traction and Temperature Grades
Tread wear:The tread wear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100.
Traction:The traction grades, from highest to lowest are AA, A, B, and C. The grades
represent the tire's ability to stop on wet pavement as measured under controlled conditions
on specified government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Temperature:The temperature grades are A (the highest), B and C, representing the tire's
resistance to the generation of heat and its ability to dissipate heat when tested under
controlled conditions on a specified indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local governments may require true snow tires, those with very
deeply cut tread. These tires should only be used in pairs or placed on all four wheels.
Make sure you purchase snow tires that are the same size and construction type as the other
tires on your vehicle.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
lEXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-
MATCH TIRE DIAMETER TO RIM DIAMETER; NEVER EXCEED 40 psi (275 kPa)
