2012 MAZDA MODEL 3 5-DOOR tires

Black plate (426,1)
CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't 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.
q 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.
CAUTION
(With Tire Pressure Monitoring
System)
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged. NOTE
(With Tire Pressure Monitoring System)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-35.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-35.
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 9-24.

qTemporary Spare Tire
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 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 spare tire 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
Ø 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.
Ø 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.
Ø 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 8-40). 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 9-24.
q
Replacing a Wheel

Ø (With Tire Pressure Monitoring
System)
ØWhen replacing/repairing the
tires or wheels or both, have the
work done by an Authorized
Mazda Dealer, or the tire
pressure sensors may be
damaged.
ØThe wheels equipped on your
Mazda are specially designed
for installation of the tire
pressure sensors. Do not use
non-genuine wheels, otherwise
it may not be possible to install
the tire pressure sensors.
NOTE
Be sure to install the tire pressure sensors
whenever tires or wheels are replaced. Refer to
Tires and Wheels on page 5-35.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset
(inset/outset). Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

qWater Marks
Occurrence
Rain, fog, dew, and even tap water can
contain harmful minerals such as salt and
lime. If moisture containing these
minerals settles on the vehicle and
evaporates, the minerals will concentrate
and harden to form white rings. The rings
can damage your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These
steps should be taken immediately after
you find water marks on your vehicle's
finish.
qPaint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel. NOTE
lThe paint chipping zone varies with the
speed of the vehicle. For example, when
traveling at 90 km/h (56 mph), the paint
chipping zone is 50 m (164 ft).
lIn low temperatures a vehicle's finish
hardens. This increases the chance of paint
chipping.
lChipped paint can lead to rust forming on
your Mazda. Before this happens, repair the
damage by using Mazda touch-up paint
according to the instructions in this section.
Failure to repair the affected area could
lead to serious rusting and expensive
repairs.

WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal:Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
qAluminum Wheel Maintenanceí
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels. NOTE
lDo not use a wire brush or any abrasive
cleaner, polishing compound, or solvent on
aluminum wheels. They may damage the
coating.
lAlways use a sponge or soft cloth to clean
the wheels.
Rinse the wheels thoroughly with lukewarm
or cold water. Also, be sure to clean the
wheels after driving on dusty or salted
roads to help prevent corrosion.
lAvoid washing your vehicle in an automatic
car wash that uses high-speed or hard
brushes.
lIf your aluminum wheels lose luster, wax
the wheels.
(With Tire Pressure Monitoring System)
Check special requirements for Tire Pressure
Monitoring System.
Refer to Tires and Wheels on page 5-35.
q Plastic Part Maintenance
lWhen cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
lIf plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.

Uniform Tire Quality Grading System (UTQGS)
This information relates to the tire grading system developed by the U.S. National
Highway Traffic Safety Administration for grading tires by tread wear, traction, and
temperature performance.
qTread 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-a-half times as well on the government
course as a tire graded 100.
The relative performance of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm because of variations in driving habits, service
practices and differences in road characteristics and climate.
qTraction-AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B, and C. These 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.
WARNING
The traction grade assigned to this tire is based on braking (straight ahead) traction
tests and does not include acceleration cornering (turning), hydroplaning, or peak
traction characteristics.
qTemperature-A, B, C
The temperature grades A (the highest), B, and C, represent 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.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire
life, and excessive temperatures can lead to sudden tire failure.
Grade C corresponds to a level of performance which all passenger vehicle tires must meet
under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory test wheel than the minimum required by
law.

WARNING
Keep your vehicle's tires properly inflated and not overloaded:Driving with improperly inflated or overloaded tires is dangerous. Excessive speed,
underinflation, or excessive loading, either separately or in combination, can cause
heat buildup and possible tire failure. The temperature grade for this tire is
established for a tire that is properly inflated and not overloaded.
These grades will be added to the sidewalls of passenger vehicle tires over the next several
years according to a schedule established by the NHTSA and the tire manufacturers.
The grade of tires available as standard or optional equipment on Mazda vehicles may vary
with respect to grade.
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND
TO ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.
q Uniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR 200 TRACTION AA
TEMPERATURE A
