2010 MAZDA MODEL CX-7 tires

Black plate (421,1)
The Tire Pressure Monitoring Systemí
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.
Except Canada (Tire pressure label)
Canada (Motor vehicle safety standard
label)
Refer to the specification charts (page
10-7).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.
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:

After rotation, inflate all tire pressures to
specification (page 10-7) 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.
CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
ØTires of different sizes or types at
the same time
ØTires 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.
qReplacing 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.
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
5-31.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-31.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.

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 9-24.
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.
(Except Mexico)
Maintain its pressure at 420 kPa (4.2 bar,
60 psi).
(Mexico)
Maintain its pressure at 250 kPa (2.5 bar,
36 psi).
CAUTION
ØDo 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.
ØThe 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.
ØThe 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 8-38).
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

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 5-31.
When replacing a wheel, make sure the
new one is the same as the original factory
wheel in diameter, rim width, and offset.
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.

qUnderbody Maintenance
Road chemicals and salt used for ice and
snow removal and solvents used for dust
control may collect on the underbody. If
not removed, they will speed up rusting
and deterioration of such underbody parts
as fuel lines, frame, floor pan, and exhaust
system, even though these parts may be
coated with anti-corrosive material.
Thoroughly flush the underbody and
wheel housings with lukewarm or cold
water at the end of each winter. Try also
to do this every month.
Pay special attention to these areas
because they easily hide mud and dirt.It
will do more harm than good to wet
down the road grime without removing
it.
The lower edges of doors, rocker panels,
and frame members have drain holes that
should not be clogged. Water trapped
there will cause rusting.
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.
qUndercoating
This special coating is applied to the
critical parts of the underside to protect
vehicles from damage caused by
chemicals or stones. This coating is liable
to be damaged with time. Check this
coating periodically.
An Authorized Mazda Dealer are well
informed on how repairs should be made.
Consult an Authorized Mazda Dealer.
qAluminum Wheel Maintenanceí
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
NOTE
lDo not use a wire brush or any abrasive
cleaner, polishing compound, or solvent on
aluminum wheels. They may damage the
coating.
lOnly use a mild soap or neutral detergent
and always use a sponge or soft cloth to
clean the wheels.
Rinse thoroughly with lukewarm or cold
water. Also, be sure to clean the wheels
after driving on dusty or salted roads. This
helps 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.

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.
qUniform Tire Quality Grading
Quality grades can be found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example:
