Keep your tire pressure at the correct
levels. If one frequently needsinflating, have it inspected.Rotating the Tires
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.
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.
Also, inspect them for uneven wear
and damage. Abnormal wear is usually
caused by one or a combination of the
following:
Incorrect tire pressureImproper wheel alignmentOut-of-balance wheelSevere braking
After rotation, inflate all tire pressures
to specification (page 10-71) 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 or aWheel
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.
Always use wheels of the correct size
on your vehicle.
Using a wrong-sized wheel is
dangerous. Braking and handling could
be affected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:
Tire fit
Wheel and bearing life
Ground clearance
Snow-chain clearance
Speedometer calibration
Headlight aim
Bumper height
Tire Pressure Monitoring System
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.

Traction-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.
Temperature-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.

Tire Ply Composition and Materials
Used
The number of plies indicates the
number of layers of rubber-coated
fabric in the tire. In general, the greater
the number of plies, the more weight a
tire can support. Tire manufacturers
also must indicate the tire materials,
which include steel, nylon, polyester,
and other.

conditions.
Tread Wear, Traction and Temperature
Grades
Trea d wea r : 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.
Tra c t i o n : 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.

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.
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 pressureImproper wheel alignmentOut-of-balance wheelSevere braking
After rotation, inflate all tire pressures
to specification on page 10-71 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.
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 load ing 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 10-30.

GCW (Gross Combination Weight) is the weight of the loaded vehicle (GVW) plus
the weight of the fully loaded trailer.
GCWR (Gross Combination Weight Rating) is the maximum allowable weight of
the vehicle and the loaded trailer - incl uding all cargo and passengers - that the
vehicle can handle without risking damage. (Important: The towing vehicle's braking
system is rated for operation at GVWR, not at GCWR. Separate functional brakes
should be used for safe control of towed vehicles and for trailers weighing more than
1,500 lbs). The GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight is the highest possible weight of a fully loaded
trailer the vehicle can tow. It assumes a vehicle with only mandatory options, no
cargo (internal or external), a tongue load of 10 -15% (conventional trailer) or king
pin weight of 15 -25% (fifth-wheel trailer), and driver only (150 lbs). Consult your
dealership (or the RV and Trailer Towing Guide provided by your dealership) for
more detailed information.
Tongue Load or Fifth-Wheel King Pin Weight refers to the amount of the weight that
a trailer pushes down on a trailer hitch.
Examples: For a 5000 lb conventional trailer, multiply 5000 by 0.10 and 0.15 to
obtain a proper tongue load range of 500 to 750 lbs. For an 11,500 lb fifth-wheel
trailer, multiply by 0.15 and 0.25 to obt ain a proper king pin load range of 1,725 to
2,875 lbs.
WARNING
Never Exceed GVWR or GAWR Specifications.
Exceeding the GVWR or the GAWR specified on the certification label is dangerous.
Exceeding any vehicle rating limitation could result in a serious accident, injury, or
damage to the vehicle.
Do not use replacement tires with lower lo ad carrying capacities than the originals
because they may lower the vehicle's GVWR and GAWR limitations. Replacement
tires with a higher limit than the orig inals do not increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
