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.

WARNING
Do not tow a trailer with this vehicle:
Towing a trailer with this vehicle is
dangerous because it has not been
designed to tow a trailer and doing so
will
aff ect the drive system which could
result in vehicle damage.
This section will guide you in the
proper loading of your vehicle, to keep
your loaded vehicle weight within its
design rating capability. Properly
loading your vehicle will provide
maximum return of vehicle design
performance. Before loading your
vehicle, familiarize yourself with the
following terms for determining your
vehicle's weight ratings, from the
vehicle's Safety Certi fication Label and
Tire and Load Information Label:
WARNING
Overloaded Vehicle:
Overloading a vehicle is dangerous.
The results of overloading can have
serious consequences in terms of
passenger safety. Too much weight on
a vehicle's suspension system can
cause spring or shock absorber failure,
brake failure, handling or steering
problems, irregular tire wear, tire
failure or other damage.
Overloading makes a vehicle harder to
drive and control. It also increases the
distance required for stopping. In cases
of serious overloading, brakes can fail
completely, particularly on steep
grades. The load a tire will carry safely
is a combination of the size of the tire,
its load range, and corresponding
in flation pressure.
Never overload the vehicle and always
observe the vehicle's weight ratings
from the vehicle's Safety Certi fication
and Tire and Load Information labels.
Base Curb Weight is the weight of the
vehicle including a full tank of fuel
and all standard equipment. It does
not include passengers, cargo, or
optional equipment.

Vehicle Curb Weight is the weight of
your new vehicle when you picked it
up from your dealer plus any
aftermarket equipment.

GVW (Gross Vehicle Weight) is the
Vehicle Curb Weight + cargo +
passengers.

GVWR (Gross Vehicle Weight Rating)
is the maximum allowable weight of
the fully loaded vehicle (including all
options, equipment, passengers and
cargo). The GVWR is shown on the
Safety Compliance Certi fication Label
located on the driver's door frame or
door pillar. The GVW must never
exceed the GVWR.

SAMPLE
WARNING
Never Exceed Axle Weight Rating
Limits:
Exceeding the Safety Certification
Label axle weight rating limits is
dangerous and could result in death or
serious injury as a result of substandard
vehicle handling, performance, engine,
transmission and/or structural
damage, serious damage to the
vehicle, or loss of control.
Always keep the vehicle within the axle
weight rating limits.

GCW
GCW (Gross Combination Weight) is
the weight of the loaded vehicle
(GVW).

GCWR (Gross Combination Weight
Rating) is the maximum allowable
weight of the vehicle - including all
cargo and passengers - that the vehicle
can handle without risking damage.
The GCW must never exceed the
GCWR.

WARNING
Never Exceed GVWR or GAWR
Speci fications:
Exceeding the GVWR or the GAWR
speci fied on the certi fication 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 load carrying capacities than the
originals because they may lower the
vehicle's GVWR and GAWR
limitations. Replacement tires with a
higher limit than th e originals do not
increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR
speci fied on the certi fication label.
