Also, inspect them 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, inflate 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 reduced 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.
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.
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.

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.

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.
