Inspecting the Tires
About Tires
For reasons of proper performance,
safety, and better energy efficiency,
always maintain recommended tire
inflation pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using Different Tire Types.
Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires.
Using any other tire size than what is
specified for the vehicle (page
10-71)is dangerous. It could seriously
affect ride, handling, ground
clearance, tire clearance, and
speedometer calibration. This could
cause you to have an accident. Use
only tires that are the correct size
specified for the vehicle.

Inspecting tire inflation pressure
WARNING
Always inflate the tires to the correct
pressure.
Overinflation or underinflation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 10-71.
Use only a Mazda-genuine tire valve
cap.
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tire valve cap that is not a
Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended
pressures for the best ride, handling ,
and minimum tire wear.
Refer to the specification charts (page
10-71).
NOTE
Cold inflation pressure
The cold inflation pressure is the
pressure measured under ambient
temperatures before the vehicle is
driven.
Maximum inflation pressure
The maximum inflation pressure is
the upper limit of the cold inflation
pressure designated by the tire
manufacturer.
Recommended inflation pressure
The recommended inflation pressure
is the cold inflation pressure
necessary for maintaining the
performance of your Mazda.
Underinflation or overinflation can
cause a harsh ride, reduced fuel
economy, a greater possibility of
damage from road hazards, uneven
and accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.

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 pressureImproper wheel alignmentOut-of-balance wheelSevere braking

After rotation, inflate all tire pressures
to specification (page 10-71) and
inspect the lug nuts for tightness.

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 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 10-30.
Replacing Light Bulbs
All the light bulbs are the LED type.
The LED bulb cannot be replaced as a
single unit because it is an integrated
unit.
The LED bulb has to be replaced with
the unit. If a replacement is necessary,
consult an Authorized Mazda Dealer.
Adjusting the Headlight Aim
If the headlight cannot be adjusted
using procedure below, consult an
Authorized Mazda Dealer.
1. Make sure the vehicle has a fulltank of gasoline and the area
around the headlight is not
deformed.
2. Park the vehicle on level ground.
3. Sit in the driver's seat.
4. Bounce the vehicle several times.
5. Using a Phillips-head screw-driver, turn bolt A in either direction.
Remember the turning direction
and the number of turns.
6. Turn bolt B the same number of turns and in the same direction as
step 5.

1. Adjustment bolt A
2. Adjustment bolt B

Under-inflation is the most common
cause of failures in any kind of tire and
may result in severe cracking , tread
separation or “blowout”, with
unexpected loss of vehicle control and
increased risk of injury. Under-inflation
increases sidewall flexing and rolling
resistance, resulting in heat buildup
and internal damage to the tire. It
results in unnecessary tire stress,
irregular wear, loss of control and
accidents. A tire can lose up to half of
its air pressure and not appear to be
flat!
It is impossible to determine whether
or not tires are properly inflated just by
looking at them.Checking Tire Pressure
1. When you check the air pressure,make sure the tires are cold
―meaning they are not hot from
driving even a mile.
2. Remove the cap from the valve on
one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfill the tire, release air by pushing on the metal stem in the
center of the valve. Then recheck
the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher
inflation pressure.
8. Visually inspect the tires to make sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges,
cracks or other irregularities.

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 specified 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.
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, 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.

Safety Practices
The way you drive has a great deal to
do with your tire mileage and safety.
So cultivate good driving habits for
your own benefit.
Observe posted speed limits and
drive at speeds that are safe for the
existing weather conditions
Avoid fast starts, stops and turnsAvoid potholes and objects on the
road
Do not run over curbs or hit the tire
against the curb when parking
CAUTION
If you feel a sudden vibration or ride
disturbance while driving or you
suspect your tire or vehicle has been
damaged, immediately reduce your
speed. Drive with caution until you can
safely pull off the road. Stop and
inspect the tire for damage. If the tire
is under-inflated or damaged, deflate
it, remove the tire and rim and replace
it with your spare tire. If you cannot
detect a cause, have the vehicle towed
to the nearest vehicle or tire dealer to
have the vehicle inspected.
