MAZDA MODEL B2300 TRUCK 2008 Owners Manual (in English)

Every day before you drive, check your tires. If one looks lower than the
others, use a tire gauge to check pressure of all tires and adjust if
required.
At least once a month and before long trips, inspect each tire and check
the tire pressure with a tire gauge (including spare, if equipped). Inflate
all tires to the inflation pressure recommended by Mazda.
Use a tire gauge to check the tire inflation pressure, including the spare
(if equipped), at least monthly and before long trips. You are strongly
urged to buy a reliable tire pressure gauge, as automatic service station
gauges may be inaccurate. Mazda recommends the use of a digital or dial
type tire pressure gauge rather than a stick type tire pressure gauge.
Use the recommended cold inflation pressure for optimum tire
performance and wear. Under-inflation or over-inflation may cause
uneven treadwear patterns.
NOTE:If you are driving the vehicle at its maximum weight load, make
sure the tire inflation pressure is correct for the weight load on the tires.
WARNING: Under-inflation is the most common cause of tire
failures and may result in severe tire 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 also may result in unnecessary
tire stress, irregular wear, loss of vehicle control and accidents.
A tire can lose up to half of its air pressure and not appear to
be flat!
Always inflate your tires to the Mazda recommended inflation pressure
even if it is less than the maximum inflation pressure information found
on the tire. The Mazda recommended tire inflation pressure is found on
the Safety Compliance Certification Label or Tire Label which is located
on the B-Pillar or the edge of the driver’s door. Failure to follow the tire
pressure recommendations can cause uneven treadwear patterns and
adversely affect the way your vehicle handles.
Maximum Permissible Inflation Pressure is the tire manufactures’
maximum permissible pressure and/or the pressure at which the
maximum load can be carried by the tire. This pressure is normally
higher than the manufacturer’s recommended cold inflation pressure
which can be found on either the Safety Compliance Certification Label
or Tire Label which is located on the B-Pillar or the edge of the driver’s

door. The cold inflation pressure should never be set lower than the
recommended pressure on the Safety Compliance Certification Label or
Tire Label.
When weather temperature changes occur, tire inflation pressures also
change. A 10° F (6° C) temperature drop can cause a corresponding
drop of 1 psi (7 kPa) in inflation pressure. Check your tire pressures
frequently and adjust them to the proper pressure which can be found
on the Safety Compliance Certification Label or Tire Label.
If you are checking tire pressure when the tire is hot, (i.e. driven more
than 1 mile [1.6 km]), never “bleed” or reduce air pressure. The tires are
hot from driving and it is normal for pressures to increase above
recommended cold pressures. A hot tire at or below recommended cold
inflation pressure could be significantly under-inflated.
To check the pressure in your tire(s):1. Make sure the tires are cool, meaning they are not hot from driving even a mile.
Note: If you have to drive a distance to get air for your tire(s), check
and record the tire pressure first and add the appropriate air pressure
when you get to the pump. It is normal for tires to heat up and the air
pressure inside to go up as you drive. Never “bleed” or reduce air
pressure when tires are hot.
2. Remove the cap from the valve on one tire, then firmly press the tire gauge onto the valve and measure the pressure.
3. Add enough air to reach the recommended air pressure
Note: 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.
4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note: Some spare tires operate at a higher inflation pressure than the
other tires. For T-type/mini-spare tires (see T-Type/Mini-Spare Tire
Information section for description): Store and maintain at 60psi
(4.15 bars). For Full Size and Dissimilar spare tires (see Dissimilar
Spare Tire/Wheel Information section for description): Store and
maintain at the higher of the front and rear inflation pressure as shown
on the Safety Compliance Certification Label.
6. 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.

7. Check the sidewalls to make sure there are no gouges, cuts orbulges.
TIRE CARE
Inspecting your tires
Periodically inspect the tire treads for uneven or excessive wear and
remove objects such as stones, nails or glass that may be wedged in the
tread grooves. Check for holes or cuts that may permit air leakage from
the tire and make necessary repairs. Also inspect the tire sidewalls for
cracking, cuts, bruises and other signs of damage or excessive wear. If
internal damage to the tire is suspected, have the tire demounted and
inspected in case it needs to be repaired or replaced. For your safety,
tires that are damaged or show signs of excessive wear should not be
used because they are more likely to blow out or fail.
Improper or inadequate vehicle maintenance can cause tires to wear
abnormally. Inspect all your tires, including the spare, frequently, and
replace them if one or more of the following conditions exist:
Tire wear
When the tread is worn down to
1/16th of an inch (2 mm), tires must
be replaced to help prevent your
vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or “wear bars”, which
look like narrow strips of smooth
rubber across the tread will appear
on the tire when the tread is worn
down to 1/16th of an inch (2 mm).
When the tire tread wears down to
the same height as these “wear bars”, the tire is worn out and must be
replaced.
Damage
Periodically inspect the tire treads and sidewalls for damage (such as
bulges in the tread or sidewalls, cracks in the tread groove and
separation in the tread or sidewall). If damage is observed or suspected
have the tire inspected by a tire professional. Tires can be damaged
during off-road use, so inspection after off-road use is also
recommended.

WARNING: Age
Tires degrade over time depending on many factors such as
weather, storage conditions, and conditions of use (load, speed,
inflation pressure, etc.) the tires experience throughout their
lives.
In general, tires should be replaced after six years regardless of
tread wear. However, heat caused by hot climates or frequent
high loading conditions can accelerate the aging process and
may require tires to be replaced more frequently.
You should replace your spare tire when you replace the road
tires or after six years due to aging even if it has not been
used.
U.S. DOT Tire Identification Number (TIN)
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
This begins with the letters “DOT” and indicates that the tire meets all
federal standards. The next two numbers or letters are the plant code
designating where it was manufactured, the next two are the tire size
code and the last four numbers represent the week and year the tire was
built. For example, the numbers 317 mean the 31st week of 1997. After
2000 the numbers go to four digits. For example, 2501 means the 25th
week of 2001. The numbers in between are identification codes used for
traceability. This information is used to contact customers if a tire defect
requires a recall.
Tire replacement requirements
Your vehicle is equipped with tires designed to provide a safe ride and
handling capability.

WARNING: Only use replacement tires and wheels that are the
same size, load index, speed rating and type (such as P-metric
versus LT-metric or all-season versus all-terrain) as those
originally provided by Mazda. The recommended tire and wheel
size may be found on either the Safety Compliance Certification
Label or the Tire Label which is located on the B-Pillar or edge
of the driver’s door. If this information is not found on these
labels then you should consult your Mazda dealer. Use of any
tire or wheel not recommended by Mazda can affect the safety
and performance of your vehicle, which could result in an
increased risk of loss of vehicle control, vehicle rollover,
personal injury and death. Additionally the use of
non-recommended tires and wheels could cause steering,
suspension, axle or transfer case/power transfer unit failure. If
you have questions regarding tire replacement, see an
authorized dealer.
WARNING: When mounting replacement tires and wheels, you
should not exceed the maximum pressure indicated on the
sidewall of the tire to set the beads without additional
precautions listed below. If the beads do not seat at the
maximum pressure indicated, re-lubricate and try again.
When inflating the tire for mounting pressures up to 20 psi
greater than the maximum pressure on the tire sidewall, the
following precautions must be taken to protect the person
mounting the tire:
1. Make sure that you have the correct tire and wheel size.
2. Lubricate the tire bead and wheel bead seat area again.
3. Stand at a minimum of 12 feet away from the tire wheel assembly.
4. Use both eye and ear protection.
For a mounting pressure more than 20 psi greater than the maximum
pressure, a Mazda Dealer or other tire service professional should do
the mounting.
Always inflate steel carcass tires with a remote air fill with the person
inflating standing at a minimum of 12 ft. away from the tire wheel
assembly.
Important: Remember to replace the wheel valve stems when the road
tires are replaced on your vehicle.

It is recommended that the two front tires or two rear tires generally be
replaced as a pair.
The tire pressure sensors mounted in the wheels (originally installed on
your vehicle) are not designed to be used in aftermarket wheels.
The use of wheels or tires not recommended by Mazda Motor
Corporation may affect the operation of your Tire Pressure Monitoring
System.
If the TPMS indicator is flashing, your TPMS is malfunctioning. Your
replacement tire might be incompatible with your TPMS, or some
component of the TPMS may be damaged.
Safety practices
Driving habits have a great deal to do with your tire mileage and safety.
•Observe posted speed limits
• Avoid fast starts, stops and turns
• Avoid potholes and objects on the road
• Do not run over curbs or hit the tire against a curb when parking
WARNING: If your vehicle is stuck in snow, mud, sand, etc., do
not rapidly spin the tires; spinning the tires can tear the tire
and cause an explosion. A tire can explode in as little as three
to five seconds.
WARNING: Do not spin the wheels at over 35 mph (56 km/h).
The tires may fail and injure a passenger or bystander.
Highway hazards
No matter how carefully you drive there’s always the possibility that you
may eventually have a flat tire on the highway. Drive slowly to the
closest safe area out of traffic. This may further damage the flat tire, but
your safety is more important.
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 tires for damage. If a tire is under-inflated or damaged,
deflate it, remove wheel and replace it with your spare tire and wheel. If
you cannot detect a cause, have the vehicle towed to the nearest repair
facility or tire dealer to have the vehicle inspected.

Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side, vibrate or shake when you’re driving,
the wheels may be out of alignment. Have a qualified technician at a
Mazda dealer check the wheel alignment periodically.
Wheel misalignment in the front or the rear can cause uneven and rapid
treadwear of your tires and should be corrected by a qualified technician
at a Mazda dealer. Front wheel drive (FWD) vehicles and those with an
independent rear suspension require alignment of all four wheels.
The tire should also be balanced periodically. An unbalanced tire and
wheel assembly may result in irregular tire wear.
NOTE:When it is time to replace front tires with new ones, this is an
ideal time to perform an alignment. New tires should be balanced at the
time they are installed.
Tire rotation
Rotating your tires at the recommended interval (as indicated in the
Scheduled maintenance section of theMaintenance and
Specifications chapter) will help your tires wear more evenly, providing
better tire performance and longer tire life.

Note:If your tires show uneven wear ask a qualified technician at a
Mazda dealership to check for and correct any wheel misalignment, tire
imbalance or mechanical problem involved before tire rotation.
Note: Your vehicle may be equipped with a dissimilar spare tire/wheel. A
dissimilar spare tire/wheel is defined as a spare tire and/or wheel that is
different in brand, size or appearance from the road tires and wheels. If
you have a dissimilar spare tire/wheel it is intended for temporary use
only and should not be used in a tire rotation.
Note: After having your tires rotated, inflation pressure must be checked
and adjusted to the vehicle requirements.
INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require tire manufacturers to
place standardized information on the sidewall of all tires. This
information identifies and describes the fundamental characteristics of
the tire and also provides a U.S. DOT Tire Identification Number for
safety standard certification and in case of a recall.
Information on “P” type tires
P215/65R15 95H is an example of a
tire size, load index and speed
rating. The definitions of these
items are listed below. (Note that
the tire size, load index and speed
rating for your vehicle may be
different from this example.)
1. P:Indicates a tire, designated
by the Tire and Rim Association
(T&RA), that may be used for
service on cars, SUVs, minivans
and light trucks.
Note: If your tire size does not
begin with a letter this may mean it
is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire
Manufacturing Association).
2. 215: Indicates the nominal width of the tire in millimeters from
sidewall edge to sidewall edge. In general, the larger the number, the
wider the tire.
3. 65: Indicates the aspect ratio which gives the tire’s ratio of height to
width.

4.R: Indicates a “radial” type tire.
5. 15: Indicates the wheel or rim diameter in inches. If you change
your wheel size, you will have to purchase new tires to match the
new wheel diameter.
6. 95: Indicates the tire’s load index. It is an index that relates to how
much weight a tire can carry. You may find this information in your
Owner’s Manual. If not, contact a local tire dealer.
Note: You may not find this information on all tires because it is not
required by federal law.
7. H: Indicates the tire’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods
of time under a standard condition of load and inflation pressure.
The tires on your vehicle may operate at different conditions for load
and inflation pressure. These speed ratings may need to be adjusted
for the difference in conditions. The ratings range from 81 mph
(130 km/h) to 186 mph (299 km/h). These ratings are listed in the
following chart.
Note: You may not find this information on all tires because it is not
required by federal law.
Letter rating Speed rating - mph (km/h)
M 81 mph (130 km/h)
N 87 mph (140 km/h)
Q 99 mph (159 km/h)
R 106 mph (171 km/h)
S 112 mph (180 km/h)
T 118 mph (190 km/h)
U 124 mph (200 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (299 km/h)
Note: For tires with a maximum speed capability over 149 mph
(240 km/h), tire manufacturers sometimes use the letters ZR. For
those with a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
