2004 MAZDA MODEL B2300 TRUCK tire type

STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver's effort in steering the vehicle.
To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme right or the extreme left
for more than a few seconds when the engine is running.
²Do not operate the vehicle with the power steering pump fluid level
below the MIN mark on the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer the vehicle manually, but it takes more effort.
If the steering wanders or pulls, check for:
²Underinflated tire(s) on any wheel(s)
²Uneven vehicle loading
²High crown in center of road
²High crosswinds
²Wheels out of alignment
²Loose or worn suspension components
TRACTION-LOK AXLE/LIMITED SLIP DIFFERENTIAL (IF EQUIPPED)
This axle provides added traction on slippery surfaces, particularly when
one wheel is on a poor traction surface. Under normal conditions, the
Traction-Lok axle functions like a standard rear axle.
PREPARING TO DRIVE YOUR VEHICLE
WARNING: Utility vehicles have a significantly higher rollover
rate than other types of vehicles.
WARNING: In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing a safety
belt.
Your vehicle has larger tires and increased ground clearance, giving the
vehicle a higher center of gravity than a passenger car.

This is a lockout feature that protects the transmission from
accidentally being shifted into R (Reverse) from 5 (Overdrive).
Parking your vehicle
1. Apply the brake and shift into the neutral position.
2. Fully apply the parking brake, then shift into 1 (First).
3. Turn the ignition off.
WARNING: Do not park your vehicle in Neutral, it may move
unexpectedly and injure someone. Use 1 (First) gear and set
the parking brake fully.
Removing the key
Turn the ignition off, push the
release lever (located above the
ignition), then turn the key toward
you and remove the key.
If your vehicle gets stuck in mud or snow
If your vehicle gets stuck in mud or snow, it may be rocked out by
shifting from forward and reverse gears, stopping between shifts in a
steady pattern. Press lightly on the accelerator in each gear.
Do not rock the vehicle if the engine is not at normal operating
temperature or damage to the transmission may occur.
Do not rock the vehicle for more than a minute or damage to the
transmission and tires may occur, or the engine may overheat.
FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in

SPECIAL LOADING INSTRUCTIONS FOR OWNERS OF PICKUP
TRUCKS AND UTILITY-TYPE VEHICLES
WARNING: For important information regarding safe operation
of this type of vehicle, see the Preparing to drive your vehicle
section in this chapter.
WARNING: Loaded vehicles may handle differently than
unloaded vehicles. Extra precautions, such as slower speeds and
increased stopping distance, should be taken when driving a
heavily loaded vehicle.
Your vehicle can haul more cargo and people than most passenger cars.
Depending upon the type and placement of the load, hauling cargo and
people may raise the center of gravity of the vehicle.
Vehicle Loading ± with and without a trailer
This section will guide you in the proper loading of your vehicle and/or
trailer, to keep your loaded vehicle weight within its design rating
capability, with or without a trailer. 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, with or without a trailer, from the vehicle's
Safety Certification Label and Tire and Load Information Label:
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.
Cargo Weight± includes all weight added to the Base Curb Weight,
including cargo and optional equipment. When towing, trailer tongue load
or king pin weight is also part of cargo weight.

Keep a record for at least one month and record the type of driving (city
or highway). This will provide an accurate estimate of the vehicle's fuel
economy under current driving conditions. Additionally, keeping records
during summer and winter will show how temperature impacts fuel
economy. In general, lower temperatures give lower fuel economy.
Driving style Ð good driving and fuel economy habits
Give consideration to the lists that follow and you may be able to change
a number of variables and improve your fuel economy.
Habits
²Smooth, moderate operation can yield up to 10% savings in fuel.
²Steady speeds without stopping will usually give the best fuel
economy.
²Idling for long periods of time (greater than one minute) may waste
fuel.
²Anticipate stopping; slowing down may eliminate the need to stop.
²Sudden or hard accelerations may reduce fuel economy.
²Slow down gradually.
²Driving at reasonable speeds (traveling at 88 km/h [55 mph] uses 15%
less fuel than traveling at 105 km/h [65 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Using the air conditioner or defroster may reduce fuel economy.
²You may want to turn off the speed control in hilly terrain if
unnecessary shifting between fourth and fifth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
²Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
²Combine errands and minimize stop-and-go driving.
Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant specificationsin
this chapter.

Tire Quality Grades apply to new pneumatic tires for use on passenger
cars. They do not apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires, tires with nominal rim
diameters of 10 to 12 inches or limited production tires as defined in
Title 49 Code of Federal Regulations Part 575.104(c)(2).
U.S. Department of Transportation-Tire quality grades:The U.S.
Department of Transportation requires Mazda to give you the following
information about tire grades exactly as the government has written it.
Treadwear
The treadwear 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. The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices, and
differences in road characteristics and climate.
Traction AA A B C
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.
NOTE:The traction grade assigned to this tire is based on
straight-ahead braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
Temperature A B C
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. Sustained high temperature can cause the material of the tire
to degenerate and reduce tire life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds to a level of performance
which all passenger car 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.

INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires 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
tire identification number for safety standard certification and in case of
a recall.
Information on ªPº 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 than this example.)
1.P:Indicates a tire, designated
by the Tire and Rim Association
(T&RA), that maybe 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 ªradialº 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 guide. 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.

Additional information contained on the tire sidewall for ªLTº type
tires
ªLTº type tires have some additional
information than those of ªPº type
tires; these differences are
described below:
1.LT:Indicates a tire, designated
by the Tire and Rim Association
(T&RA), that is intended for
service on light trucks.
2.Load Range/Load Inflation
Limits:Indicates the tires
load-carrying capabilities and its
inflation limits.
3.Maximum Load Dual kg
(lbs.) at kPa (psi) cold:
Indicates the maximum load and
tire pressure when the tire is
used as a dual; a dual is defined as when four tires are put on the
rear axle (a total of six or more tires on the vehicle).
4.Maximum Load Single kg (lbs.) at kPa (psi) cold:Indicates the
maximum load and tire pressure when the tire is used as a single; a
single is defined as when two tires (total) are put on the rear axle.

Information on ªTº type tires
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different than
this example.
1.T:Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service
on cars, SUVs, minivans and
light trucks.
2.145: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.
3.80:Indicates the aspect ratio
which gives the tires ratio of height to width. Numbers of 70 or
lower indicate a short sidewall.
4.D:Indicates a ªdiagonalº type tire.
R:Indicates a ªradialº type tire.
5.16: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.
Location of the tire label
You will find a tire label containing tire inflation pressure by tire size and
other important information located on the B-Pillar or the driver's door.
TIRE CARE
Improper or inadequate vehicle maintenance can also cause tires to wear
abnormally. Here are some of the important maintenance items
Tire inflation pressure
Use a tire gauge to check the tire inflation pressure at least monthly
(check the tire inflation in the spare tire every 6 months) 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 of tire pressure gauge.
