spare wheel MAZDA MODEL B4000 TRUCK 2005 Owners Manual

•If steam is coming from the engine compartment:do not go near
the front of the vehicle. Stop the engine, then turn the ignition switch
to the ON position without starting the engine. The radiator cooling
fans will start to cool the engine.
• If neither coolant nor steam is escaping: open the hood and idle
the engine until it cools. If this does not lower the temperature, stop
the engine and let it cool.
5. Check the coolant level. If it is low, look for leaks in the radiator hoses and connections, heater hoses and connections, radiator and
water pump.
If you find a leak or other damage, or if coolant is still leaking, stop the
engine and call an Authorized Mazda dealer.
See Adding coolant in theMaintenance and specifications section. If
you find no problems, the engine is cool and no leaks are obvious,
carefully add coolant as required.
WARNING: When the engine and radiator are hot, scalding
coolant and steam may shoot out under pressure and cause
serious injury. Do not remove the cooling system cap when the
engine and radiator are hot.
Note: If the engine continues to overheat or frequently overheats, have
the cooling system inspected. The engine could be seriously damaged
unless repairs are made.
CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
WARNING: The use of tire sealants is not recommended and
may damage your tires.
Temporary spare tire information (if equipped)
Your vehicle may be equipped with a conventional spare tire that may be
different in size (smaller diameter and narrower width) than other tires
on your vehicle. If this is the case, your spare tire is considered
“temporary” and the spare wheel will be labeled as such. Replace this
tire with a tire of the same size, speed rating and load carrying capacity
as the other road tires as soon as possible.

It is not recommended that the vehicle be operated in 4WD modes with
a “temporary” (i.e. dissimilar size) spare. If 4WD operation is necessary,
do not operate above speeds of 16 km/h (10 mph) or for distances above
80 km (50 miles).WARNING: If you use the temporary spare tire continuously or
do not follow these precautions, the tire could fail, causing you
to lose control of the vehicle, possibly injuring yourself or
others.
When driving with the temporary spare tire do not:
• exceed 80 km/h (50 mph) or drive further than 3,200 km (2,000
miles) total under any circumstances
• load the vehicle beyond maximum vehicle load rating listed on the
Safety Compliance Label
• tow a trailer
• use more than one temporary spare tire at a time
Use of a temporary spare tire at any one wheel location can lead to
impairment of the following:
• Handling, stability and braking performance
• Comfort and noise
• Ground clearance and parking at curbs
• Winter driving capability
Conventional spare tire information (if equipped)
If you have the conventional spare tire, you can use it as a spare or a
regular tire. The spare is identical to the other tires on your vehicle,
although the wheel may not match.
Location of the spare tire and tools
The spare tire and tools for your vehicle are stowed in the following
locations:

•Rear
Never use the differential as a
jacking point. It is too easy for
the vehicle to tilt or fall and you
can be injured. 7. Remove the wheel lug nuts with the lug wrench.
8. Replace the flat tire with the spare tire, making sure the valve
stem is facing outward. Reinstall
the lug nuts until the wheel is
snug against the hub. Do not fully tighten the lug nuts until the
wheel has been lowered.
9. Lower the wheel by turning the jack handle counterclockwise.
10. Remove the jack and fully tighten the lug nuts, in the
order shown, to 135 Nm (100
lb-ft). Note that these tightening
specifications are for nut and
bolt threads that are free of dirt
and rust. Use only Mazda
recommended (1/2–20)
replacement fasteners.
11. Stow the flat tire. Refer to Stowing the spare tire.
12. Stow the jack and lug wrench. Make sure the jack is fastened so it does not rattle when you drive.

13. Unblock the wheels.
Stowing the flat/spare tire
Note:Failure to follow spare tire stowage instructions may result in
failure of cable or loss of spare tire.
1. Lay the tire on the ground with the valve stem facing up.
2. Slide the wheel partially under the vehicle and install the wire and retainer through the center of the wheel.
3. Turn the jack handle clockwise until the tire is raised to its original position underneath the vehicle. The effort to turn the jack handle
increases significantly as the tire contacts the frame. The spare tire
carrier will ratchet when the tire is in the fully stowed position. The
spare tire carrier has a built-in ratchet feature that will not allow you
to overtighten. If the spare tire carrier ratchets with very little effort,
take the vehicle to your dealer for assistance at your earliest
convenience.
4. Check that the tire lies flat against the frame assembly. Push against the tire to make sure it is tightly sealed under the vehicle. Loosen
and retighten, if necessary. Failure to properly stow the spare tire
may result in failure of the winch cable and loss of the spare tire.
5. Repeat this tightness check procedure when servicing the spare tire pressure (every six months, per service maintenance section), or at
any time that the spare tire is disturbed through service of other
components.
6. Install the spare tire lock (if equipped) into the access hole above the rear bumper with the spare tire lock key (if equipped) and jack
handle.

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 on “T” 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 “diagonal” type tire.
R: Indicates a “radial” 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.

4. Replace the valve cap.
5. Repeat this procedure for each tire, including the spare.
Note: Some spare tires require higher inflation pressure than the other
tires.
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, bulges or other irregularities.
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 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
reputable repair facility 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 reputable repair facility. Front wheel drive (FWD) vehicles, and
those with independent front 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
Service Maintenance Guide that comes with your vehicle) will help your
tires wear more evenly providing better tire performance and longer tire
life. Unless otherwise specified, rotate the tires approximately every
8,000 km (5,000 miles).
