2005 MAZDA MODEL B3000 TRUCK tire pressure

Additional information contained on the tire sidewall for “LT” type
tires
“LT” type tires have some additional
information than those of “P” 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 “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.

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!
When weather temperature changes occur, tire inflation pressures also
change. A 10 degree temperature change causes a corresponding drop of
7 kPa (1 psi) in inflation pressure. Check your tire pressures frequently
and adjust them to the proper pressure which can be found on the tire
label or certification label.
If checking tire pressure when the tire is hot, (i.e. driven more than 1.6
km [1mile]), 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.
3. Add 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 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).
