2005 MAZDA MODEL B2300 TRUCK width

•Narrower—to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, SUV’s and trucks often
will have a higher center of gravity
and a greater difference in center of
gravity between the loaded and
unloaded condition.
These differences that make your
vehicle so versatile also make it
handle differently than an ordinary
passenger car.
INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
New vehicles are fitted with tires
that have a rating on them called
Tire Quality Grades. The Quality
grades can be found where
applicable on the tire sidewall
between tread shoulder and
maximum section width. For
example:
•Treadwear 200 Traction AA Temperature A
These Tire Quality Grades are determined by standards that the United
States Department of Transportation has set.
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

WARNING: When a wheel is installed, always remove any
corrosion, dirt and foreign materials present on the mounting
surfaces of the wheel and the surface of the front disc brake
hub and rotor that contacts the wheel. Installing wheels
without correct metal-to-metal contact at the wheel mounting
surfaces can cause the wheel nuts to loosen and the wheel to
come off while the vehicle is in motion, resulting in loss of
control.
Note:If there is corrosion on the area where the wheel contacts the
hub, apply a thin film of grease or anti-seize compound on that area.
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
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 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.
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.

Information on“T”type tires
“T”type tires have some additional
information beyond those of“P”
type tires; these differences are
described below:
T145/80D16 is an example of a tire
size.
Note:The temporary tire size for
your vehicle may be different from
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 tire’s 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 edge of 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 wear
Measure and inspect the tire tread on all your tires periodically.
Advanced and unusual tire wear can reduce the ability of tread to grip
