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.

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).

1Ensure the correct automatic transmission fluid is used. Transmission
fluid requirements are indicated on the dipstick or on the dipstick
handle. MERCONtand MERCONtV are not interchangeable. DO NOT
mix MERCONtand MERCONtV. Refer to the service maintenance
section to determine the correct service interval.
2Service refill capacity is determined by filling the transmission to the
bottom of the filler hole with the vehicle on a level surface.
3Indicates only approximate dry-fill capacity. Some applications may vary
based on cooler size and if equipped with an in-tank cooler. The amount
of transmission fluid and fluid level should be set by the indication on
the dipstick's normal operating range.
4Add the coolant type originally equipped in your vehicle. DO NOT MIX
different colors or types of coolant. DO NOT USE Mazda Extended Life
Engine Coolant (orange in color). Refer toAdding engine coolant, in
this chapter.

5Traction-Lok axles use 2.2±2.4L (4.75±5.0 pints) of rear axle lubricant.
Add 118 ml (4 oz.) of Additive Friction Modifier meeting Mazda
specifications for complete refill of Traction-Lok axles. Service refill
capacities are determined by filling the rear axle 6 mm to 14 mm (1/4
inch to 9/16 inch) below the bottom of the filler hole.
6Brake fluid will drop slowly as the brakes wear and will rise when brake
components are replaced. Fluid levels below the MAX line that do not
trigger the brake warning light are within the normal operating range,
there is no need to add fluid. If the levels are outside the normal
operating range, the performance of your brake system could be
compromised, seek service from your local Mazda dealer immediately.

CELL PHONES
Use of cell phones and other devices by driver:
WARNING: Use of any electrical devices such as cell phones,
computers, portable radios, vehicle navigation or other devices
by the driver while the vehicle is moving is dangerous. Dialing a
number on a cell phone while driving also ties-up the driver's
hands. Use of these devices will cause the driver to be
distracted and could lead to a serious accident. If a passenger is
unable to use the device, pull off the right-of-way to a safe area
before use. If use of a cell phone is necessary despite this
warning, use a hands-free system to at least allow the hands
free to drive the vehicle. Never use a cell phone or other
electrical device while the vehicle is moving and, instead,
concentrate on the full-time job of driving.
In addition, the gasoline distributors are warning against using
cell phones during refueling procedures, due to their increased
concern about static electricity fires in the self-service pump
environment.
