Maintenance and Care
Owner Maintenance
*Some models.
CAUTION
 


¾ Do not use your temporary spare tire
rim with a snow tire or a conventional
tire. Neither will properly fi t and could
damage both tire and rim.
 


¾ The temporary spare tire has a tread life
of less than 5,000 km (3,000 miles). The
tread life may be shorter depending on
driving conditions.
 


¾ The temporary spare tire is for limited
use, however, if the tread wear solid-
band indicator appears, replace the tire
with the same type of temporary spare
(page 6-44 ).

N O T E
Tires degrade over time, even when
they are not being used on the road. It
is recommended that tires generally be
replaced when they are 6 years or older.
Heat caused by hot climates or frequent
high loading conditions can accelerate
the aging process. You should replace the
spare tire when you replace the other road
tires due to the aging of the spare tire. The
period in which the tire was manufactured
(both week and year) is indicated by a
4-digit number.
Refer to Tire Labeling on page 8-24 .

Replacing a Wheel
WARNING
Always use wheels of the correct size on
your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling
could be aff ected, leading to loss of
control and an accident.

CAUTION
A wrong-sized wheel may adversely
aff ect:




¾ Tire fi t



¾ Wheel and bearing life



¾ Ground clearance



¾ Snow-chain clearance



¾ Speedometer calibration



¾ Headlight aim



¾ Bumper height



¾ Tire Pressure Monitoring System *
N O T E




y When replacing a wheel, make sure
the new one is the same as the original
factory wheel in diameter, rim width,
and offset (inset/outset).
 


y For details, contact an Authorized
Mazda Dealer.


Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and À at spots.

If Trouble Arises
Flat Tire
Changing a Flat Tire
N O T E
If the following occurs while driving, it
could indicate a À at tire.




y Steering becomes dif¿ cult.



y The vehicle begins to vibrate
excessively.
 


y The vehicle pulls in one direction.
If you have a À at tire, drive slowly to a
level spot that is well off the road and out
of the way of traf¿ c to change the tire.
Stopping in traf¿ c or on the shoulder of a
busy road is dangerous.
WARNING
Be sure to follow the directions for
changing a tire:
Changing a tire is dangerous if not
done properly. The vehicle can slip off
the jack and seriously injure someone.
No person should place any portion
of their body under a vehicle that is
supported by a jack.

Never allow anyone inside a vehicle
supported by a jack:
Allowing someone to remain in
a vehicle supported by a jack is
dangerous. The occupant could cause
the vehicle to fall resulting in serious
injury.

N O T E
Make sure the jack is well lubricated
before using it.

1. Park on a level surface off the right-of-
way and ¿ rmly set the parking brake.
2. Shift into Park (P) and turn off the
engine.
3. Turn on the hazard warning À asher.
4. Have everyone get out of the vehicle
and away from the vehicle and traf¿ c.
5. Remove the jack, tool, and spare tire
(page 7-3 ).
6. Block the wheel diagonally opposite
the À at tire. When blocking a wheel,
place a tire block both in front and
behind the tire.


N O T E
When blocking a tire, use rocks or wood
blocks of suf¿ cient size if possible to hold
the tire in place.

all tires. This information identi¿ es and describes the fundamental characteristics of the tire
and also provides a tire identi¿ cation number for safety standard certi¿ cation and in case of
a recall.

Tire Information (U.S.A.)
P
Indicates a tire that may be installed on cars, SUVs, minivans and light trucks as designated
by the Tire and Rim Association (T&RA).
N O T E
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).

215
“215” is the nominal width of the tire in millimeters. This three-digit number gives the
width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger
the number, the wider the tire.
6 5
“65” is the aspect ratio. This two-digit number indicates the tire's ratio of height to width.
R
“R” is the tire construction symbol. R indicates “Radial ply construction”.
1 5
“15” is the wheel rim diameter in inches.
9 5
“95” is the Load Index. This two-or three-digit number indicates how much weight each tire
can support.
H
“H” is the speed rating. The speed rating denotes the maximum speed for which the use of
the tire is rated.

Tire Information (U.S.A.)
M S or M/S: Mud and Snow
AT: All Terrain.
AS: All Season. The “M
S” or “M/S” indicates that the tire has some functional use in mud
and snow.
U.S. DOT Tire Identi¿ cation Number (TIN)
This begins with the letters “DOT” which indicates the tire meets all federal standards. The
next two numbers or letters are the plant code where it was manufactured, and the last four
numbers represent the week and year the tire was manufactured. For example, the numbers
457 means the 45st week of 1997. After 2000 the numbers go to four digits. For example,
the number 2102 means the 21th week of 2002. The other numbers are marketing codes
used at the manufacturer's discretion. This information is used to contact consumers if a tire
defect requires a recall.
Tire Ply Composition and Materials Used
The number of plies indicates the number of layers of rubber-coated fabric in the tire.
In general, the greater the number of plies, the more weight a tire can support. Tire
manufacturers also must indicate the tire materials, which include steel, nylon, polyester,
and other.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds that can be carried by the
tire.
Maximum Permissible InÀ ation Pressure
This number is the greatest amount of air pressure that should ever be put in the tire under
normal driving conditions.
Tread Wear, Traction and Temperature Grades
Tread wear: The tread wear grade is a comparative rating based on the wear rate of the tire
when tested under controlled conditions on a speci¿ ed 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.
Traction: 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 speci¿ ed government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Temperature: 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 speci¿ ed indoor laboratory test wheel.
Snow Tires
In some heavy snow areas, local governments may require true snow tires, those with very
deeply cut tread. These tires should only be used in pairs or placed on all four wheels. Make
sure you purchase snow tires that are the same size and construction type as the other tires
on your vehicle.

Tire Information (U.S.A.)
Location of the Tire Label (Placard)
You will ¿ nd the tire label containing tire inÀ ation pressure by tire size and other important
information on the driver's side B-pillar or on the edge of the driver's door frame.

SAMPLE


Recommended Tire InÀ ation Pressure
On the tire label you will ¿ nd the recommended tire inÀ ation pressure in both kPa and
psi for the tires installed as original equipment on the vehicle. It is very important that the
inÀ ation pressure of the tires on your vehicle is maintained at the recommended pressure.
You should check the tire pressure regularly to insure that the proper inÀ ation pressure is
maintained.
Refer to Tires on page 9-8 .
N O T E
Tire pressures listed on the vehicle placard or tire information label indicate the
recommended cold tire inÀ ation pressure, measured when the tires are cold, after the vehicle
has been parked for at least 3 hours. As you drive, the temperature in the tire warms up,
increasing the tire pressure.
