tire pressure warning beep sound is heard,
decrease vehicle speed immediately and
avoid sudden maneuvering and braking: If the tire pressure monitoring system
warning light illuminates or fl ashes, or the
tire pressure warning beep sound is heard,
it is dangerous to drive the vehicle at high
speeds, or perform sudden maneuvering
or braking. Vehicle drivability could worsen
and result in an accident.

can check the visual condition of the tire
and determine if you have enough air to
proceed to a place where air may be added
and the system monitored again by an
Authorized Mazda Dealer or a tire repair
station.
Do not ignore the TPMS Warning Light: Ignoring the TPMS warning light is
dangerous, even if you know why it is
illuminated. Have the problem taken care of
as soon as possible before it develops into
a more serious situation that could lead to
tire failure and a dangerous accident. Inspect the tires and adjust to the
specifi
ed infl ation pressure (page 6-42 ).
NOTE
yPerform tire pressure adjustment when
the tires are cold. Tire pressure will
vary according to the tire temperature,
therefore let the vehicle stand for 1
hour or only drive it 1.6 km (1 mile) or
less before adjusting the tire pressures.
When pressure is adjusted on hot tires
to the cold infl ation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops below
specifi cation.
Also, an illuminated TPMS warning
light, resulting from the tire air
pressure dropping due to cold ambient
temperature will remain illuminated
even if the ambient temperature rises.
In this case, it will also be necessary
to adjust the tire air pressures. If the
TPMS warning light illuminates due to
a drop in tire air pressure, make sure to
check and adjust the tire air pressures.
yTires lose air naturally over time and the TPMS cannot tell if the tires are
getting too soft over time or you have
a fl at. However, when you fi nd one low
tire in a set of four-that is an indication
of trouble; you should have someone
drive the vehicle slowly forward so
you can inspect any low tire for cuts
and any metal objects sticking through
tread or sidewall. Put a few drops
of water in the valve stem to see if it
bubbles indicating a bad valve. Leaks
need to be addressed by more than
simply reinfl ating the tire as leaks are
dangerous — take it to an Authorized
Mazda Dealer.

P215/65R15 95H is an example of a tire size and load index rating. Here is an explanation
of the various components of that tire size and load index rating. Note that the tire size and
load index rating may be different from the example.
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).
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).
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”.

Maximum Permissible Infl 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 specifi 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 specifi 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 specifi 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.
SAFETY WARNING
The following safety warning appears on the tire's sidewall.
SERIOUS INJURY MAY RESULT FROM:
 


y EXPLOSION OF TIRE/RIM ASSEMBLY DUE TO IMPROPER MOUNTING-MATCH
TIRE DIAMETER TO RIM DIAMETER; NEVER EXCEED 40 psi (275 kPa) TO SEAT
BEADS-ONLY SPECIALLY TRAINED PERSONS SHOULD MOUNT TIRES.
 


y TIRE FAILURE DUE TO UNDER-INFLATION/OVERLOADING/DAMAGE-

Location of the Tire Label (Placard)
You will fi nd the tire label containing tire infl 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 Infl ation Pressure
On the tire label you will fi nd the recommended tire infl ation pressure in both kPa and
psi for the tires installed as original equipment on the vehicle. It is very important that the
infl 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 infl ation pressure is
maintained.
Refer to Tires on page 9-8 .
NOTE
Tire pressures listed on the vehicle placard or tire information label indicate the
recommended cold tire infl 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.

WARNING
Always check the tire infl ation pressures on a regular basis according to the
recommended tire infl ation pressure on the tire label and in conjunction with the
information in this owner's manual:
Driving your vehicle with under-infl ated tires is dangerous.
Under-infl ation is the most common cause of failures in any kind of tire and may result
in severe cracking, tread separation or “blowout”, with unexpected loss of vehicle
control and increased risk of injury. Under-infl ation increases sidewall fl exing and
rolling resistance, resulting in heat buildup and internal damage to the tire. It results in
unnecessary tire stress, irregular wear, loss of control and accidents. A tire can lose up to
half of its air pressure and not appear to be fl at!
It is impossible to determine whether or not tires are properly infl ated just by looking at
them.
Checking Tire Pressure
1. When you check the air pressure, make sure the tires are cold —meaning they are not hot
from driving even a mile.
2. Remove the cap from the valve on one tire.
3. Firmly press a tire gauge onto the valve.
4. Add air to achieve recommended air pressure.
5. If you overfi ll the tire, release air by pushing on the metal stem in the center of the valve.
Then recheck the pressure with your tire gauge.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher infl ation pressure.
8. 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.
9. Check the sidewalls to make sure there are no gouges, cuts, bulges, cracks or other
irregularities.
