WARNING
Keep your vehicle's tires properly inflated and not overloaded:Driving with improperly inflated or overloaded tires is dangerous. Excessive speed,
underinflation, or excessive loading, either separately or in combination, can cause
heat buildup and possible tire failure. The temperature grade for this tire is
established for a tire that is properly inflated and not overloaded.
These grades will be added to the sidewalls of passenger vehicle tires over the next several
years according to a schedule established by the NHTSA and the tire manufacturers.
The grade of tires available as standard or optional equipment on Mazda vehicles may vary
with respect to grade.
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO THESE GRADES AND
TO ALL OTHER FEDERAL TIRE-SAFETY REQUIREMENTS.
q UNIFORM TIRE QUALITY GRADING
Quality grades can be found where applicable on the tire sidewall between tread shoulder
and maximum section width.
For example:

14. SAFETY WARNING
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.
65
“ 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 ”.
15
“15 ”is the wheel rim diameter in inches.
95
“95 ”is the Load Index. This two-or three-digit number indicates how much weight each
tire can support.

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 specified 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 specified 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 specified 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:
lEXPLOSION 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.
lTIRE FAILURE DUE TO UNDER-INFLATION/OVERLOADING/DAMAGE-

WARNING
Always check the tire inflation pressures on a regular basis according to the
recommended tire inflation pressure on the tire label and in conjunction with the
information in this owner's manual:Driving your vehicle with under-inflated tires is dangerous.
Under-inflation 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-inflation increases sidewall flexing
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 flat!
It is impossible to determine whether or not tires are properly inflated just by looking
at them.
q 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 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.
6. Replace the valve cap.
7. Repeat with each tire, including the spare.
NOTE
Some spare tires require higher inflation 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.
NOTE
Warm tires normally exceed recommended pressures. Don't release air from warm tires to adjust the
pressure.
Under-inflation can cause serious failures and accidents.
Over-inflation can produce a harsh ride and the greater possibility of damage from road hazards.

CAUTION
Rotate unidirectional tires and radial tires that have an asymmetrical tread pattern
or studs only from front to rear, not from side to side. Tire performance will be
weakened if rotated from side to side.
(With limited-slip differential)
Don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed, the rotation of the left and right wheels will be
different and will thus apply a constant load on the limited-slip differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduced braking, steering, and traction could
result in an accident.
If a tire wears evenly, a wear indicator will appear as a solid band across the tread.
Replace the tire when this happens.
New tread Tread wear indicator
Worn tread
You should replace the tire before the band crosses the entire tread.
NOTE
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. 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 9-23.

Vehicle Loading
WARNING
Do not tow a trailer with this vehicle:Towing a trailer with this vehicle is dangerous because it has not been designed to
tow a trailer and doing so will affect the drive system which could result in vehicle
damage.
This section will guide you in the proper loading of your vehicle, to keep your loaded
vehicle weight within its design rating capability. Properly loading your vehicle will
provide maximum return of vehicle design performance. Before loading your vehicle,
familiarize yourself with the following terms for determining your vehicle's weight ratings,
from the vehicle's Safety Certification Label and Tire and Load Information Label:
WARNING
Overloaded Vehicle: Overloading a vehicle is dangerous. The results of overloading can have serious
consequences in terms of passenger safety. Too much weight on a vehicle's
suspension system can cause spring or shock absorber failure, brake failure,
handling or steering problems, irregular tire wear, tire failure or other damage.
Overloading makes a vehicle harder to drive and control. It also increases the
distance required for stopping. In cases of serious overloading, brakes can fail
completely, particularly on steep grades. The load a tire will carry safely is a
combination of the size of the tire, its load range, and corresponding inflation
pressure.
Never overload the vehicle and always observe the vehicle's weight ratings from the
vehicle's Safety Certification and Tire and Load Information labels.

GCW
GCW (Gross Combination Weight)is the weight of the loaded vehicle (GVW).
GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the
vehicle - including all cargo and passengers - that the vehicle can handle without risking
damage. The GCW must never exceed the GCWR.
WARNING
Exceeding GVWR or GAWR Specifications:
Exceeding the GVWR or the GAWR specified on the certification label is dangerous.
Exceeding any vehicle rating limitation could result in a serious accident, injury, or
damage to the vehicle.
Do not use replacement tires with lower load carrying capacities than the originals
because they may lower the vehicle's GVWR and GAWR limitations. Replacement
tires with a higher limit than the originals do not increase the GVWR and GAWR
limitations.
Never exceed the GVWR or the GAWR specified on the certification label.
