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 Inflation 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
Tr e a d w e a r : 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 pave ment as measured under controlled conditions
on specified government test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance.
Te m p e r a t u r e : 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 specif ied 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.

Location of the Tire Label (Placard)
You will find the tire label containing tire inflation 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 Inflation Pressure
On the tire label you will find the recommended
tire inflation pressure in both kPa and psi
for the tires installed as origin al equipment on the vehicle. It is very important that the
inflation pressure of the tires on your vehicl e is maintained at the recommended pressure.
You should check the tire pressu re regularly to insure that the proper inflation pressure is
maintained.
Refer to Tires on page 9-7.
NOTE
Tire pressures listed on the vehicle placar d or tire information label indicate the
recommended cold tire inflation 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 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 inc reases 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 ti re 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.
▼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 push ing 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.
▼Glossary of Terms
Tire Placard:
A label indicating the OE tire sizes, recommended inflation pressure, and the
maximum weight the vehicle can carry.
Tire Identificatio n Number (TIN): A number on the sidewall of each tire providing
information about the tire brand and manufacturi ng plant, tire size, and date of manufacture.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnormally. Here are
some important maintenance points:
▼Tire Inflation Pressure
Inspect all tire pressure monthly (including the spare) when the tires are cold. Maintain
recommended pressures for the best ride, top handling, and minimum tire wear. Use the
pressures specified on the vehicle tire informat
ion placard or tire label for optimum service.
▼Tire Rotation
To equalize tread wear, rotate the tires every 12,000 km (7,500 miles) at the latest or sooner
if irregular wear develops. Mazda recommends to rotate every 8,000 km (5,000 miles) to
help increase tire life and di
stribute wear more evenly.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.Forward
Inspect the tires for uneven wear and damage. Abnormal wear is usually caused by one or a
combination of the following:
Incorrect tire pressure
Improper wheel alignment
Out-of-balance wheel
Severe braking
After rotation, inflate all tire pressures to sp ecification (page 9-7) and inspect the lug nuts
for tightness.
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.

▼Replacing a Tire
WA R N I N G
Always use tires that are in good condition:
Driving with worn tires is dangerous. Reduce
d 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 load ing conditions can accelerate the aging proc ess. 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 8-25.
▼ Safety Practices
The way you drive has a great deal to do with
your tire mileage and safety. So cultivate
good driving habits for your own benefit.
Observe posted speed limits and drive at speeds that are safe for the existing weather
conditions
Avoid fast starts, stops and turns
Avoid potholes and objects on the road
Do not run over curbs or hit the ti re against the curb when parking

GCW (Gross Combination Weight) is the weight of the loaded vehicle (GVW) plus the
weight of the fully loaded trailer.

GCWR (Gross Combination Weight Rating) is the maximum allowable weight of the
vehicle and the loaded trailer - including al l cargo and passengers - that the vehicle can
handle without risking damage. (Important: The towing vehicle's braking system is rated for
operation at GVWR, not at GCWR. Separate f unctional brakes should be used for safe
control of towed vehicles and for trailers weighing more than 1,500 lbs). The GCW must
never exceed the GCWR.

Maximum Loaded Trailer Weight is the highest possible weight of a fully loaded trailer
the vehicle can tow. It assumes a vehicle with only mandatory options, no cargo (internal or
external), a tongue load of 10 －15% (conventional trailer) or king pin weight of 15－25%
(fifth-wheel trailer), and driver only (150 lbs). Consult your dealership (or the RV and
Trailer Towing Guide provided by your de alership) for more detailed information.
Tongue Load or Fifth-Wheel King Pin Weight refers to the amount of the weight that a
trailer pushes down on a trailer hitch.

Examples: For a 5000 lb conventional trailer, multiply 5000 by 0.10 and 0.15 to obtain a
proper tongue load range of 500 to 750 lbs. For an 11,500 lb fifth-wheel trailer, multiply by
0.15 and 0.25 to obtain a proper king pin load range of 1,725 to 2,875 lbs.
WA R N I N G
Never Exceed 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.
