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.
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 objec\
ts 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, crac\
ks 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 Identification Number (TIN): A number on the sidewall of each tire providing
information about the tire brand and manufacturing plant, tire size, and\
date of manufacture.
Inflation Pressure: A measure of the amount of air in a tire.
kPa: Kilopascal, the metric unit for air pressure.
psi: Pounds per square inch, the English unit for air pressure.
B-pillar: The structural member at the side of the vehicle behind the front door.
Original Equipment (OE): Describes components originally equipped on the vehicle.
Vehicle Load Limit: The maximum value of the combination weight of occupants and
cargo.
Bead Area of the Tire: Area of the tire next to the rim.
Sidewall Area of the Tire: Area between the bead area and the tread.
Tread Area of the Tire: Area on the perimeter of the tire that contacts the road when it's
mounted on the vehicle.
Seating capacity means the total allowable number of vehicle occupants. Seating capacity\

is described on the tire label.
Production options weight is the combination weight of installed regular production
options weighing over 2.3 kilograms in excess of the standard items whic\
h they replace,
and not previously considered in the curb weight or accessory weight, in\
cluding heavy duty
brakes, ride levelers, roof rack, heavy duty battery, and special trim.
Rim is the metal support (wheel) for a tire or a tire and tube assembly u\
pon which the tire
beads are seated.

Tire Maintenance
Improper or inadequate vehicle maintenance can cause tires to wear abnor\
mally. 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 information 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 soon\
er
if irregular wear develops. Mazda recommends to rotate every 8,000 km (\
5,000 miles) to
help increase tire life and distribute 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 specification (page 9-8) and inspect the lug
nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure m\
onitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-96.

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:
 Tires not of the designated size Tires of different sizes or types at the same time 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.
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.
(With tire pressure monitoring system)
After adjusting the tire pressure, initialization of the tire pressure m\
onitoring system is
necessary to make the system operate normally.
Refer to Tire Pressure Monitoring System Initialization on page 4-96.

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 ke\
ep 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.
