wheel MAZDA MODEL CX-30 2021 Owners Manual

Tread Wear, Traction and Temperature
Grades
Trea d wea 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.
Tra c t i o n : 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 te
st 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.

T115/70D16 90M 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.
T
Indicates a tire that may be installed on
cars, SUVs, minivans and light trucks as
designated by the Tire and Rim
Association (T&RA).
115
“115” 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.
70
“70” is the aspect ratio. This two-digit
number indicates the tire's ratio of
height to width.
D
“D” is the tire construction symbol. D
indicates “diagonal ply construction”.
16
“16” is the wheel rim diameter in
inches.
90
“90” is the Load Index. This two-or
three-digit number indicates how
much weight each tire can support.
M
“M” is the speed rating. The speed
rating denotes the maximum speed for
which the use of the tire is rated.
Letter Rating Speed Rating
M 81 mph

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 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 which they replace, and not
previously considered in the curb
weight or accessory weight, including
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 upon
which the tire beads are seated.

Tire Maintenance
▼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 information placard or tire label for
optimum service.
▼Tire Rotation
To equalize tread wear, rotate the tires
every 16,000 km (10,000 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 distribute
wear more evenly.
1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.

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 on page 9-8 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
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.
1. New tread
2. Worn tread
3. Tread wear indicator

You should replace the tire before the
band crosses the entire tread.
