2020 MAZDA MODEL CX-30 wheel size

CAUTION
Do not use your temporary spare tire
rim with a snow tire or a
conventional tire. Neither will
properly
fit and could damage both
tire and rim.
 The temporary spare tire has a tread
life of less than 5,000 km (3,000
miles). The tread life may be shorter
depending on driving conditions.
 The temporary spare tire is for
limited use, however, if the tread
wear solid-band indicator appears,
replace the tire with the same type of
temporary spare (page 6-30).
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. 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 8-22.
▼ Replacing a Wheel
WARNING
Always use wheels of the correct size
on your vehicle:
Using a wrong-sized wheel is
dangerous. Braking and handling could
be
affected, leading to loss of control
and an accident.
CAUTION
A wrong-sized wheel may adversely
affect:
 Tire
fit
 Wheel and bearing life
 Ground clearance
 Snow-chain clearance
 Speedometer calibration
 Headlight aim
 Bumper height
 Tire Pressure Monitoring System
NOTE
When replacing a wheel, make sure
the new one is the same as the
original factory wheel in diameter,
rim width, and offset (inset/outset).
For details, contact an Authorized
Mazda Dealer.

Proper tire balancing provides the best
riding comfort and helps reduce tread
wear. Out-of-balance tires can cause
vibration and uneven wear, such as
cupping and flat spots.

2. Put a vehicle with an automatictransmission in Park (P), a manual
transmission in Reverse (R) or 1,
and turn off the engine.
3. Turn on the hazard warning flasher.
4. Have passengers get out of the vehicle and away from the vehicle
and traffic.
5. Remove any luggage, the jack, tools, and spare tire (page 7-3).
6. Block the wheel diagonally opposite the flat tire. When
blocking a wheel, place a tire block
both in front and behind the tire.
NOTE
When blocking a tire, use rocks or
wood blocks of sufficient size if
possible to hold the tire in place.
▼Removing a Flat Tire
WARNING
When jacking-up a vehicle, always
shift the shift lever to 1st or R position
(manual transmission vehicle) or shift
the selector lever to P position
(automatic transmission vehicle),
apply the parking brake, and place
wheel blocks in the position
diagonally opposed to the jack:
Changing a flat tire without using
wheel blocks is dangerous because the
vehicle may move and fall off the jack
even with the shift lever in 1st or R
position, or the selector lever is in P
position, which could result in an
accident.
1. If your vehicle is equipped with a
wheel cover, pry off the wheel
cover with the beveled end of the
jack lever.

NOTE
Force the end of the jack lever
firmly between wheel and cover, or
removal will be difficult.
CAUTION
Align the notch on the wheel cover
with the valve stem when installing
it.

When the differential oil temperature
is excessively high.
When there is a large difference
between the front and rear wheel
rotation, such as when trying to

conditions. Inspect the tire sizes or tire
pressures on all 4 wheels. Contact an
Authorized Mazda Dealer if the
indication remains on or the warning
light remains illuminated.
When any of the tire diameter is
different.
When any of the tire pressure is
incorrect.
▼ TCS/DSC Indication/Indicator

If the light stays on, the TCS, DSC or
the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

consult an Authorized Mazda Dealer
as soon as possible. The system may
not operate in an accident.
WARNING
Never tamper with the air bag/
pretensioner systems and always have
an Authorized Mazda Dealer perform
all servicing and repairs:
Self-servicing or tampering with the
systems is dangerous. An air bag/
pretensioner could accidentally
activate or become disabled causing
serious injury or death.
▼Tire Pressure Monitoring System
(TPMS) Warning Indication/
Warning Light (Flashing)
If there is a problem with the TPMS or
the voltage of a tire pressure sensor

Tire Labeling
▼Tire Labeling
Federal law requires tire manufacturers
to place standardized information on
the sidewall of all tires. This
information identifies and describes
the fundamental characteristics of the
tire and also provides a tire
identification
number for safety
standard certification and in case of a
recall.
▼ Information on Passenger Vehicle

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” 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

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.

Location of the Tire Label (Placard)
▼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 original equipment on the vehicle. It
is very important that the inflation
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 inflation pressure is maintained.
Refer to Tires on page 9-7.
NOTE
Tire pressures listed on the vehicle
placard 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.
