wheel size MAZDA MODEL CX-50 2023 Owner's Manual

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.

▼ Information on Temporary Tires
Please refer to the sample below.
1. Temporary tires
2. Nominal width of tire in millimeters
3. Ratio of height to width (aspect
ratio)
4. Diagonal
5. Rim diameter code
6. Load index & speed symbol

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
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.
