2022 MAZDA MODEL MX-30 EV tires

WARNING
Keep your vehicle's tires properly
inflated and not overloaded:
Driving with improperly inflated or
overloaded tires is dangerous.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat
buildup and possible tire failure. The
temperature grade for this tire is
established for a tire that is properly
in flated and not overloaded.

These grades will be added to the
sidewalls of passenger vehicle tires
over the next several years according to
a schedule established by the NHTSA
and the tire manufacturers.

The grade of tires available as standard
or optional equipment on Mazda
vehicles may vary with respect to
grade.

ALL PASSENGER VEHICLE TIRES MUST
CONFORM TO THESE GRADES AND
TO ALL OTHER FEDERAL TIRE -SAFETY
REQUIREMENTS.

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.
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 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 speci fied
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.

SAMPLE
▼ Recommended Tire In
flation
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 in flation pressure is maintained.
Refer to Tires on page 9-5.
NOTE
Tire pressures listed on the vehicle
placard or tire information label
indicate the recommended cold tire
in flation 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-in flated tires is dangerous.
Under-in flation 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
fl at!
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 over fill 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
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.

▼ 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 speci
fied 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, in flate all tire pressures
to speci fication on page 9-5 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.
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 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 8-21.
▼ 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 bene
fit.
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 tire
against the curb when parking
CAUTION
If you feel a sudden vibration or ride
disturbance while driving or you
suspect your tire or vehicle has been
damaged, immediately reduce your
speed. Drive with caution until you can
safely pull
off the road. Stop and
inspect the tire for damage. If the tire
is under-in flated or damaged, de flate
it, remove the tire and rim and replace
it with your spare tire. If you cannot
detect a cause, have the vehicle towed
to the nearest vehicle or tire dealer to
have the vehicle inspected.
