2020 MAZDA MODEL CX-30 spare tire

hub, including the hub bolts, with a
cloth.

WARNING
Make sure the mounting surfaces
of the wheel, hub and lug nuts are
clean before changing or replacing
tires:
When changing or replacing a tire,
not removing dirt and grime from
the mounting surfaces of the wheel,
hub and hub bolts is dangerous.
The lug nuts could loosen while
driving and cause the tire to come
off, resulting in an accident.
2. Mount the spare tire.
3. Install the lug nuts with the beveled edge inward; tighten them by hand.

WARNING
Do not apply oil or grease to lug
nuts and bolts and do not tighten
the lug nuts beyond the
recommended tightening torque:
Applying oil or grease to lug nuts
and bolts is dangerous. The lug nuts
could loosen while driving and
cause the tire to come off, resulting
in an accident. In addition, lug nuts
and bolts could be damaged if
tightened more than necessary.
4. Turn the jack handle counterclockwise using the lug
wrench and lower the vehicle.
5. Use the lug wrench to tighten the nuts in the order shown.

If you are unsure of how tight the
nuts should be, have them
inspected at an Authorized Mazda
Dealer.

WARNING
Always securely and correctly
tighten the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel
could wobble or come
off. This
could result in loss of vehicle
control and cause a serious
accident.

16.Check the inflation pressure. Referto Tires on page 9-7.
17.Have the flat tire repaired or replaced as soon as possible.
WARNING
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tires' air
pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from
rattling, store them properly.

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
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 ma ximum 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.

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 (page 9-7) 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 8-22.
▼ 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 benefit.
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-inflated or damaged, deflate
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.
