Mazda CX-9 2019 Owner's Manual page 537

Use only a Mazda-genuine tire valve cap:
Use of a non-genuine part is dangerous as
the correct tire air pressure cannot be
maintained if the tire valve becomes
damaged. If the vehicle is driven under this
condition, the tire air pressure will decrease
which could result in a serious accident. Do
not use any part for the tire valve cap that
is not a Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended pressures for
the best ride, handling, and minimum tire
wear.
Refer to the specification charts (page
9-8).
NOTE
Always check tire pressure when tires

are cold.
Warm tires normally exceed

recommended pressures. Do not release
air from warm tires to adjust the
pressure.
Underinflation can cause reduced fuel

economy, uneven and accelerated tire
wear, and poor sealing of the tire bead,
which will deform the wheel and cause
separation of tire from rim.
Overinflation can produce a harsh ride,

uneven and accelerated tire wear, and a
greater possibility of damage from road
hazards.
Keep your tire pressure at the correct
levels. If one frequently needs inflating,
have it inspected.
Owner Maintenance
▼ Tire Rotation
WARNING
Rotate tires periodically:
Irregular tire wear is dangerous. To
equalize tread wear for maintaining good
performance in handling and braking,
rotate the tires every 12,000 km (7,500
miles). However Mazda recommends to
rotate every 8,000 km (5,000 miles) to help
increase tire life and distribute wear more
evenly.
Refer to Scheduled Maintenance on page
6-4.
During rotation, inspect them for correct
balance.
Forward
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.
Also, inspect them 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

