Maintenance and Care
Owner Maintenance

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.
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.
Do not include (TEMPORARY USE ONLY)
spare tire in rotation.
Forward
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

Severe braking
After rotation, inflate all tire pressures to
specification (page 9-8) and inspect the
lug nuts for tightness.
(With tire pressure monitoring system)
After adjusting the tire pressure,
initialization of the tire pressure
monitoring system is necessary to make
the system operate normally.
Refer to Tire Pressure Monitoring System
Initialization on page 4-108.
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 reduced if rotated from side to
side.
(With limited-slip differential)
Do not use the following:

Tires not of the designated size

Tires of different sizes or types at
the same time

Tires not sufficiently inflated
If these instructions are not followed,
the rotation of the left and right wheels
will be different and will thus apply
a constant load on the limited-slip
differential.
This will cause a malfunction.
