Also, inspect them for uneven wear
and damage. Abnormal wear is usually
caused by one or a combination of the
following:
Incorrect tyre pressure

Improper wheel alignment

Out-of-balance wheel

Severe braking

After rotation, inflate all tyre pressures
to specification (page 9-12) and
inspect the wheel nuts for tightness.
CAUTION
Rotate unidirectional tyres and radial
tyres that have an asymmetrical tread
pattern or studs only from front to rear,
not from side to side. Tyre
performance will be reduced if rotated
from side to side.
▼ Replacing a Tyre
WARNING
Always use tyres that are in good
condition:
Driving with worn tyres is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Replace all four tyres at the same
time:
Replacing just one tyre is dangerous. It
could cause poor handling and poor
braking resulting in loss of vehicle
control. Mazda strongly recommends
that you replace all four tyres at the
same time.
Owner Maintenance
If a tyre wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tyre when this happens.
1. New tread
2. Worn tread
3. Tread wear indicator
You should replace the tyre before the
band crosses the entire tread.
▼ Temporary Spare Tyre
Inspect the temporary spare tyre at
least monthly to make sure it is
properly inflated and stored.
NOTE
The temporary spare tyre condition
gradually deteriorates even if it has not
been used.
The temporary spare tyre is easier to
handle because of its construction
which is lighter and smaller than a
conventional tyre. This tyre should be
used only for an emergency and only
for a short distance.
Use the temporary spare tyre only until
the conventional tyre is repaired,
which should be as soon as possible.
Refer to Tyre on page 9-12.
