Owner Maintenance
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.

Some models.
If a tyre wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tyre when this happens.
New tread
You should replace the tyre before the
band crosses the entire tread.
After adjusting the tyre pressure,
initialization of the tyre pressure
monitoring system is necessary to make
the system operates normally.
Refer to Tyre Pressure Monitoring System
Initialization on page 4-145 .
Temporary Spare Tyre
Inspect the temporary spare tyre at least
monthly to make sure it is properly
infl ated 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.
