▼Spare Tire
Your Mazda has a temporary spare tire.
The temporary spare tire is lighter and
smaller than a conventional tire, and is
designed only for emergency use and
should be used only for VERY short
periods. Temporary spare tires should
NEVER be used for long drives or
extended periods.
WA R N I N G
Do not install the temporary spare tire on
the front wheels (driving wheels):
Driving with the temporary spare tire on
one of the front driving wheels is
dangerous. Handling will be
affected. You
could lose control of the vehicle, especially
on ice or snow bound roads, and have an
accident. Move a regular tire to the front
wheel and install the temporary spare tire
to the rear.
CAUTION
 When using the temporary spare tire,
driving stability may decrease compared
to when using only the conventional tire.
Drive carefully.
 To avoid damage to the temporary spare
tire or to the vehicle, observe the
following precautions:
 Do not exceed 80 km/h (50 mph).
 Avoid driving over obstacles. Also, do
not drive through an automatic car
wash. This tire's diameter is smaller
than a conventional tire, so the ground
clearance is reduced.
 Do not use a tire chain on this tire
because it will not fit properly.
Do not use your temporary spare tire
on any other vehicle, it has been
designed only for your Mazda.
 Use only one temporary spare tire on
your vehicle at the same time.
To remove the spare tire
1. Remove the trunk mat.
