WARNING
Always securely and correctly
tighten the lug nuts.
Improperly or loosely tightened lug
nuts are dangerous. The wheel
could wobble or come off. This
could result in loss of vehicle
control and cause a serious
accident.
Be sure to reinstall the same nuts
you removed or replace them with
metric nuts of the same
configuration.
Because the wheel studs and lug
nuts on your Mazda have metric
threads, using a non-metric nut is
dangerous. On a metric stud, it
would not secure the wheel and
would damage the stud, which
could cause the wheel to slip off
and cause an accident.

The number and shape of the flat
tire belt differ depending on the
vehicle specification.

1. Belt Clips
The flat tire belts with the clips
