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

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 o ff
and cause an accident.
