252 Vehicle Care
2. Tighten the inner wheel nuts of
the same wheel to the
specified torque.
3. Next, tighten the outer wheel
nuts to the specified torque.
Warning
If you find any abnormal
conditions with the wheel nuts
such as frequent loosening of
retightened nuts, have your
vehicle checked or serviced at the
nearest dealer as soon as
possible.
Fully engage the wheel wrench on a
wheel nut to be able to tighten the
nut to the specified torque.
However, do not use a pipe as a
handle extension or your foot to
apply force on the wrench. This
could tighten the nut more than
necessary and damage the
components.
Both under-tightening and
over-tightening the wheel nuts might
cause broken wheel studs or a
cracked disc wheel and could lead
to wheel detachment. Adhere to the
specified tightening torque.
When replacing a tire with a new
one, use only a tire of the same
type and size as the replaced tire;
otherwise, driving safety could be
compromised. Avoid mixing different
types and sizes of tires.
