with the rounded end of
the nuts toward the

Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to come loose

accident. Be sure to use the correct wheel
nuts. If you have to replace them, be sure to
get new GM original equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to the
proper torque specification. See "Capacities
and Specifications" in the Index for wheel nut
torque specification.
