Buick 2013 Regal Owner's Manual page 336

In an emergency, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
13. Remove any rust or dirt from
the wheel bolts, mounting
surfaces, and spare wheel.
14. Place the compact spare tire
on the wheel-mounting surface.
Never use oil or grease on bolts
or nuts because the nuts might
come loose. The vehicle's wheel
could fall off, causing a crash.
15. Reinstall the wheel nuts.
Tighten each nut by hand until
the wheel is held against
the hub.
16. Lower the vehicle by turning
the jack handle
counterclockwise.
Wheel nuts that are improperly or
incorrectly tightened can cause
the wheels to become loose or
come off. The wheel nuts should
be tightened with a torque wrench
to the proper torque specification
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. See
original equipment wheel nut
torque specifications.
