Installing the spare tire
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.

contact surface, the wheel nuts
may loosen while the vehicle is
in motion, and the tire may
come off the vehicle.
Install the spare tire and loosely
tighten each nut by hand to
approximately the same amount.
Tighten the wheel nuts until the
tapered portion comes into
loose contact with the disc
wheel sheet.
Lower the vehicle.
