Installing the spare tire
1
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come
off.
2
Install the spare tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.
Tighten the wheel nuts until the
tapered portion comes into loose
contact with the disc wheel seat.
