7-2. Steps to take in an emergency
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 tire and loosely tighten each wheel nut by hand by
approximately the same amount.
When replacing a steel wheel
with a compact spare tire,
tighten the wheel nuts until the
tapered portion comes into
loose contact with the disc
wheel seat.
When replacing an aluminum
wheel with a compact spare
tire, tighten the wheel nuts until
the tapered portion comes into
loose contact with the disc
wheel seat.
3
