Chevrolet 1995 Tahoe Owner's Manual page 267

Changing the Tire
Start with the jack, the
jack handle and the
ratchet.
If the flat tire is on the
rear of the vehicle,
you'll need the jack
handle extensions
also.
Attach the jack handle (and jack handle extension, if needed)
to
the jack.
One side of the ratchet has an
UP marking. The other side has a DOWN marking.
With the UP marking
on the ratchet facing
you, rotate the ratchet
clockwise. That will
lift the jack head a
little.
Before you start, put the spare tire near the flat tire. Remove the wheel trim and
loosen the wheel nuts. The next part will show you how to do these things properly.
