it out of the gutter with the tire iron, moving pro­
gressively around the rim (fig. 7).
4. Drive the curved end of the tire iron in between the
side ring and the tire bead (fig. 8 ). Then pry down
on the opposite end of tire iron to move the tire bead
away from the side ring flange (fig.
9 ).
Continue the foregoing operation progressively
around the tire until the side ring is removed. In
some cases it may be necessary to work around the
tire more than once.
NOTE: The tire bead seat on the side ring is
slightly tapered; this design makes removal of
ring much easier.
5. Push the valve stem up inside the tire to prevent
damage while removing the tire. The tire may be
removed from the rim by turning it over and follow­
ing the procedure in step 4.
