- Fully deflate the tyre, removing the valve (Fig. 14).
- Set the stroke end of the breaker arm (see Figure 15) to the
width of the rim. This will avoid (especially if you operate
on low profile tires and with the particularly cold side),
excessive stress, which can damage the tire.
- Position the wheel as shown in fig.15a and move the bead
breaking shoe near the rim edge.

around the entire circumference of the lower
