18.3. Breaking the lower bead
To break the lower bead, place the head just before the sensor. Pry the tire bead up
and over the head chisel, be careful not to hit the sensor. Slowly turn the wheel
clockwise until prying out the tire. Check sensor for damage.
18.4. Tire installation
Before installing the tires, check for the following:
•
Wheel rim must be in good condition, sensor and air valve must be in the
correct position.
•
Always replace valve insert, valve nut and O-ring.
•
Make sure wheel and tire match before mounting.
•
Clean the bead contact area on the wheel rim.
•
Lubricate the bead seat and both tire beads using suitable lubricant for touring
cars.
Strictly follow the tire manufacturer's recommendations to ensure the
rims you select are correct for the rim.
18.5. Seating the lower bead
Place the wheel rim on the tire changer, position it with the sensor at 9 o'clock and
lock the rim. Position the tire on the rim and move the head to its working position.
Place the bead over the rear end of the head and pry the tire into the wheel well. The
sensor should be safely positioned halfway between the seating area on the head and
the wheel rim. Slowly rotate the wheel until seating the bead.
