Free the wheel from the abraded rubber particles and check for damage.
A new valve must always be fitted. Steel valves -1- are used for 18-inch Turbo II wheels and rubber valves -2- for 18-inch Turbo-Look II wheels. See Fig 2.

Coat the wheel and tire with tire mounting paste - TIP TOP Universal, order No. 593 0601 - or Contifix.
Place the tire in the correct position on the wheel. Push in mounting arm and position on top of the rim flange.
Guide the tire bead through the assembly head. Fit the tire bead in the deep bed by turning the wheel to the right.

At the start of the mounting process of the second tire bead, the mounting arm should be positioned opposite to the valve. This prevents damage to the valve.
Press the second tire bead onto the wheel as flat as possible and guide through the assembly head.
Insert first holding-down device and position the second holding-down device offset by 90° to 120°. Fit tire bead in deep bed by turning to the right.

Fill tire with compressed air. At approx. 4.0 bar, the beads should pop over the hump. Coat the tire beads with mounting paste again if necessary so that they can pop over easily and gently.
