Note
• Always use new valves when changing tyres! Steel valves (part no. 993.361.073.00) −1− are used for
18−inch Turbo II wheels and rubber valves −2− for 18−inch Turbo−Look II wheels. Steel valve
assembly ' 443519 Removing and installing valve (steel valve).
• When fitting tyres, the direction of rotation and the inner and outer sides should be noted!
• Use only TIP TOP Universal, order No. 593 0601 (3.5 kg bucket) or Contifix as the mounting paste!
When mounting tubeless tyres, check the sealing surface of the tyre and the disc wheel for cleanliness and any
signs of damage. Bear in mind here that the bead base performs the sealing function on tubeless tyres. If the
bead edge has to perform the sealing function, air can escape when the vehicle is driven aggressively.
When mounting the tyre beads, use only the prescribed tyre mounting pastes. The following can occur if an
unsuitable mounting paste is used:
• twisting of the tyre on the rim,
• fracture of the bead core during mounting,
• damage to the rim surface by aggressive substances.
If Contifix is used, apply sparingly to the tyre beads (due to risk of the tyre turning on the wheel). If possible,
the vehicle should not be driven for 24 hours after tyre mounting or matching.
