Frequently asked questions

BeadBreaking

  • How to break the bead of radial tires?
    - Follow the procedure for radial tires! Request a copy by e-mail from spares(at)kunz-aircraft.com.
  • Is the use of lubricant applied to the bead seat of the rim helpful?
    - Yes, for radial tires, once the bead of the radial tire is broken! With a lubricant applied onto the rim seat the bead toe of the tire will slip easier. Do not apply lubricant to the tire side walls!
