Includes bearings for 8mm axles. Fills with standard hand pump (same as bicycle/car valve). Ideal for larger models up to 25kg (55lbs) take off weight.

• The wheels are delivered with reduced air pressure! Please inflate according to the following instructions!
• Before delivering the wheels we fill them with our sealant. If a sealant has leaked visibly, please send photos to us and do not mount the wheel.
• Pumping up the wheel is only allowed by a manual pump. Never use a compressor! Otherwise the wheel may burst
• In order not to move the valve too much mechanically during inflation, please use only a pump with a hose for plugging on, never for screwing on! Otherwise the entire valve may loosen prematurely and thus cause premature air leakage.
  
• If the valve body has loosened in the jacket, it can be reglued with superglue.
  
• In addition, please unscrew the valve cover (dust cap) only slightly so that the valve body is not loosened.
  
• Minimum pressure 0.4 bar. Please use a pressure manometer.
  
• Maximum pressure 0.6 bar. Please use a pressure manometer.
• Recommended operating pressure: Inflate the wheel with a manual pump until the wheel can be pressed in with your thumb about 20-30 mm. (approx. 0.45 bar)
• Caution: Some pressure manometers on air pumps are too inaccurate. Please make sure that the pressure manometer is working properly. We recommend digital pressure manometers that respond from an air pressure of 0.15 bar.
• In order to avoid flat or damaged wheels never store the model on them for an extended period.
  
• In case of large temperature fluctuations (e. g. from the "cold" basement to the "hot" car) it is recommended to carry the pressure manometer and the manual pump with you in order to be able to adjust the pressure.
• Attention: If the pressure is too high and the heat is too high, e. g. in a car, the wheels may be damaged or even burst.
• If the air durability of the tyres deteriorates noticeably, even after repeated inflation, you are welcome to contact us. We will gladly send you an offer for repair.
• Please note that 8mm axles are recommended and that our 6mm diameter ball bearings may only be used on light models.
  
• Basically, there is no cleaning required for The tires. If you would like to clean your tires, we recommend to do this with water and, if necessary, some detergent. Further care measures are not required.
  
• Here some practical examples how the wheels can be relieved during storage: Hang up the model aircraft; jack up the axles or the landing gear with spacer blocks or cut tyre protectors from e. g. Styrodur
• If you need spare parts for your wheels, please feel free to contact us.
