Tire Maintenance Instructions
• Maintain stipulated air pressure, check at regular intervals!
Underpressure results in reduced load capacity and shortens service life.
• Inspect tires at regular intervals for damages, shredding, flat areas and foreign objects.
• Wheel units must be mounted perfectly balanced. Wheel imbalance can result in a damage to bearings and brake drums.
• Keep tires free of oil, grease, brake fluid and tar. Clean tires with rag soaked with petrol, then wash off with soap and water.

TOST Notes on Inner Tubes
Aircraft tubes are made from natural rubber and they are slightly underdimensioned so that it is easier to install them in a new tire. The layers of an aircraft tire are made of nylon – they therefore tend to become larger with use.
The inner tube also increases in size, adapting to the larger inside diameter of the tire. If a tube enlarged in this way is later fitted in a new tire, it can happen that it is too big for the inside of the tire, with the result that the tube may crease. These creases may rub through during operation, causing the tube to loose pressure. Rubbing through slowly results in slow pressure loss – the pilot is thus warned before a dangerous situation arises. If the tube tears during a start, the pilot will fail to notice that he is flying with a flat tire.
Taking into consideration all the risks involved with fitting an old tube into a new tire, it is advisable always to fit new inner tubes in new tires.
