Airlines, aerospace and defense companies are using aircraft tire racks to store their tires.
Many specific guidelines must be followed when storing aircraft tires. Ideally, both new and retreaded tires should be stored in a cool, dry place out of direct sunlight. Temperatures should be between 32°F (0°C) and 85°F (30°C). Particular care should be taken to store tires away from fluorescent lights, electric motors, battery chargers, electric welding equipment, electric generators and similar equipment.
Care should be taken that tires do not come in contact with oil, gasoline, jet fuel, hydraulic fluids or similar hydrocarbons. The biggest danger for any aircraft tire is that it does not stand or lay on the floor where these contaminants are often found. For this reason whenever possible aircraft tires should be stored vertically on tire racks inside of a dark warehouse. The surface of the tire rack against which the weight of the tire rests should be flat and wide to minimize distortion.
Another way to store aircraft tires is stacking the tires horizontal on a stack rack. However, care must be used to prevent distortion of the tires on the bottom of the stack inside of the rack. Tires stored in racks, but leaning on the chine, can also cause distortion. The following is the maximum recommended stacking height of tires inside of an aircraft tire rack:
|Up to 40 inches||5|
|Over 40 inches to 49 inches||4|
|Over 49 inches||3|
In short, aircraft tire racks are a necessity for companies to ensure that tires don't get damaged and will be safe to use in the future.
