QUESTIONS & ANSWERS
The Goodyear 302-246-400 Flight Mate Butyl Tube is an aircraft tire tube designed for tube-type aviation tires. Installed inside a pneumatic tire, it holds inflation pressure and supports proper tire performance during taxi, takeoff, and landing. Goodyear aircraft tubes are manufactured to meet SAE standard AS50141 for aviation use.
This aircraft tire tube features a 90° valve stem with a 3.25" length after the bend. The angled stem design allows easier access for inflation and pressure checks on compatible wheel assemblies. Proper stem length helps ensure a proper fit and convenient servicing.
Goodyear aircraft tubes do not have a fixed expiration date as long as they meet all service and inspection criteria. Airworthiness depends on proper storage, visual condition, and compliance with operator or maintenance program requirements. Tubes should always be inspected before installation, regardless of age.
It is strongly recommended to install a new tube when mounting a new tube-type aircraft tire. Tubes can expand up to 25% during service, taking a permanent set that makes them too large for reuse. Reinstalling a used tube may cause wrinkles, folds, or pinching, leading to failure or imbalance.
As a tube grows in service, its dimensions change permanently. If reused, the oversized tube may not seat properly inside a new tire, increasing the risk of creasing or structural damage. Using a new Goodyear butyl tube helps maintain safety, balance, and long-term performance.
Aircraft tire tubes should be stored in a cool, dry area between 32°F (0°C) and 85°F (30°C), away from direct sunlight. Whenever possible, keep tubes in their original cartons. If stored outside the carton, they should be lightly dusted with talc, wrapped in heavy paper, and never hung over nails or sharp objects that could cause creasing.
Yes, tubes may be stored inside matching tires if both are clean and lightly lubricated with talc. The tube should be inflated just enough to round it out without stretching. Proper storage helps preserve the integrity of rubber and prevents premature cracking.
Before mounting, carefully inspect the aircraft tube for cuts, cracks, or other damage. Inflate it only enough to round it out, as excessive inflation can strain splices and valve assemblies. The tube should never be inflated to a size larger than the tire during inspection.
Clean the inside of the tire and apply a light coating of talc before inserting the slightly inflated tube. Align the valve stem with the red balance dot on the tire to promote proper balance. When assembling the wheel halves, torque bolts according to the wheel manufacturer’s specifications before inflating the assembly.
After installation, a freshly mounted tube-type aircraft tire should be checked frequently during the first week of service. Air trapped between the tube and tire during mounting may gradually escape, leading to a temporary pressure loss. Monitoring inflation pressure before flights helps ensure safe and consistent aircraft tire performance.
