Goodyear Flight Mate Butyl Inner Tube 8.50-6 TR-25 S
Available now on the Airparts.aero Marketplace.
Overview
The Goodyear Flight Mate is a premium-quality aircraft tire inner tube, engineered for the demanding environment of general aviation, particularly for aircraft operating with large, low-pressure 8.50-6 tires. This is a flight-critical component manufactured from a specialized butyl rubber compound, designed to provide exceptional air retention and a long, reliable service life. This specific model features a TR-25 bent valve stem, an essential feature for wheel assemblies where a straight valve would be inaccessible. As a genuine Goodyear product, it guarantees the quality and durability required for both on and off-airport operations.
Key Features
Superior Butyl Rubber Compound: Manufactured from a high-grade butyl rubber (isobutylene-isoprene rubber). This material has an extremely low permeability to air, providing superior air retention compared to natural rubber. This means the tire maintains its correct pressure for longer, a critical feature for backcountry and STOL aircraft.
TR-25 Bent Valve Stem: Equipped with a TR-25 valve stem, which is bent at a 90-degree angle. This design is essential for many aircraft wheel halves, ensuring the valve is accessible for inflation and pressure checks without interfering with brake components or the wheel structure.
Excellent Durability & Puncture Resistance: The butyl compound is formulated to be highly durable and resistant to punctures and tearing. It maintains its integrity at the wide range of operating temperatures encountered in aviation.
Balanced for Smooth Operation: Manufactured using a process that ensures a consistent and uniform thickness. This is critical for maintaining the balance of the entire wheel and tire assembly, preventing vibration and shimmy, especially in tailwheel aircraft.
Genuine Goodyear Quality: As a genuine factory component from Goodyear, a world leader in tire technology, it guarantees the correct material composition, valve stem specification, and quality control required for a safe and airworthy installation.

Applications
This Goodyear inner tube is the essential component for tire inflation and pressure retention in demanding applications:
Tire Installation: The primary air-holding chamber within an 8.50-6 tube-type tire assembly.
Backcountry & Off-Airport Operations: The robust butyl construction is ideal for the rigors of landing on grass, gravel, and other unimproved surfaces.
Maintenance & Repair: A mandatory replacement item whenever a new tire is installed on a tube-type wheel to ensure the entire assembly is fresh and reliable.
Why Choose Goodyear Flight Mate?
Proper tire pressure is a critical safety-of-flight issue, especially for tailwheel aircraft where ground handling is demanding. A slow leak or a catastrophic failure of an inner tube can lead to tire failure during the most critical phases of flight. Using a genuine Goodyear inner tube is the only way to ensure you are installing a component made from a certified, aviation-grade butyl compound with a properly vulcanized, high-pressure valve stem. For the safety and reliability of your landing gear, there is no substitute for a genuine OEM tube.

The selection of butyl rubber for the Goodyear Flight Mate inner tube is a key engineering choice. Butyl is a synthetic polymer with a very low gas permeability, approximately 8-10 times lower than natural rubber. This molecular density is what allows a high-pressure aircraft tire to maintain its pressure for extended periods. The TR-25 bent valve stem is a critical feature for many split-rim wheel designs where the deep recess of the inboard wheel half makes a straight valve stem impossible to access once the wheel is assembled. The 90-degree bend ensures the valve is accessible through the opening in the wheel for easy servicing.
Note: This is a flight-critical component. Tire mounting and installation must be performed by a certified A&P mechanic in a safe environment, typically using a tire inflation cage. Always dust the inner tube and the inside of the tire with talc before installation to prevent chafing. Inflate with dry nitrogen to the pressure specified in the Aircraft Flight Manual or POH.
