The ROBINSON MT936-8 is an inner tube designed for small aircraft ground handling wheels used on Robinson helicopter landing gear assemblies and related ground support wheel configurations. The sizing 2.80–2.50 × 4 indicates compatibility with 4-inch rim aircraft utility wheels commonly used on helicopter ground handling gear, training wheels, and tug/tow applications.

This tube is built for low-speed, high-load static and taxi operations rather than high-speed automotive use. It provides air retention and structural support inside a bias-ply aircraft tire, ensuring proper load distribution during ground handling, parking, and towing operations of light helicopters.

The MT936-8 designation is often associated with aviation-specific tubing variants used in OEM or replacement wheel assemblies where durability, vibration resistance, and slow-leak performance are critical.
