Firestone 938661 20-Inch Radial Tire Flap for Split Rim Wheels

The Firestone 938661 is a high-quality 20-inch radial tire flap designed for use with split rim and multi-piece wheels commonly found on medium-duty trucks, box trailers, and commercial vehicles. This flap provides essential protection for inner tubes by creating a barrier between the tube and the metal rim components.

Key Features:

• Radial flap construction suitable for both radial and bias ply tires
• Center valve hole placement for proper tube installation
• Protects inner tubes from rim wear, heat buildup, and sharp metal edges
• Extends inner tube service life by preventing punctures and abrasion damage
• Manufactured by Firestone to meet commercial vehicle standards

Compatibility:

This 20-inch flap fits the following tire sizes: 7.50-20, 7.50R20, 8.25-20, 8.25R20, 9.00-20, and 9.00R20. The flap is designed specifically for split ring and multi-piece wheels that require disassembly for tire removal and installation.

Application:

Essential for tube-type tire installations on medium-duty trucks and commercial vehicles equipped with split rim wheels. The flap acts as a protective liner that prevents tube failure caused by contact with rim components, lock rings, and other metal surfaces inside the wheel assembly.
