265F86-8 – Goodyear Flight Custom III 22 x 6.75-10 8-Ply Tubeless Aircraft Tire

Available now on the Airparts.aero Marketplace.

The Goodyear 265F86-8 (Manufacturer Part Number 301-393-005) is a high-performance, tubeless (TL) aircraft tire from the esteemed Flight Custom III product line. Designed specifically for the demanding ground-operational cycles of corporate jets and high-performance turboprops, this 8-ply rated tire is engineered to provide the highest level of durability in the general aviation market. The 265F86-8 represents a significant advancement in elastomeric engineering, featuring a Kevlar®-reinforced belt package that stabilizes the tread area to provide more landings per tire change and enhanced resistance to punctures.

Rated for speeds up to 160 MPH, the 265F86-8 is built to handle the high kinetic energy of landing impacts and the centrifugal stresses of high-speed takeoff rolls. The Flight Custom III’s proprietary dual-polymer tread compound and deep-groove rib design provide superior wet-runway traction and consistent braking performance. For operators of performance-class aircraft, this tire is the gold standard for reducing long-term maintenance costs while ensuring the highest margins of safety during critical phases of flight.

Key Features

• Kevlar® Reinforced Belt: An integrated belt made of DuPont™ Kevlar® fiber stabilizes the tread face, significantly reducing "tread squirm" and extending the service life of the tire.

• Dual-Polymer Tread Compound: A specialized blend of synthetic and natural rubbers optimized for high-abrasion resistance and superior grip on both dry and wet pavement.

• 8-Ply Rated Carcass: Offers an optimized strength-to-weight ratio, providing the necessary structural integrity for medium-weight airframes without excessive weight penalties.

• High-Efficiency Hydroplaning Resistance: Features extra-deep circumferential grooves designed to channel water away from the contact patch, maintaining traction on contaminated runways.

• Advanced Tubeless Liner: Utilizes a specialized inner liner to ensure air-tight integrity, eliminating the friction and heat generation associated with tube-type assemblies.

Applications

The 265F86-8 is a Main Landing Gear (MLG) tire. Its primary function is to support the aircraft's weight during ground operations and to dissipate the massive energy of landing. It is engineered for high-cycle environments where consistent braking performance and lateral stability are paramount.

Why Choose 265F86-8?

Choosing the Goodyear Flight Custom III 265F86-8 ensures your flight department benefits from the lowest "cost-per-landing" in the industry. The inclusion of Kevlar® reinforcement sets this tire apart from standard bias-ply competitors by providing an extra layer of protection against foreign object debris (FOD) and ensuring even tread wear throughout the tire's life. When safety and dispatch reliability are non-negotiable, the 265F86-8 delivers the performance required for high-speed jet operations.

The engineering of the Goodyear 265F86-8 focuses on the management of viscoelastic hysteresis and centrifugal growth. In high-speed jet applications (160 MPH), tires are prone to "growth," where centrifugal force expands the tire's diameter, leading to increased heat and potential wheel-well interference. The Kevlar® belt in the Flight Custom III acts as a circumferential constraint, significantly reducing this expansion and maintaining the tire’s geometric stability. The 8-ply carcass uses a bias-ply architecture with high-tenacity nylon cords laid at specific angles to optimize the anisotropic load-carrying capability. This design allows for controlled sidewall deflection to absorb landing shocks while the belt ensures a stable, high-friction contact patch. Furthermore, the tubeless liner is composed of a halobutyl rubber compound with extremely low gas permeability, preventing the oxidative degradation of the internal carcass cords by maintaining an inert internal environment.

Note: This is a flight-critical, life-limited component. This tire must be mounted on a wheel assembly specifically certified for tubeless operation. During installation, the wheel O-ring must be replaced, and the inflation valve must be inspected for integrity. Installation must be performed by a certified A&P mechanic in accordance with the Goodyear Aircraft Tire Care & Maintenance Manual and the specific Airframe Maintenance Manual (AMM). Proper inflation pressure is the most critical factor in tire longevity and safety; always use a calibrated pressure gauge.
