GOODYEAR® Flight Eagle® Tire Without Deflector

With over 100 years of brighter ideas about lighter flight, it’s only natural that Goodyear lights the way with LJs and VLJs.
Goodyear Flight Eagle LT is a new tire, but it’s already been chosen for the Embraer Phenom 100 and Phenom 300 aircraft. The LT stands for Light Turbine… a new generation of aircraft tires for demanding high speed take-offs and landings.
Goodyear Flight Eagle tires are the industry’s preferred business jet tire.

Overview

The Goodyear® 185F03-5 is a high-performance, bias-ply aircraft tire from the prestigious Flight Eagle® series, specifically engineered for the nose landing gear of high-speed business and corporate jets. This tire is a testament to advanced aerospace engineering, featuring a robust 10-ply rating, a 210 MPH speed rating, and, most critically, an integrated chine sidewall. The chine is a specially profiled deflector ridge on the tire's sidewall designed to redirect water and slush away from the aircraft's sensitive, fuselage-mounted engine inlets during operations on contaminated runways. This feature is a critical safety system to prevent engine compressor stall or flameout due to water ingestion.

The tire's construction utilizes a durable, fatigue-resistant nylon cord casing laid in a proven bias-ply configuration to provide the strength and stability required for high-speed operations. Goodyear's advanced tread compounds are formulated for exceptional wear life and superior traction. As a TSO-certified component, the 185F03-5 Flight Eagle® represents the pinnacle of safety, reliability, and performance for corporate jet nose wheel applications.

Key Features

• Integrated Chine Sidewall: A built-in hydrodynamic deflector that channels water and slush spray laterally, providing critical protection for engine inlets during ground operations on contaminated surfaces.

• High-Speed 210 MPH Rating: Certified for the high ground speeds encountered during takeoff and landing by modern high-performance business jets.

• Robust 10-Ply Rating: An index of a high load-carrying capacity, providing a strong, durable casing resistant to punctures and foreign object damage (FOD).

• Durable Nylon Casing: Constructed with multiple layers of high-strength nylon cords to provide excellent dimensional stability and resistance to centrifugal forces at high speeds.

• Optimized Tread Compound: Utilizes Goodyear's advanced rubber compounds for long tread life and excellent runway traction.

• TSO Certified: Manufactured and tested in strict accordance with FAA TSO-C62 requirements, ensuring the highest level of aviation safety and quality.

Why Choose 185F03-5?

Choosing the Goodyear® 185F03-5 is an investment in a critical, OEM-certified safety system. For aircraft with low-slung engines, the risk of engine flameout from water ingestion on a wet runway is significant. The engineered chine on this tire is a primary defense against such an event. Using a non-chine or unapproved tire compromises this vital safety feature and violates the aircraft's type certificate. Furthermore, Goodyear's reputation for quality ensures that the tire will perform reliably under the extreme loads and speeds of takeoff and landing, providing excellent service life and the margin of safety required for corporate aviation.

The engineering principle behind the 185F03-5's integrated chine is rooted in fluid dynamics. As the tire rolls through standing water at high velocity, a hydrodynamic wave is created. Without a chine, this spray is projected upwards and outwards in a wide, uncontrolled fan pattern. The chine, a precisely angled and molded ridge on the upper sidewall, intercepts this high-velocity spray at its point of origin. It acts as a hydrodynamic weir and deflector, altering the spray's momentum vector. This redirects the sheet of water and slush into a controlled, low-trajectory lateral path, well clear of the engine inlet's zone of influence. This is a critical design feature for preventing engine water ingestion, which can lead to compressor stall or flameout during the critical takeoff roll or landing rollout phases of flight.

Note: The 185F03-5 is a flight-critical component. It must be installed by a certified A&P mechanic in strict accordance with the aircraft and component maintenance manuals. Proper inflation with dry nitrogen is absolutely critical for performance and safety and must be checked prior to the first flight of the day. This is a nose-wheel-specific tire and should not be used in a main wheel position.
