Available now on the Airparts.aero Marketplace.

Overview

The Goodyear® 185F88-6 is a high-performance, bias-ply aircraft tire engineered specifically for the main landing gear of the world's most popular light and mid-size business jets. This tire is a benchmark in aviation tire technology, offering a precisely optimized 8-ply rating and a 190 MPH speed rating to meet the specific performance and weight requirements of this aircraft category. It is designed to provide exceptional durability, superior traction, and long-lasting, reliable service under the demanding conditions of corporate and private jet operations.

The tire's construction features a robust and fatigue-resistant nylon cord casing, which provides the strength needed to handle the high loads of landing and the centrifugal forces of high-speed takeoffs. Goodyear's proprietary long-life tread compounds and tread design are formulated to resist wear and provide excellent grip on a variety of runway surfaces. As a fully TSO-certified component, the 185F88-6 is a premier choice for operators seeking to combine the highest levels of safety with economic operational value.

Key Features

• Optimized 8-Ply Rating: Specifically engineered for the load requirements of light-to-mid-size business jets, providing the necessary strength without the weight penalty of higher-rated tires.

• 190 MPH Speed Rating: Certified for the high ground speeds encountered by modern jet aircraft during takeoff and landing.

• Long-Life Tread Compound: Utilizes Goodyear's advanced rubber compounds and tread design to maximize service life and reduce operational costs.

• Durable Nylon Casing: The bias-ply construction with multiple layers of high-strength nylon cord provides a tough, resilient casing for enhanced safety and reliability.

• Superior Weather Resistance: Features specialized compounds in the sidewall to resist the degrading effects of ozone, UV light, and environmental exposure.

• TSO Certified: Manufactured and rigorously tested to meet or exceed the stringent safety and performance standards of FAA TSO-C62.

Why Choose 185F88-6?

Selecting an aircraft tire requires adherence to the specifications of the type certificate. The 185F88-6's 8-ply rating is not arbitrary; it is an engineered choice by the aircraft manufacturer to match the specific weight and performance characteristics of the airframe. Using an underrated tire is a catastrophic risk, while using an overrated tire adds unnecessary weight and can alter the tire's flex and ground handling characteristics. Choosing the genuine Goodyear® 185F88-6 ensures you are using a TSO-certified tire that meets the exact specifications for your aircraft, guaranteeing the highest margin of safety, reliability, and performance.

The engineering principle behind the 185F88-6's 8-ply rating is a critical optimization of the strength-to-weight ratio. The Ply Rating (PR) is a direct index of the tire's strength, which correlates to the maximum inflation pressure it can safely contain. This pressure, in turn, dictates the tire's maximum static and dynamic load capacity. For an aircraft in the Cessna Citation CJ class, an 8-ply rating allows for an inflation pressure that provides the precise load capacity required by the aircraft's maximum takeoff weight, with a mandated safety margin. Designing a tire with a higher ply rating would increase its weight with no operational benefit, thus reducing the aircraft's useful load. The 185F88-6 is a purpose-built solution, where the internal structure, material mass, and pressure containment capability are all precisely tuned to the specific mission profile and weight class of light business jets.

Note: The 185F88-6 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, safety, and tire life, and must be checked before the first flight of the day. This tire is typically used in a main wheel position.
