196K08-9 – Goodyear Flight Custom III Main Landing Gear (MLG) Tire
Available now through the AirParts Aero marketplace.
Overview Section
The Goodyear 196K08-9 is a premier Flight Custom III series aircraft tire, specifically engineered for high-performance turboprops and heavy twins. This tire is the industry standard for the Beechcraft 1900, King Air 300/350, and Baron 58P, offering a balance of high-speed durability and exceptional landing life.
The 19.5x6.75-8 sizing denotes a compact but high-load-bearing profile, essential for aircraft with retracted gear wells that have tight dimensional tolerances. Featuring a Rib (RIB) tread pattern and a 10-Ply Rating, the 196K08-9 is built with Goodyear’s proprietary Kevlar® carbon fiber reinforcement to provide superior stability and puncture resistance during high-speed takeoffs and landings on improved runways.
Key Features Section
Flight Custom III Technology: Goodyear’s top-tier general aviation tire, featuring deeper tread depth than standard tires for significantly more landings per wear cycle.
Kevlar® Belt Package: Enhanced with a Kevlar® reinforcement layer that improves tread-wear consistency and increases the tire's dimensional stability at high centrifugal speeds.
Aquachannel® Grooves: Precision-engineered longitudinal ribs provide excellent water displacement, reducing the risk of hydroplaning during wet-runway operations.
Dual-Polymer Compound: Utilizes a specialized tread compound that stays supple in freezing high-altitude temperatures while resisting "flat-spotting" during heavy braking.
High-Ply Rating (10-Ply): Offers the structural rigidity required for the high MTOW (Maximum Takeoff Weight) of the King Air 350 and Beech 1900D.
Ozone-Resistant Sidewall: Formulated with advanced antioxidants to prevent "weather checking" and sidewall cracking, extending the service life for aircraft parked in high-UV environments.

Aircraft Compatibility Section
The 196K08-9 is the primary Main Landing Gear (MLG) choice for several high-utilization airframes in the AirParts Aero inventory:
Beechcraft King Air: Standard MLG fitment for the Super King Air 300 and 350 series.
Beechcraft 1900: Critical for the 1900C and 1900D regional commuter fleets.
Beechcraft Baron: Specified for the pressurized 58P and 58TC variants.
Beechcraft Duke: The preferred high-load tire for the Model 60.
Military Trainers: Utilized on the T-34C Turbo Mentor.
Technical Applications & Safety
In high-performance twins like the King Air, the MLG tires are subject to intense side-loading during crosswind landings. The 196K08-9 is designed with a reinforced bead area to ensure the tire remains seated on the wheel rim during high-deflection maneuvers.
Safety Warning: Always check tire pressure "cold." For the 196K08-9, a 10% drop in pressure can lead to internal heat buildup and carcass delamination. Never exceed the speed rating of 160 MPH during ground rolls, and ensure the wheel’s thermal relief plugs are inspected if a high-energy rejected takeoff (RTO) occurs.
Technical Engineering Insight
The engineering value of the Goodyear 196K08-9 lies in its Carcass Fatigue Management. Unlike automotive tires, aircraft tires undergo massive deflection (up to 32%) during every landing. Goodyear engineers the 196K08-9 with an "over-built" carcass that limits "tread squirm," a phenomenon where the tread moves independently of the carcass, generating excess heat.
The 10-ply rating is not just about strength; it provides the specific spring rate required for the Beechcraft’s trailing-link landing gear to function as designed. By choosing the genuine Goodyear 196K08-9 through AirParts Aero, you ensure the tire's balance and roundness meet the strict tolerances required to prevent airframe vibration during high-speed taxi—vibration that can otherwise damage sensitive avionics and landing gear bushings.
Installation & Maintenance Addendum
Tube Compatibility: This is a Tube-Type tire. Ensure you use a high-quality Goodyear 19.5x6.75-8 tube to prevent "slow leaks" common with generic inner tubes.
Tread Wear: Tires should be removed for retreading when the wear reaches the bottom of any groove at any point on the tire.
Inflation Stabilization: After initial mounting and inflation, the tire should sit for 12–24 hours, then the pressure should be re-checked before installation on the aircraft, as the carcass will naturally expand slightly.
