112T06-3 - Goodyear 11.00-12 10PLY TL Type III Tubeless Rugged Rib Aircraft Tire 160 MPH

112T06-3 – Goodyear 11.00-12 10-Ply Tubeless Flight Leader Type III Rugged Rib Aircraft Tire

The Goodyear 112T06-3 is a flight-critical, high-performance Type III bias-ply tubeless main gear aircraft tire engineered to withstand the demanding mechanical stresses of rugged, unpaved runways and heavy utility operations. Featuring an 11.00-12 cross-sectional profile and a robust 10-ply rating, this tire is specifically optimized for high-load, short-takeoff-and-landing (STOL) airframes, regional turboprops, and specialized agricultural aircraft. Rated for ground speeds up to 160 MPH and an operational load capacity of 8,200 lbs, the 112T06-3 serves as the primary contact interface between the landing gear assembly and the runway surface, managing the extreme structural deceleration forces generated during touchdown.

Manufactured by Goodyear Aviation, a pioneer in elastomeric compound engineering, this bias-ply tire utilizes a specialized nylon cord body shape that reduces internal carcass fatigue as the tire cycles dynamically from tension to compression during taxi, takeoff, and landing phases. The premium "Rugged Rib" tread design incorporates deep circumferential grooves and a maximized ground contact footprint to balance uniform wear with superior braking traction across multi-surface operational environments—including concrete, asphalt, turf, and graded gravel. Its tubeless construction eliminates the internal friction and weight penalties associated with traditional tube assemblies, lowering wheel-well operating temperatures and simplifying maintenance workflows for fleet operators.

The Goodyear 112T06-3 represents the industry standard for tactical toughness and cyclic landing reliability. By incorporating high-modulus, triple-tempered nylon casing plies and advanced vulcanized rubber compounds, it provides maximum defense against foreign object debris (FOD) penetration, sidewall cracking, and tread shearing. For directors of maintenance, corporate flight departments, and aerial application operators, this tire delivers a long-lasting, FAA-TSO certified solution that lowers direct operating costs per landing while ensuring safety-of-flight integrity during demanding crosswind operations and high-energy maximum-braking events.

Key Features

• Dynamic Cord Body Geometry: Designed with a unique cord path that effectively dissipates structural stress concentrations as the carcass cycles from tension to compression under cyclic loading.

• Triple-Tempered Nylon Casing Plies: Constructed using high-tensile nylon cords that stabilize the tire's outer diameter against centrifugal growth at ground speeds up to 160 MPH.

• Specially Compounded Rugged Rib Tread: Formulated with a proprietary anti-ovalling rubber matrix that provides optimal cut resistance and uniform rib wear over hard and unpaved airstrips.

• Maximized Footprint Area: Features an expansive ground contact patch that optimizes braking coefficient efficiencies and prevents localized tread scrubbing.

• Advanced Integrated Inner Liner: Built with a specialized halobutyl compound lining that delivers exceptional inflation retention, eliminating the risk of inter-ply pressure blistering common to inferior casings.

Why Choose 112T06-3?

Selecting a genuine Goodyear 112T06-3 Flight Leader-class tire ensures that the aircraft's landing gear system operates safely within its certified kinetic energy parameters. Substandard or non-aviation commercial tires lack the rigorous TSO dynamic testing required to survive the high instantaneous acceleration and deflection rates experienced upon touchdown. Using a non-certified tire introduces a high risk of catastrophic carcass de-lamination or sudden bead unseating under heavy braking, which can collapse the landing gear leg, destroy structural wing spars, and lead to a complete loss of directional control. Goodyear’s stringent quality controls ensure optimal elastomeric cohesion, preserving cross-sectional dimensional stability across extreme temperature drops encountered during high-altitude cruise legs.

The performance mechanics of the Goodyear 112T06-3 turn on the principles of viscoelastic energy dissipation and anisotropic cord ply mechanics. Unlike radial designs, the bias-ply architecture of the 112T06-3 cross-lays alternate sheets of heavy-duty, triple-tempered nylon cords at specific acute angles relative to the centerline of the tread. This diagonal ply scheduling provides structural rigidity not just to the tread face, but across the entire sidewall profile, creating a balanced load-bearing truss that distributes impact energy evenly through the wheel rim during hard landings. When the tire meets the ground at ground speeds up to 160 MPH, it encounters an instantaneous angular acceleration phase known as spin-up, which induces high shear stress between the tread compound and the underlying carcass. The proprietary vulcanized rubber matrix of the rugged longitudinal ribs relies on short-chain cross-linked polymers engineered to resist reversion—the localized thermal breakdown of rubber molecules caused by extreme friction during heavy braking or sliding. Additionally, the integrated tubeless halobutyl liner seals directly against the wheel flange, forcing internal air inflation pressure to act as a direct structural fluid column that minimizes sidewall wrinkling and prevents bead chafing along the rim seat under severe lateral twisting loads.

Note: The Goodyear 112T06-3 is a flight-critical, high-energy landing gear component. Improper inflation, mounting damage, or structural over-loading can lead to sudden explosive tire failure during takeoff or landing rolls. Tire mounting, bead lubrication, and final balance adjustments must be performed exclusively by certified A&P mechanics or authorized repair stations using specific safety cages and calibrated inflation regulators in strict accordance with the Goodyear Aircraft Tire Care & Maintenance Manual and FAA Advisory Circular AC 20-97B. Always check for proper wheel rim sealing and replace the valve stem O-ring during every tire change sequence.
