The Genie 121286GT is a genuine OEM RT LP Foam Left Tire & Wheel Assembly designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-80, S-80X, S-85, S-80 XC, S-85 XC, S-80 HF, S-85 HF, and Z-80/60. As a direct-from-Genie replacement, this assembly matches the original equipment specifications for the left-side rough-terrain position on these large-platform machines. The foam-filled construction eliminates the risk of flats and pressure loss, keeping these heavy-duty boom lifts moving reliably across uneven and demanding terrain without interruption.
Key Features
- Foam-Filled Flat-Free Construction — Solid LP foam fill permanently eliminates air pressure loss, blowouts, and flat-tire events that would otherwise ground a large boom lift mid-job.
- Genuine OEM Engineering — Sourced directly from Genie, this assembly is built to the exact load rating, rim diameter, and offset specifications required for correct fitment on the left rough-terrain wheel position.
- Broad S- and Z-Boom Compatibility — Fits the S-80X, S-80, S-85, S-80 XC, S-85 XC, S-80 HF, S-85 HF, and Z-80/60 — covering the full family of Genie large-platform boom lifts that share this wheel position.
- Ready-to-Mount Complete Assembly — Supplied as a fully assembled tire and wheel unit, so installation is straightforward — mount, torque, and return the machine to service without sourcing separate components.
- Rough-Terrain Traction Where It Counts — The RT tread pattern is engineered for the soft, uneven, and muddy ground conditions that large boom lifts routinely encounter, maintaining traction and stability at height.
- Stability and Safety on Large Booms — On machines operating at extreme heights, correct tire integrity directly affects platform stability and tip-load margins. A worn, damaged, or incorrect tire assembly on a large boom lift is a genuine operational hazard — replacing it with the correct OEM unit restores the margin the machine was designed to operate within.
A tire and wheel assembly on a rough-terrain boom lift does far more than simply support the machine's weight — it provides the traction, ground clearance, and lateral stability that allow the machine to travel and position safely on unpaved and uneven surfaces. On large boom lifts like the S-80 and Z-80/60 series, where the platform can extend to significant heights, the condition and specification of each wheel directly influences the machine's overall stability envelope. A foam-filled assembly removes the maintenance burden of monitoring air pressure and eliminates the sudden loss of support that a puncture or blowout can cause. When a tire assembly wears out or sustains damage, replacing it with the correct OEM part — matched to the right side, position, and rim specification — is essential to restoring the machine to its original safe operating condition.
