The Genie 77791GT is a genuine OEM Left-Hand Tire & Wheel Assembly designed for Genie S-series telescopic boom lifts and Z-series articulating boom lifts. Sourced directly from Genie, this assembly delivers the exact 355/55D625 flat-free tire and wheel specification required by the machines it serves — no guesswork, no substitution. Compatible models include the S-60, S-65, S-80 J, S-60 XC, S-65 XC, S-60 TRAX, S-65 TRAX, Z-60/34, Z-62/40, and related DC, FE Hybrid, HC, and HF variants, making this assembly the correct left-hand replacement across a wide range of Genie boom lift configurations.
Key Features
- OEM-Matched Flat-Free Construction — The 355/55D625 flat-free (FF) tire eliminates pneumatic blowout risk and matches the original specification for zero-compromise load handling.
- Correct-Side Fitment — Designated as the left-hand (LH) assembly, this unit mounts directly to the LH drive position without modification, preserving the machine's axle geometry and steering alignment.
- Broad S and Z Boom Compatibility — Fits a wide range of Genie telescopic and articulating boom lifts, including S-60, S-65, S-60 XC, S-65 XC, S-60 TRAX, S-65 TRAX, Z-60/34, Z-62/40, and multiple DC, FE Hybrid, HF, and HC variants.
- Genuine Genie OEM Quality — Manufactured to the same tolerances and load ratings as the original assembly, ensuring the wheel and tire perform as the machine was engineered to expect under full-rated platform loads.
- Traction and Stability at Height — A worn or damaged drive tire compromises grip, drive balance, and level positioning on rough or uneven surfaces — replacing with this assembly restores the machine's intended ground-contact performance.
- Critical Safety Component — On aerial boom lifts operating at height, drive-wheel integrity directly affects machine stability and safe travel. Using the correct OEM tire and wheel assembly supports compliance with Genie's service requirements.
The tire and wheel assembly is a combined drive component that supports the machine's weight, transmits drive force to the ground, and contributes to stable positioning during both travel and elevated operation. On boom lifts, where platform height amplifies any instability at ground level, proper tire condition and correct wheel fitment are essential to safe, controlled machine movement. A flat-free tire of this type is designed to carry its rated load without air pressure, eliminating the risk of sudden deflation — but when the tire or wheel becomes cracked, worn, or damaged, traction and load distribution suffer, increasing the risk of drive imbalance or tip hazard. Replacing the left-hand assembly with part number 77791GT restores the machine to its original ground-contact specification and keeps the drive system symmetrical across both sides.
