The Genie 77791GT is a genuine OEM Left-Hand Tire & Wheel Assembly, 355/55D625, FF built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-60, S-65, S-60 XC, S-60 HC, S-65 XC, S-80 J, Z-60/34, and Z-62/40. As a direct OEM replacement, this assembly ships ready to mount — no modification or separate sourcing of components required. Cross-reference part number 77791GT against your machine's parts manual to confirm it is the correct left-hand fitment for your unit.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original specifications, ensuring correct tire compound, wheel dimensions, and load rating for the machines this assembly serves.
- Correct Left-Hand Fitment — Supplied as a complete left-hand assembly with the 355/55D625 tire and wheel matched and ready to install on the correct side of the machine.
- Broad Boom Lift Compatibility — Fits a range of Genie S-series telescopic booms and Z-series articulating booms, including S-60, S-65, S-60 XC, S-65 XC, S-80 J, Z-60/34, and Z-62/40.
- Traction and Stability — A sound tire and wheel assembly keeps the machine tracking correctly on the ground, supporting safe travel and stable positioning on the job.
- Operational Safety — On boom lifts operating at height, a compromised tire or wheel can affect machine stability and travel control. Replacing a worn or damaged assembly with the correct OEM part restores the machine's ground interface to its designed condition.
A tire and wheel assembly combines the inflated tire and the wheel rim into a single, pre-matched unit mounted at each corner of the machine's drive chassis. On boom lifts like the S and Z series, these assemblies carry the full weight of the machine, support safe travel across the jobsite, and provide the grip needed for stable positioning before and during elevated operation. A cracked wheel, damaged bead, or worn tire can cause handling instability during drive and compromise the machine's level footing — both concerns that are best addressed with a correctly specified OEM replacement rather than a mismatched substitute. Because left- and right-hand assemblies are handed parts, confirming the correct side before ordering is essential.
