The Genie 50188GT is a genuine OEM Tire & Wheel Assembly designed for Genie S-120 and S-125 telescopic boom lifts and the Z-135/70 articulating boom lift. As a factory-sourced assembly, this part meets the exact specifications Genie engineers built these machines to run on, ensuring the wheel and tire unit interfaces correctly with the axle, hub, and drive system. Cross-reference part number 50188GT against your parts manual to confirm the right-front or right-rear position fitment before ordering.
Key Features
- Factory-Matched Construction — Sourced directly from Genie as a genuine OEM assembly, the tire and wheel are pre-mounted and matched to the load ratings and dimensional tolerances required by these large-capacity boom lifts.
- Direct Hub Fitment — The assembly is engineered to mount directly to the hub on S-120, S-125, and Z-135/70 machines, with correct bolt-circle and offset dimensions that align to the existing axle hardware without modification.
- Multi-Platform Compatibility — Fits Genie's largest telescopic boom lifts (S-120, S-125) and the high-reach Z-135/70 articulating boom, covering key models in the heavy-duty aerial work fleet.
- Traction and Stability Under Load — A correctly fitted tire and wheel assembly maintains the ground contact and load distribution these machines depend on when operating at full height and reach. A worn, damaged, or improperly spec'd replacement can compromise stability and steering response.
- Structural Integrity for Elevated Operations — On boom lifts operating at extreme heights, tire and wheel integrity is directly tied to platform stability and safe machine travel. Using the correct OEM assembly supports the structural performance the machine was rated for.
The tire and wheel assembly serves as the primary interface between the machine and the ground, bearing the full weight of the boom lift while enabling both travel and stable positioning during elevated work. On large boom lifts like the S-120, S-125, and Z-135/70, the assembly must handle significant static and dynamic loads — a compromised tire or wheel can cause uneven ground bearing, abnormal drive behavior, or instability during boom extension. Replacing a damaged unit with the correct OEM assembly restores proper load distribution, traction, and the drive characteristics these machines were built to deliver.
