The Genie 99589GT is a genuine OEM Euro Tire/Wheel Assembly designed for TZ-50 and TMZ-50/30 trailer-mounted articulating boom lifts.

It is confirmed to fit the TZ-50 and TMZ-50/30, making part number 99589GT the straightforward solution when your trailer boom needs a wheel assembly replacement. Cross-reference 99589GT against your parts manual to verify the correct application for your unit before ordering.
Key Features
- Genuine OEM Construction — Manufactured to Genie's original design tolerances, ensuring the tire compound, wheel dimensions, and load rating match what came on the machine from the factory.
- Complete Drop-In Assembly — Supplied as a ready-to-mount tire and wheel unit, so installation goes straight on without sourcing individual components separately.
- Confirmed Fitment for TZ and TMZ Trailer Booms — Fits the TZ-50 and TMZ-50/30 trailer-mounted articulating boom lifts, covering both tow-behind boom lift platforms in the Genie trailer boom range.
- Tow and Transport Integrity — A correctly rated and properly seated wheel assembly keeps the trailer boom tracking true and stable during road transport — a worn or damaged assembly can compromise towing handling and machine positioning on site.
- Towable Boom Safety Compliance — On trailer-mounted booms, wheel assembly condition directly affects road-legal towing and safe machine deployment; replacing a failed assembly with the OEM-specified part supports compliance with towing and transport requirements.
The tire/wheel assembly on a trailer-mounted boom lift serves as both a road-transport component and a critical structural element during equipment positioning. It carries the full weight of the machine during towing and must maintain correct load capacity, inflation characteristics, and wheel-to-axle fitment to keep the trailer tracking safely. When a tire wears unevenly, the wheel is damaged, or the assembly no longer seats correctly on the hub, it can affect towing stability, cause uneven loading on the axle, and prevent the boom from being accurately positioned at the work site. Replacing the assembly promptly with the correct OEM part restores safe towing capability and keeps the trailer boom ready for deployment.
