The Multiquip EE45318 Wheel Assembly ST175/80 D13 Load Rated is a genuine OEM component designed for the QP4TKT trash pump and GBX12SK and GBX24BK balloon systems. As a direct OEM replacement, EE45318 delivers the correct load rating, tire sizing, and hub fitment that Multiquip specifies for these units — no guesswork on compatibility. This wheel assembly is sourced directly through the Multiquip OEM parts program and sold by DHS Equipment to keep your equipment rolling with confidence. Whether you are returning a pump trailer to service after a flat or refreshing worn rolling stock on a balloon system, the EE45318 is the correct part for the job.
Key Features
- OEM-Specified Load Rating — ST175/80 D13 tire size and load rating match Multiquip's original design spec for safe towing and transport loads.
- Direct Bolt-On Replacement — Hub bore, bolt pattern, and overall assembly dimensions correspond directly to the OEM mounting points on compatible equipment.
- Broad Fitment Coverage — Confirmed fit for the QP4TKT trash pump, GBX12SK, and GBX24BK balloon systems.
- Maintains Safe Transport Performance — A correctly rated wheel assembly prevents trailer sway, uneven wear, and load-bearing failure during towing — critical for equipment moved frequently between jobsites.
- Genuine OEM Part — Sourced through the Multiquip OEM parts program, ensuring material grade, structural integrity, and assembly dimensions match the original component exactly.
The wheel assembly on a trailer-mounted or wheeled piece of equipment carries the full static and dynamic load of the machine during transport. The ST175/80 D13 designation indicates a special trailer tire rated for the specific load and speed requirements of towed equipment — not a standard passenger or light truck tire. When a wheel assembly wears out, cracks, or suffers a flat, the machine cannot be safely moved between sites. Replacing it with the correct load-rated OEM assembly restores safe transport capability and ensures the tire, rim, and hub work together as the original design intended.
