The Multiquip TWM225 Tire Wheel Assembly 85/125 ST22575R15 is a genuine OEM replacement designed for the ST225 water trailer. This factory-matched assembly ships as a complete unit — tire and wheel together — so it bolts directly onto your ST225 without the need to source components separately. As a genuine Multiquip OEM part, it meets the exact size, load rating, and mounting specifications the ST225 was engineered around, keeping your trailer road-legal and properly balanced under load. Confirm your model code is ST225 before ordering to ensure a correct, worry-free fit.

Key Features

  • OEM-Matched Tire and Wheel Spec — Genuine Multiquip OEM construction ensures the ST22575R15 tire size and wheel dimensions match the original ST225 design exactly, maintaining correct load capacity and road handling characteristics.
  • Complete Assembly for Direct Installation — Supplied as a fully assembled tire-and-wheel unit, this part installs as a straight swap onto the ST225 hub — no separate mounting or sourcing of individual components required.
  • Built for ST225 Water Trailer Compatibility — Engineered specifically for the ST225 series, this assembly accounts for the trailer's gross vehicle weight rating and axle load demands in towing applications.
  • Maintains Safe Towing Performance — A correctly sized and rated tire-wheel assembly is essential for stable trailer tracking and braking response; an out-of-spec or worn tire increases sway risk and uneven load distribution on the road.
  • Road Safety Critical Component — Trailer tires operate under sustained highway loads and heat cycles; using the OEM-specified TWM225 assembly ensures the ST225 remains within its rated towing safety envelope.

The tire and wheel assembly is the primary contact point between your water trailer and the road surface. It bears the full static and dynamic load of a filled tank during transport, and an undersized or mismatched tire can lead to overheating, blowouts, or loss of directional stability at highway speeds. On a water trailer like the ST225, where payload weight shifts with water movement, a properly rated OEM assembly like the part is essential to keeping the trailer tracking predictably and safely from jobsite to jobsite.
