Multiquip EE44774 Tire/Wheel Assembly ST225/75D-15 L/R "D" 6-Lug 2,540 Lbs

The Multiquip EE44774 is a genuine OEM Tire/Wheel Assembly ST225/75D-15 L/R "D" 6-Lug rated at 2,540 lbs, designed for Multiquip trailer models including TRLR45H, TRLR45E, TRLR502XFH, TRLR502XFE, TRLRSG1600XFH, TRLRSG1600XFE, and TRAILER series equipment. As a direct OEM replacement sourced through Multiquip's authorized parts network, EE44774 delivers the exact size, load rating, and bolt pattern your trailer requires. This assembly ships as a complete unit — tire and wheel together — so you can get your trailer back in service without sourcing components separately. Verify your trailer model against the fitment list before ordering to confirm compatibility.

Key Features

• ST225/75D-15 Load Range D Rating — Built to a 2,540 lb load capacity per wheel, matched to the rated towing capacity of Multiquip trailer models in this series.
• 6-Lug Bolt Pattern — Mounts directly to the OEM hub on compatible Multiquip trailers; no drilling, re-drilling, or adapter hardware needed.
• Complete Tire and Wheel Assembly — Supplied as a ready-to-mount unit, eliminating the need to source tire and rim separately and speeding up replacement in the field.
• Broad Trailer Series Fitment — Confirmed for TRLR45H, TRLR45E, TRLR502XFH, TRLR502XFE, TRLRSG1600XFH, TRLRSG1600XFE, and TRAILER series; verify your model code before ordering.
• Genuine OEM Component — Manufactured to Multiquip's original specifications, ensuring the tire size, load index, and wheel dimensions match what the trailer was engineered to run on.
• Trailer Stability Under Load — A correctly rated and properly inflated trailer tire maintains stable tracking and braking performance when hauling heavy construction equipment; an underrated or worn tire risks blowout and loss of control.

A trailer tire and wheel assembly carries the full static and dynamic load of whatever equipment is being transported, transmitting weight from the trailer frame to the road surface through the tire sidewall and tread. The ST (Special Trailer) designation on the ST225/75D-15 means the tire is engineered specifically for towed trailer applications, with stiffer sidewalls than passenger or light-truck tires to resist the lateral forces generated during cornering and lane changes under load. When a trailer tire reaches the end of its service life — through tread wear, sidewall cracking, or impact damage — it should be replaced with an assembly that matches the original size and load range exactly; substituting an underrated tire on a loaded construction equipment trailer creates a genuine safety hazard on public roads.
