Multiquip 3N42014 Tire and Wheel ST225/75R 15

The Multiquip 3N42014 is a genuine OEM Tire and Wheel ST225/75R 15 designed for DCA-125US and ST225 ultra-silent generator units. As a direct OEM replacement, this assembly is sourced and specified by Multiquip to match the original component, ensuring the correct load rating, rim dimensions, and fitment for trailer-mounted generator applications. Verify your model code against DCA-125US and ST225 before ordering to confirm compatibility.

Key Features

• OEM-Matched Tire and Wheel Assembly — Manufactured to the same ST225/75R 15 specification as the original, ensuring the correct load range and rim fitment for generator trailer service.
• Direct Replacement for DCA-125US and ST225 — Engineered to bolt on in place of the factory assembly with no adaptation, maintaining the original axle and hub interface.
• Correct Load Rating for Generator Trailer Use — The ST (Special Trailer) sizing designation is rated for the sustained static and dynamic loads typical of towed generator equipment, reducing the risk of tire failure under load.
• Maintains Towing Stability — A properly sized and inflated tire and wheel assembly keeps the trailer tracking true at road speed; mismatched or worn tires compromise stability and handling.
• Genuine Multiquip OEM Part — Supplied under Multiquip part number 3N42014, ensuring you receive the correct assembly without guesswork on sizing or compatibility.

The tire and wheel assembly on a trailer-mounted generator carries the full static weight of the unit at rest and absorbs dynamic loads during transport. A correctly rated ST-series tire is built for these sustained loads, unlike passenger or light-truck tires that can overheat and fail under constant trailer stress. When this assembly wears, develops sidewall damage, or loses structural integrity, it creates a towing hazard and must be replaced promptly to keep the generator road-legal and safe to transport.
