Overview

The FD425 is the super-single answer for fleets looking to cut weight, not capability. Running a 445/50R22.5 footprint, this wide-base drive tire replaces duals on the drive axle — one tire doing the work of two. It's part of the OptiGreen fuel-efficiency family and carries SmartWay verification.

Why This Tire Matters

Ditching duals for a super-single setup saves roughly 200 pounds per axle when you factor in the wheel. In weight-sensitive operations — bulk fuel haulers, tanker fleets, any carrier running near the 80,000-lb threshold — that weight comes straight back as additional payload. Multiply across a tractor-trailer, and the revenue upside is real. Our customers in South American agricultural corridors, where every kilo of soybeans counts, pay close attention to this math.

Key Features

• Wide-Base Single Tire Design — One 445/50R22.5 replaces two standard drive tires. Beyond the weight savings, you're buying half the tires at replacement time and carrying fewer spares on the road.
• EPA SmartWay-Verified Low Rolling Resistance — The fuel-efficiency certification means this super-single isn't trading rolling resistance for width. It meets the same benchmarks as the narrower OptiGreen siblings.
• High Load Capacity — 10,200 lbs Single — Load Range L construction handles the concentrated weight that comes with super-single applications. This isn't a light-duty tire pretending to be heavy.
• Multi-Service Capability — While most super-singles stay on the highway, the FD425 handles regional and intermodal work. The tread compound balances heat resistance with wear life across different speed ranges.

Best For

Bulk commodity haulers maximizing payload; tanker fleets running near weight limits; intermodal chassis operations looking to simplify inventory; any fleet converting from duals to wide-base singles for fuel and weight savings.
