Freedom Hauler Dutymax (All Steel) Tires

The Freedom Hauler Dutymax is an all-steel, all-season trailer tire built for heavy commercial trailer service. It is rated for trailers only and is not approved for light trucks or passenger vehicles.

The all-steel construction is the reason to step up to this tire. Steel in both the sidewall and the tread raises load-carrying capacity, limits sidewall flex when the trailer is loaded to its rating, and produces a casing that runs cooler over long hauls. That is a direct answer to the failure mode commercial haulers actually face, which is a heat-driven blowout on a hot highway rather than a tire wearing out its tread.

A stable center rib combined with a closed shoulder rib maintains continuous road contact, distributing pressure evenly across the footprint to support longer service life and lower rolling resistance. Four wide circumferential grooves clear water and slush, while multiple sipes add wet grip and dissipate heat from the contact patch.

If you are moving to all-steel because you have had failures on standard ST radials, this is the correct fix, but the construction only buys you margin. It still has to be specified and maintained correctly. Match the load range to the loaded weight of your trailer with headroom above it, inflate to the maximum pressure stamped on the sidewall before every trip and check it cold, and inspect for sidewall cracking at the start of each season. All-steel construction does not make an underinflated or overloaded tire safe.

Best-suited for: Commercial trailers, gooseneck trailers, equipment and dump trailers, and heavy cargo trailers. Popular sizes for the Freedom Hauler Dutymax (All Steel) include ST225/75R15, ST205/75R15, ST235/80R16, ST235/85R16 and ST205/90R15.

Tire Best Features:

• All-steel sidewall and tread construction provides maximum load capacity and resists heavy casing deformation.

• Cooler-running casing built specifically to prevent heat-driven blowouts during long-haul commercial service.

• Stable center rib and closed shoulder design ensure constant road contact, even pressure distribution, and lower rolling resistance.

• Four wide circumferential grooves effectively evacuate water and slush to resist hydroplaning.

• Multi-sipe placement enhances wet traction and dissipates heat to extend tread life.
