About Diamondback Tires

Diamondback is a tire brand with serious manufacturing credentials behind it. Diamondback tires are manufactured by Triangle Tire USA, the North American arm of Triangle Tyre — a global tire manufacturer founded in 1976 and headquartered in Weihai, China. Over the decades, Triangle Tyre has grown into one of the largest tire manufacturers in the world, operating multiple state-of-the-art production facilities and maintaining a presence in markets across the globe.

In North America, the Diamondback name is synonymous with dependable specialty and commercial tire solutions. The brand has earned a reputation for building radials that meet stringent quality benchmarks, including passing FMVSS 139 standards — a key requirement for original equipment trailer manufacturers. This level of certification signals that Diamondback tires aren't just shelf products; they are engineered to satisfy the demands of major OEM supply chains.

Purpose-Built for Demanding Applications

Diamondback's lineup is purpose-driven. The brand is particularly well regarded in the specialty trailer tire segment, where durability, load capacity, and consistent performance across varied road conditions are non-negotiable. Specialty trailer (ST) tires face unique stresses — constant load bearing, highway speeds, and extended use without the self-cooling benefit of a driven axle — and Diamondback tires are built with these realities in mind.

All-season rubber compounds are a hallmark of the lineup, delivering reliable traction and tread life through changing weather and road conditions. Whether the application is a utility trailer, boat trailer, or heavy equipment hauler, Diamondback's commitment to long service life makes these tires a practical, value-conscious choice for fleet operators and individual owners alike.

Backed by a Global Manufacturing Leader

What sets Diamondback apart from many value-tier tire brands is the infrastructure behind it. Triangle Tire USA brings the resources of a world-class manufacturer — including dedicated research and development capabilities — to every tire that wears the Diamondback name. Triangle Tire is also recognized for its environmentally conscious manufacturing practices, a factor that has resonated with major distribution partners. The result is a tire brand that offers competitive performance and build quality without compromise.

For drivers and fleet operators who need a reliable, road-tested radial that delivers on its promises, Diamondback represents a smart choice in the specialty and commercial tire market.
