On November 21, Haian Group reached a pivotal milestone—the America Subsidiary under its Overseas Business Division successfully shipped the first batch of 59/80R63 giant OTR radial tires to the North American market. This move not only marks our company’s attainment of a world-leading level in the field of ultra-large OTR radial tires but also successfully opens the door to the North American high-end market—a region with extremely stringent quality requirements—earning international acclaim for "China Intelligent Manufacturing".
Haian Group has achieved regular exports of tires of various specifications to high-end markets such as North America and South America, but the debut of the world's largest all-steel giant tire 59/80R63 marks a breakthrough in new technologies within the field of ultra-large OTR tires. Notably, our cooperative client this time is one of the world's largest mining groups; its stringent quality standards and large-scale application scenarios not only validate Haian Group's hardcore technology but also signify that our strategic foothold in the high-end mining equipment market has reached a new height.
Entering this high-end market highlights the leap in Haian’s overseas business layout from "quantity" to "quality", enhancing the brand image of Haian Group in the global market for heavy-duty mining equipment.
Mastering Core Technologies: Forging the Hardcore Strength of the "Giant"The 59/80R63 giant OTR radial tire is a "super equipment" for mining trucks over 360 tons. Integrating multiple cutting-edge technologies of Haian Group, its exceptional performance serves as the linchpin for entering the high-end market.
The core advantages of this star product stem from five technological breakthroughs:
Extreme Specification: With an astonishing 63-inch rim diameter, it ranks among the world’s largest mass-produced tires, boasting a single-tire load capacity exceeding 100 tons—representing the top industrial level in giant OTR tire manufacturing.
Superior Durability: A special tread rubber compound, combined with a deepened and widened giant tread groove design, endows the tire with excellent tear and cut resistance. It effortlessly withstands the dual challenges of sharp rocks and extreme cold in mining areas.
Excellent Heat Dissipation: Advanced radial structure design and high-performance steel cord materials effectively reduce heat generation during high-speed operation under heavy loads, significantly delaying thermal aging. This greatly extends the tire’s service life and uptime.
Stable Traction: An optimized ground contact shape and pressure distribution design ensure exceptional traction and stability on soft or rugged roads, improving the overall operational safety of heavy-duty mining vehicles.
Steel-Boned Structure: A reinforced "third-generation" carcass structure, using multi-layer high-strength frame materials, builds a robust "skeletal system" for the tire. It resists massive impacts and punctures, minimizing the risk of abnormal damage.
Serving Global Mining: Empowering Top Mines for Efficient OperationsThis 63-inch giant tire is mainly fitted on the world’s top-tier ultra-large mining dump trucks—these "mining giants" are the core hauling capacity of modern efficient mining areas. Its exceptional performance perfectly meets the stringent application scenarios of large open-pit mines (e.g., iron, copper, coal mines) that demand extreme uptime and reliability from equipment.
The shipment of Haian Group’s first batch of 59/80R63 giant OTR radial tires is far more than a commercial delivery. It is a powerful declaration: Haian now possesses the hardcore strength to compete with international giants on the global high-end tire manufacturing stage. As this benchmark product sees successful application in the North American market, the excellent quality of Haian’s "intelligent" manufacturing will receive the strongest validation—opening a new chapter for the group’s global high-end strategy in the future.
