Guizhou Tire Launches Full‑Scenario OTR Solutions(August 28)
Guizhou Tire Launches Full-Scenario OTR Solutions to Empower Construction Machinery with Cost Reduction and Efficiency Gains
Frequent stops and starts on gravel mine haul roads, round-the-clock continuous operation under hundred-ton loads. In extreme engineering conditions, tires are no longer ordinary consumables but a core element ensuring equipment uptime and controlling operating costs. Leveraging deep technical innovation and smart manufacturing capabilities, Guizhou Tire has focused on the core pain points of construction machinery to build a comprehensive, highly adaptable OTR full-scenario solution, addressing various engineering challenges with heavy-duty durability, EV-specific design, and reliable stability to precisely meet users' real operational needs.
Technology Empowerment: Giant Tires Built for Heavy Loads and Long Service Life
Large-tonnage mining dump trucks operate in complex environments that impose extremely stringent requirements on tire load capacity, impact resistance, and wear resistance. To address these industry challenges, Guizhou Tire partnered with multiple leading domestic universities to form an industry-academia-research team, spending over a decade on technical development to successfully create "Key Technology for Special Engineering Tires for Harsh-Road Heavy-Duty High-Speed Applications." In June 2026, this technology was evaluated by an expert panel led by Academician Zhang Liqun of the Chinese Academy of Engineering and certified as having reached an internationally leading level, establishing a strong technical barrier for heavy-duty operations.
Taking the 53/80R63 giant all-steel engineering radial tire as an example, it can stably carry 300 tons of payload, suited for ultra-large-tonnage heavy-duty scenarios. The product enhances load performance and impact resistance through optimized carcass skeleton structure, balanced stress distribution, and upgraded asymmetrical deep-groove tread patterns. Meanwhile, rubber formulations are precisely tailored to the rock characteristics of different mining areas, effectively reducing tire operating temperature rise and slowing wear, adapting to various complex mine road conditions.
Behind these outstanding performance metrics is the dual empowerment of "Kunuo Smart Drive" technology and Lighthouse smart manufacturing. Powered by the Kunuo low-heat-generation temperature reduction technology, material formulations and carcass structures are iteratively optimized through AI algorithms, combined with nano-silica composites and new high-strength steel cords to effectively reduce tire operating temperatures. The complementary Smart Drive IoT system, equipped with high-precision sensors and a cloud-based big data platform, enables real-time monitoring of tire pressure, temperature, wear, and other core parameters, achieving early fault warnings and real-time condition control. This product series is now widely deployed across major mines worldwide, with service life significantly extended compared to conventional tires, truly achieving "durable and long-lasting" performance under heavy-duty conditions.
Customized Armor: Adapting to the Extreme Conditions of Electric Construction Machinery
Electric construction machinery, with its high-torque output, frequent stop-start cycles, and continuous heavy-load operation, poses entirely new challenges to tire wear resistance, temperature control, and tear resistance. Conventional tires struggle to meet the demands of electric-drive-specific conditions. Addressing this industry pain point, in December 2025, Guizhou Tire leveraged its Lighthouse Factory smart manufacturing platform and Kunuo Smart Drive core technology to globally launch the all-domain electric-drive series — the Dianqing (Electric Stalwart) Series — creating a dedicated tire solution tailored for electric construction machinery.
The Dianqing Series is precisely adapted to the high-torque launch and continuous heavy-load operation characteristics of electric-drive vehicles. Integrating Kunuo low-heat-generation core technology, it employs a reinforced armored carcass structure combined with a high-wear-resistance exclusive tread formulation, effectively resolving issues of tire overheating, accelerated wear, and premature aging under electric-drive conditions, significantly improving operational stability and service life in complex scenarios. The product line comprehensively covers wide-body dump trucks, giant rigid dump trucks, loaders, and other mainstream electric construction equipment, suited for mining, infrastructure, and port operations.
Thanks to its outstanding performance, an electric-drive-specific tire deployed at a mining site in Xinjiang has surpassed 6,000 hours of single-machine operation, with a service life far exceeding comparable industry products.
