I. Introduction
KUNLUN Tires stands as an innovative leader in OTR tyre solutions, engineered for the most demanding construction environments. Our portfolio features five specialised radial tread patterns, each meticulously designed for specific equipment—from rock quarries to port logistics and heavy lifting. These radial OTR tires deliver exceptional performance, superior durability, and significant cost-effectiveness, ensuring maximum uptime and lower total operating costs across diverse and challenging job sites.
II. Core Technology & Engineering Advantages
KUNLUN's five-pattern radial OTR tires are engineered for tough construction site challenges. They feature robust radial construction with high-tensile steel belts and reinforced casings, providing excellent puncture resistance and durability, optimized for multiple retreads.
Advanced tread compounds enhance performance by offering exceptional wear life and resistance to cuts in abrasive conditions. The tread designs include features like variable pitch for reduced noise, deep grooves for self-cleaning traction, and stable shoulder blocks for even wear.
Reinforced beads and sidewalls ensure stability against heavy loads and harsh impacts. This combination of technologies guarantees that every KUNLUN OTR tyre is reliable, safe, and productive.
