The Halmahera Bus Radial 11 - R22.5 - 16PR Truck Tire - Rough Tread - GT Radial - GT668 is a premium commercial radial tire with an 11-inch tread width and a 22.5-inch rim diameter. This tire is specifically designed for heavy-duty vehicles such as trailer trucks, trailers, and intercity buses operating on highly rugged terrain, including bumpy asphalt roads, construction sites, plantations, and mining operations. The radial (R) construction provides superior sidewall flexibility, absorbs vibrations and impacts from uneven surfaces, and reduces internal heat buildup during long-distance travel. The 16PR (16 Ply Rating) specification indicates the strength of the internal tread structure, provides maximum load capacity, and provides high inflation pressure. This makes this tire ideal for drive axles under full load conditions and intensive daily operations. The Rough Tread pattern refers to a tread design with aggressive blocks, wide deep grooves, and pronounced tread grooves. This pattern provides optimal grip on soil, gravel, crushed stone, and mud, while also independently clearing loose material as the tire rotates. This tread characteristic significantly reduces the risk of slippage when the vehicle is traversing steep inclines, slippery descents, or unpaved project areas. The GT Radial brand guarantees global manufacturing standards with modern rubber compound technology that resists minor cuts, cuts, and uneven wear. The GT668 model is the flagship variant for heavy-traction applications, with a specially designed tread depth to extend mileage per wear cycle. The rubber compound in the tread area is formulated to withstand excessive heat from prolonged friction, thus maintaining a stable tread shape. This tire uses no recycled materials in its internal structure. Each unit is manufactured in its original factory condition without any construction deviations and undergoes a series of quality tests, including dynamic balance tests, radial load tests, and heat resistance tests to ensure optimal safety and performance. The sidewall is designed to withstand curb impacts, ozone effects, and direct sunlight exposure. This tire can operate at high inflation pressures without excessive deformation, making it suitable for long routes with extreme temperature variations. With its emphasis on rugged grip, maneuverability when carrying a full load, and efficient operating costs per kilometer, the GT Radial GT668 is the top choice for fleet owners who prioritize productivity and active safety in difficult terrain.
