Zhigu's 15-inch alloy wheels are engineered for compact cars, city vehicles, and classic models. Constructed from either A356 cast aluminum or 6061-T6 forged aluminum, these wheels feature PCDs compatible with popular 4/5-lug patterns (such as 4x100, 4x114.3, 5x100), center bores ranging from 56.1-67.1mm, and offsets between +30 to +50mm. Forged variants offer a 30% weight reduction (e.g., 7.2kg for a 15x6J rim) compared to cast models (10.5kg), significantly enhancing fuel efficiency and handling dynamics. Design options include 5-spoke, mesh, and Y-spoke patterns, with finishes such as matte black, silver, and custom colors.
