Targeting mid-size cars, crossovers, and performance sedans, Zhigu's 17-inch alloy wheels blend 6061-T6 forged aluminum technology with functional design. Forged models (8.5kg for a 17x7J rim) reduce unsprung mass by 25%, improving braking responsiveness and cornering precision, while cast options (11kg for a 17x7J rim) balance cost and durability for daily use. Sizes range from 17x7J to 17x9J, supporting tire widths of 215-255mm with offsets from -10 to +45mm and PCDs spanning 4x108 to 5x120. Customization options include deep concave profiles, diamond-cut finishes, and 2-piece modular designs for aftermarket enthusiasts, all certified via JWL/VIA impact testing and 500-hour salt spray testing for corrosion resistance.
