Hub-Centric design exactly centers the wheel over the hub providing the best fit possible and the proper clearance for brake rotors, steering components and suspension. Better fit, no wheel vibration! The durable powdercoated finish gives an ultra-hard finish for long life and a great look. The chrome finish uses a dual-stage process to give a deep reflective mirror-like chrome finish that commands attention. Rugged Ridge wheels have been independently tested and certified to meet or exceed SAE J2530 standards for wheel strength and durability.
