well ive had two sets of silver 18s which were both at least 28lbs per wheel as well as the stock 16 inch alloys. all three of those are heavier than my 19inch chrome ones, which are only 25.3lbs each. its not the chrome that adds weight its just the process and materials that make the wheel. the chrome probably adds about a pound at the most to the wheel, if that
just be sure youre up to the task of polishing/cleaning the wheels at least once a day if you get chrome, or else youd be wasting your time and money without taking care of them.
