http://www.wheelweights.net for weight info. Konig wheels are average quality, but are knockoff styles made with cheaper materials, so they are considerably heavier than others. My old 18x8 Villians weighed 23lbs each, compared to the SSR Integral, which it's copied after, weighing 17lbs. They offer a good line for the budget minded, but most of their wheels are geared towards FWD fitments and don't come in lower offsets to look right on a 240.
