anyone know the benifits of lightweight wheels?

I have 205 50 15 tires on light weight 11lb wheels , the stock steel wheel and tire are still lighter.

This is not necessarily true, because you're not taking the tires into account. Tires can typically weigh between 15 and 20 lbs, and if you maintain the overall diameter of the wheel/tire combo, a lighter weight wheel with a larger diameter would require a tire with a shorter sidewall, thus a lighter tire. Depending on the actual weights and wheel design, the mass can even be moved inward.
