Food for thought, I went to a local junkyard and picked up 2 nice sets of alloy rims. One set was ~$60, and the other was ~$100. There were tons of 15" and 16" alloys available, and the weight savings would be something like 5-7lbs per wheel in the same size. Considering how little more a set of junkyard alloys would cost, why not do that instead?

I couldn't guess how much savings moving to a narrower profile would give you, but all else being equal, there would be gains from going thinner.
