Losing Weight-tires & rims

[Weirdo_Joe]

First off, does anybody know what each 14" factory wheel weighs? Guy at the tire shop guessed about 27lbs. The tires I have may not be factory... but anybody know the weight for the factory (or average 14" tires)?
I have noticed from taking times in the same place; a 150lb passenger slows my 0-60mph time by roughly 1.5 sec & a 200lb passenger slows the time by approximately 2 seconds. This equates to half a second for every 50 pounds, the way I see it. I am wondering how much weight I can lose at the wheels... probably 50lbs or more. So far, I looked at one that was 17 lbs per rim only to gauge weight... Like, can anybody recommend a cool looking shiny chrome or black/chrome rim that's really LIGHT and a good tire to go with? A guess at the total weight savings (or per tire ; ) would be cool, too! Oh, and wouldn't lighter tires/wheels make it easier for your wheels to spin/be spun? I dunno... seems like something about the rotational inertia, same reason the lighter crankshaft pulley is better. Oh, BTW, looking at 16" rims for the 6 months it doesn't snow here. Thanks! Have a great day.
