In my case, I was looking at some forged 16" SSR's that were like 11 pounds each and tires for them were 20, so one wheel tire combo was 31 pounds -- about 4 pounds lighter than stock 15's w/ tires. 4lbs x 4 wheels = 16 lbs unsprung weight, so about 160 lbs of overall weight savings. You'd have to tear quite a bit of crap off the car to save 160 lbs normally, so it's a pretty impressive gain.

that is very interesting. I'm sure further studies can be done on this, but I like that thought. Maybe lightweight lugs aren't just bogus lol.. My 16's fortunately are lighter than the oem 15s so I'm happy.
