Well, if you still have your aspecs...my current 19's were about 2.5 pounds more each. and that was with 235 rubber. Not light, but not bad.

You may have just convinced me. If it makes the car drive more effortlessly and possibly more fuel effecient (from what I've read) and with the AC having less of a toll on power, I'm in. Especially since I have the torque gun to handle breaking that bish loose!
