I can tell you how it works for me. I put on four new, matched tires and leave any old thing for the spare--which is almost never used.
It's infuriating to me that the tire makers don't guarantee the rolling resistance of the tires. And, my response is that I hold them accountable if the tires don't measure up. I'm quite serious about returning tires if they don't give satisfaction. If you are up to measuring the rolling resistance coefficient of your tires, then that's what I would do. Otherwise, carefully track your mileage before and after you get them.
Some of us have mileage computers in our cars, like the ScanGuage. That makes comparing performance of tires much easier. If the new tires are a different diameter than the old ones, be sure to correct for that.
