Found another way to save on gas.

Compaq888, so, since you checked it by measuring everything, what was the diameter change in the tire that you measured before and after overinflating the tires? What did you use to take the measurement? I'm asking because you're citing a 3.1% change in speed and that seems excessive to me for a few more PSI in the tires. Without the numbers, though, it's purely speculation on my part. Please educate me, as I am ignorant of the possibilities here.

As far as the speeding part, I never suggsted anyone should exceed the speed limit. I posed a hypothetical situation and asked a question about whether it's worth it to speed to keep up with the flow of traffic instead of impeding it and potentially causing an accident. I never said it would be more fuel-efficient overall. I was asking a series of questions and so far nobody has offered any answers but SVOBoy is trying to imply that I'm crazy for making a statement that I never made. It probably sounds like I'm leaning in one direction or the other, so shame on me for not wordsmithing my post more effectively.

So there are no answers so far. The question stands: Is less fuel consumed overall if you speed to keep up with traffic instead of driving the speed limit when everyone around you is speeding? Need someone with statistics on that one.
