Where did you get the info that these tires improve MPG by 3%?

One SAE article.... click here...
...another SAE article click here...
.. and another article about the tech they're using....
Goodyear claims 8% when the tire is new at highway speeds using SAE tests, and 4% average over the life, but they don't take into account the fact that as the tire wears, it gradually loses some of its advantage, so I claim its really 3% over the tire life. And, even though its a 65,000 mile warrantied tire, many will trade them in at around 40,000 miles.
Best way to view it is that you get about a 7 cents per gallon of gasoline discount every time you fill up if you have Fuel Max tires. It helps. I gave a presentation at an SAE meeting last May where I went through all the individual engineering improvements possible invented or refined over the past few years, and we noted that, combined, average cars can get about 20% more efficient by doing relatively easy things, and the Fuel Max tire is one of them.
