The tirerack.com, where I usually get my tires (or from a local Discount Tire store, who will match tirerack.com's price) has Freestyle 225/65-17 Fuel Max tires for $103. Four will cost $412. After that, over the life of the tire, if you get a conservative 3% better MPG fuel economy, thats equivalent to about 7.5 cents per gallon of gas purchased discount. You save about $142 dollars on a Freestyle ( average 21 MPG, assume tires go 40,000 miles). Therefore, the true cost of Fuel Max tires is about $100 less than $412, or $312. Its $100 because of the interest rate penalty for spreading the savings out over 3 or 4 years of the tire's life.
Also, thats money that never made it into the hands of Hugo Chavez or the Saudis. Thats the best part.
A fleet manager friend of mine told me Goodyear is putting this Fuel Max rubber materials tech into truck tires, too, and the website at Goodyear Fuel Max FAQ for truck tires using Fuel Max, which also applies to car tires... click here

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.
