actually dave, quite a few have.
As a general note, frank lee commented that trucks doent see a benift.
But the trick to the equation is how much highway miles you are driving vs city driving.
Also you cant be going from 15 rims to 17 rims, because then the issue is the extra wieght. But a 4-7% increase in diameter (given hwy driving) absolutely will result in betterr mpg.
Just common sense alone would have to question your 1 in 10 statement.
