I've been looking at new tires and saw Sonic04Edge's thread on how he actually gained mpg's by increasing his tire size. I have a 3.0 with the 4R44E auto tranny and 4.10 gears in the back on 245/75/R16, so basically the same as Sonic04Edge's. Could I expect to see similar results if I went with the 32x11.5x15 tires as well? I know my current tires are too small because my RPM's at cruising speed are too high. I think a larger tire would get my RPM's down to where they should be, and look cool too.
Any one with ideas?
