I also looked up a 185/60/14" tire which is only a .09% to fast which is pretty good but that would mean I would have to find a 1" larger wheel set which might add more weight and no Resistance saving tires in those sizes.
Also they do not sell any ECO - Energy Saving or Low Resistance tire in those sizes.

They do make two decent Low/Eco Rolling Resistance tires in my current 175/70/13 size which is the:
eco Solus HM KR22
Section Width: 7.1"in
Overall Diameter: 22.6"in
Tread Width: 5.8"in
Weight: 16lbs
Revs per Mile: 919
$228 per set


And the Michelin Harmony
Section Width: 7"in
Overall Diameter: 22.5"in
Tread Width: NA
Weight: 16lbs
Revs per Mile: 923
Cost $308 per set

People do seem to be getting around 30-50k miles out of the Michelin compared to the Kumho tires in this size.

I don't know if this tire would get any better MPG then the smaller stock size& I would not like the difference in my spedo either.

Would possibly getting a taller tire then stock raise my MPG? I have not looked into it.
