I ran a test for baseline and did it 3 times to verify.

57 mph on cruise on a 10 mile stretch with a couple decent climbs/descents.

6th gear= 2000 rpm and 49 mpg
5th gear= 2490 rpm and 44.5 mpg
4th gear= 3000 rpm and 39 mpg

Seems to show that less rpm is certainly better. I have room to go up on tire height but 27.5"-28" OD would be maximum. Current tires are 25.5" OD so around a 10% reduction in tire rpm will net how many less rpm's?
