Update: Rolling resistance has dropped to a point where I can now coast down most if not all of those flatter hills. MPG still in the 20~21 mpg range, going to go after the tune this weekend and attempt to get it dialed in for the added load. Where I believe the issue is, is in the uphill climbs, the added 5# of rotational mass & the slight gear change with the 1" taller tire has big enough effect on throttle response to cause the drop in mpg.

These tires are still coming off in the coming weeks...
