Tire swap comes to an end. Swapped back in the Toyo Open Country AT2's this morning, did the math and thought I'd share the results. Take if for what its worth, 100% eco = best effort, DGAS tank = "Dont give a smores" tank

Toyo Open Country AT2's 110k miles on them (speedo was within +/- 0.5 mph)
09/1/52018 425.0 18.432 23.05772569 100% eco

11/10/2018 357.2 17.832 20.03140422 100% eco tune change, went to previous best performer with 33's on there
Totals 2806.6 142.835 19.64924563 <-Average

Coasting significantly improved, even on brand new tires, I expect average will jump back up into the upper 21's, low 22's.

I will update this post after 6 more tanks...

Edit:
