Milage on my trip today. 2.0 liter ecoboost.

[Baloo]

My ford dash meter is within a tenth or 2 on all my fords (6) since 2016. Ford however undersizes the tires by having the manufacturer skew the numbers and typically are up to 1/2” smaller diameter( gives them better epa numbers to maintain the cafe rating) Two fixes,
1. Forscan to adjust the Speedo spot on
2. I like the look and buy bigger tires. On the maverick I bought 235s (1/2”) larger diameter made my speedometer spot on and also the estimated mpg.
I use forscan when I run 35” rubber on the 150s.

I went to 245's.. my speedo is dead on according to GPS.
