Hi,
I did go to taller tires. If I drive extremely carefully at 48 mph I get 12.5 MPG. If I drive 55 I get about 10.5 mpg. If I drive 65 I get about 7 mpg.
With the OEM size I got about 1 mpg less at each of those speeds.
I've driven the mountains with the taller tires and found no issues with power.
Be aware that new rims are needed if you go to a taller, narrower tire.
Ford is unable to re-calibrate the speedometer as the option to do so is greyed out for Vans. They can do it for trucks.
