I have a 2012 company 6.2 with the 4.30s and a 3" rough country suspension. I have run both 35s and 37s on it. 15mpg Canadian gallons with the 35s. Just a hair less with the 37s. The truck feels better to me with the 35s. This truck has tuner, intake and exhaust as well. As a side note, the speedo read fast with the stock 275 tires on it. It reads dead on with the 35s. I was able to make a correction with the tuner to dial in the 37s for a correct speedo reading. I have a 2017 on order with the same specs. I will do the exact same mods to it.

I have a 2017 F250 Platinum with 4.30 gears and running 37x13.50x22 Toyo Open Country MT's on 22x10.5 -32 offset. I have a 6" 4link Fabtech suspension. Seems to be running just fine although I need to adjust my speedometer as its off by 5mph. I floored it coming out of a toll booth tonight and the shifting was a little confused, but normal driving it shifts fine. I think I am going to put a 5 Star Tune on it. It looks beast with the 6" lift and 37's more than any 35's I have seen on the new Super Duties. MPG around 11.5 which is a slight reduction from my previous 12.5. Happy to answer any other questions.
