3.55 gears with my stock 2017 F150. 3.5 EcoBoost. Stock wheels and tires. Not sure if this helps or not. There’s a chart somewhere that compares tire size and gear ratio. 4.56‘s would keep you in the sweet spot of balanced power and gas mileage.Here's a new question to all the F150 guys - what gears are you running? I'm planning to move down from my stock 3.31's, especially now that I'm pushing 35" tires. Debating between 4.10's and 4.56's. Thoughts?
