Default Ecoboost 3.31 gears 34"tires
Who's running around 33-34" tires with 3.31 gears on their ecoboost?
How is it?

I have 3.31s and 305/55r20 basically 33x12.5 and truck still has plenty of pickup. Didn't notice a drop off in power at all, mpg dropped about 2mpg in city

Thanks for the info! the tires I'm looking at come out to 33.5, 10.6 wide, 55lbs. So should be pretty close to what you're running

Nice, the low (er) weight will help the most. It's the added of weight of the big tires that bogs down the motor the most..

The toyos I was initially going to get are 70lbs, way to heavy, so decided to change the tire style and brand. Getting the bfg at k02's 34x10.50r17
