This is where you involve a good tire shop that will take the time to trial fit tires and wheels.

I suggest you do a little research before making any purchase. Tire/wheel diameter should be as close to factory specs as possible. You can use a combo of wheel diameter to tire height to accomplish the look you want but anything tall will affect the handling characteristics of the truck, which has a high center of gravity to begin with. If you go with low height sidewall tires you'll probably destroy the rim if you lose a tire at highway speed.

You usually can go one or two sizes up on a truck without any problems.

You usually can go one or two sizes up on a truck without any problems. I went to 285/70-17's from 265/70-17's on my F150 and the handling and off road traction improved with an extra 20mm of rubber on the road.

My concern was with the height of the tire, not so much the width of the tread. But still, you're within to the outer limits Ford recommends.
