I have had some tires that made a truck pull from one side to another on rough patchy roads, but most times there's a issue with the steering.

How much free travel is in the steering wheel, it should have less than a quarter turn, 1/8 turn is better but it does need some free travel. Check the free travel in the shaft next to the steering box as there's a couple of ujoints in the steering shaft between the steering box and steering wheel that can give a false reading.

If the steering wheel has to much free travel check these.

tie rod ends

drag link

Steering box adjustment

I've worked on, owned and driven several Ford L series trucks and have replaced more worn drag links than any other part on the steering.
ujoints in steering shaft

slop in telescoping shaft

If steering is tight check these

king pins, jack up the front axle then pry up on the tire to check for movement

alignment, should be toed in 1/8 inch

wheel bearing tightness

spring eye bushings and pins

spring shackles and pins
