Tire Help !!!!

Has anyone run Military spec 37x12.5 R 16.5 tires on the F250-F350 I am currently running 31x10.5 R 16.5 My question is this, is it worth it switch and do you need to mod the truck when you do ? ( wheel spacer, lift kit )

I am assuming you're referring to 4x4, if so, the stock F250 can clear 37's if the springs are fresh (original ride height), but if they're worn (sagging) you're going to rub.

No, actually I own the f350 one ton 2 wheel drive, but I love it and that's why I was asking.

305’s are about the biggest that will fit my 2wd. They are equivalent to your 31’s I believe. They rubbed at full turn on my ‘79 F250 so the 37’s would be worse. I’d say no.

Edit:
315/70’s were quite a bit bigger and would not fit my 2wd, the tires you are looking at are equivalent to 318/82’s.
