Not sure if that's useful.
Thanks everyone. Makes sense 275 would fit in spare carrier, it's not much different.
I'm confused about putting the spare on the front is ok in 2wd... what if the flat is on the rear? I have lsd. Are you saying I'd have to take the front tire off, put on the back, then put the spare on the front? That would be problematic with one jack. I kind of have to think that for short distances the 235/70 is ok, I can't believe Ford would make things that complicated?
When I get 31" I could take the best of the 235/75's and put on the spare.... but it's still different size than 31".
Per my post on the sticker I'm planning to go to 31" since Ford says that's how the truck was built (and it should make the speedo more accurate), that makes even more of a difference to the spare. I can try and see if 31" will fit in carrier (means buying 5 tires). Alternatives are several as to mounting it otherwise, thanks for all the options for that.
What I said about 235/70 as max size in the carrier is in the shop manual. But we know there can be errors there. I mean, either it fits the carrier, or not, regardless of what the book says.
I shouldn't have to worry about offsets since putting 31" on is just making it like it was as-built, there should be zero problems about that.
