What you are missing here is that the factory spec for the tires has nothing to do with the truck manufacturers guidelines on minimal production costs and standards or what truck they are mounted on. It is a tire manufacturer's specification not a Ford, Chevy, or Dodge truck specification. Granted it probably is conservative in order to make sure they won't get sued if a tire comes off a smaller wheel, no matter what anyone has done and gotten away with. I'm fully aware that plenty of people violate the tire manufacturer's specification and have gotten away with it without incident. However, no matter what the suspension has been modified to it has no bearing on the tire manufacturer. They do no differentiate between vehicle or suspension type, they only care about wheel size and width, that is where they tested them and made 99.99% sure there will be no problems and where their lawyers feel comfortable.Regarding factory specs: These specs are of the engineering design to be conforming to the manufacturers guideline for minimal production costs and to meet minium set standards, and do not represent the total structural abilities of the truck, especially with other modifications having already been done. ( Linda has a 2" lift...now the suspension and steering geometry is different from factory spec.) My thought was that the factory specs are now no longer the "law" regarding tire fitment.
