With the competition to post the highest capabilities possible for every vehicle used for towing and hauling out there, my feeling is they may "slightly" overstate rather than understate their weight numbers.
By incorporating an "expected useful life till failure" in their numbers they can increase stated capability without increasing metal.
I have no "basis in fact", to feel this way; but it is used in aviation designed limits (speed limits, G Loading, max and min takeoff/landing weights, takeoff and landing cycles, etc). Only by saying "What do I expect it "to do" before it fails and yet last 10 years," can you find limits.
If an aircraft's "useful life" needs to be extended, the design engineers go through every longeron and strut with an NDI (non-destructive Inspection) team X-Raying and Magnefluxing everything to determine what need replacing. This is called a SLEP. Service Life Extension Program. Anything close to failure needs to be replaced and even THEN they get it wrong and there is a wing or fuselage failure without warning. (You may remember the C-130 fire fighting aircraft some years ago). I see no reason that truck/car engineers would be trained differently.

If you exceed the maximum stated capability you will shorten the useful life of your vehicle. Depending on the degree you exceed it; the length of time it is exceeded (or both); it can seriously degrade it's useful life.
