If you happen to go in to a gvmnt scale, ALL they care about is that you are under the road bed limit, which is 20K per axel, with a min wt per inch width of tire of 500 lbs. So a typical private pickup has 10" wide tires, at 500 lbs, is 5000 per tire, or 10K per axel or 20K total for the truck GVW. Ask yourself this, are you ANYWHERE near this limit? thought so!
Reality is, from an LEO standpoint, they do not care what the warranty limit on your rig is. Because it is way under the road bed limit, they will not worry about you, even if over by 150-200%! I've been weighed at 150% of manufacture gvwr, I've yet to get an overweight ticket.
