I have been reading all the posts on this subject and decided I could add one more. I am a firm believer in weighing my vehicle before each big trip south to ensure I am not overloaded. The one thing I notice each time is that the weight is not transferred to the front wheels. I weigh hitched up and unhitched so that I can see my pin weight. The weight on the front wheels does not change by any more than 10 lbs on both weighs. I carry 65 in front and 80 in rear. I was carrying 55 in front but an inspection of my tires resulted in me increasing the pressure to 65. I think, my opinion, that 80 in the front is going to cause tire wear.
If you can't play a sport....Be one.
