I am back for an update:
First I want to thank everyone for the advice!!!!
I weighed the rig this weekend (those CAT scales are pretty cool), I do not have the exact numbers in front of me, but truck was about 10,600 total, just over 6000 or rear and remainder on front. OK, there @ 11400 GVW, 7000 rear GAW, 6000 front GAW. Truck is right about 8000 empty so 2600, or so, pin weight.
And MORE IMPORTANTLY about 10400 on trailer axles, lighter than I thought.
So I am waiting for my new wheels from Etrailer DexStar 16x6 Steel wheel rated at 3960 @110 PSI. Went with the heavier ones for a few bucks more.

My local tire dealer is bringing in four Bridgestone Duravis R250s for $195 EA mounted, appears to be a good price.
Hopefully will get wheels early in week, then get tires then get them installed in time to head for the Fryeburg Fair!!!! WooHooo
Thanks again everyone!
