Need help with load limits
I have a 2014 RAM 2500 CCSB CTD, 5th wheel prep, 18" E-rated tires and exhaust brake. I currently have a popup trailer and want to upgrade to either a TT or 5th wheel. For a TT I know I can hook...

If your loaded pin weight is over 3000 lbs, you'll likely need heavier duty rear tires/wheels and springs.
Why? Other than the fact that he would be over his 10K lbs GVWR because of the class 2B rating, why would he need up upgrade springs or wheels/tires?
Those same exact tires, wheels and springs are rated to have a 3300 lbs payload in the 6.4 Hemi configuration with 17" wheels. We know that upgrading from 17" wheels to 18" wheels gives an additional 500 lbs of RAWR capacity, from 6000 to 6500 lbs. Lets not forget that those 18" wheels/tires are also rated to 7000 lbs on the 3500, so the "weak link" on the 2500 would be the coil springs, rated 500 lbs lower than the leaf system.
OP, check the registration laws in your state. In Maryland I can register my truck for whatever weights I am willing to pay. To be legal, my weights cannot be more than 1) my registered weight and 2)the combined rating of my tires.
I'm fairly certain your 18" tires are rated for 3500 +/- lbs, so if you have 4 wheels your tire rating is 14K lbs. Your combined axle ratings with 18" tires is 12K lbs. If you register your vehicle for 12K lbs, you are both legal AND within your axle ratings.
That is a cheaper way of "upgrading" to a 1 ton truck.
