Seems like you already have higher rated tires than the rear GAWR with about 1000 lbs excess capacity already, why change tires or wheels? Try the setup as is, then decide if you need air bags, etc. to level the load.

You have one miss stated number.

gvwr=16000#/load=14860 should be GCVWR.

What is the GVWR, total weight on TV wheels?

I hope you understand this reply. The RV industry is set up on absolute balanced measures. The actual measures could be far from the calculated balanced measure, I've not settled on measure to de-rate the trailer GVW, but I'm thinking that axle weight without the tongue weight subtracted is a good place to start. Most trailers are severely out of balance both left to right and front to back. To get a scale weight and distribute it between two axles is not represented of what is actually happening. I try to have one tire capacity equal to 75% of the calculated two axle load. This will give you capacity to cover most of the un-equal load conditions.

OP is talking about the truck rear axle load, not the load on trailer axles.

You don't need to pump E rated tires up to 80 psi with a 1/2 ton. When I had E rated Mich on my 2010 F150, Discount Tire said 45 psi was all that's needed to achieve the load ratings for the truck. I ran 50 psi when towing. Never had a problem with the rims in 2.5 years. I ran 35 psi empty. Psi ratings are corresponding with load ratings. My 12 Ram says 45 psi rear cause it's only 2800lbs empty. It says 65 psi front cause it's 4800lbs (CTD) empty. Heavy loads they recommend 75F-80R. Your 1/2 ton will never see those heavy loads so running less psi is all that's needed.

Rawr 4200 #/load 4360 , gvwr=16000#/load=14860, max trailer#=9700/load=9000, rear tire rating=5340/load=4360#. Truck is a 2009 1500 maxtow 6L. If I go to e rated tires will I need higher rated rims , stock 17 in. rims. It has a.9.5in ring gear 14 bolt diff.g80 locker.

GM small semi float rear axles don't like to operate over its RAWR. RAWR can be from 3800-4000 lbs depending on model. However not knowing which vehicle he is asking about I'm also guessing.

If a 1500 with semi floater, I agree 100%,exceeding GRAWR is not a good plan.

I respect my rear axle rating, I state that being over om GVWR by a bit. I am currently well within the rear axle rating.

So being a 2001, I think the weight taging didn't really start until about 2006. The truck cam with the factory Camper Package, larger rear springs and larger higher load rating tires.

It would be helpful to know what the TV was.
