I would be wary of using spacers on a heavily loaded DRW since it will add leverage to the wheel studs.
^This.
And I can’t imagine why it’s even a consideration for an OE size wheel and tire setup.

Weight of the camper should not be an issue on the dually truck. Each E rated tire at 80 lbs cold should handle over 3000 pounds each for 12K. Hence the GVWR of the dually truck. Weighing the truck empty and with the camper loaded for each axel is important. Highly recommend!
On my setup with my lance 10 ft. 95% is on the rear axel and only a measly 5% on the front. I had separation problems for several years (fortunately never blew one always a rear tire) and finally found my air pressure gauge was off reading high by 4 LBS. Replaced that and bought a good one. Since then no problems. I have single rear wheel drive which means my margin is small. Potholes, speed, and ambient air temperature play a big part on tire temperature as well. Always experienced the separation on a hot afternoon or rough pavement (which is the norm in Cali) The shock of hitting potholes can easily cause separation when loaded. I drive at about 60 mph and have been running Hankook Dynapro HTs for the last 7 years.
Just replaced two front after 6.5 years due to cracking on the sidewalls. In a sunny hot environment like Florida and the southwest the sun does take a toll. Garaging should help that though. Rear axel weight empty on my dodge 2500 is only2540 and with my camper is 5840. obviously I run 80 in the rear but only 50 in the front when loaded. Air bags level the Truck with camper and I have auxiliary load leaf springs well just touching the stop. Handles well.
Tires are the weak link for us truck camper people! Use a couple different air guages to verify.

^Respectfully, 4 psi cold didn’t make any discernible difference in tire capacity, causing tread separation.
Any of those hot Cali afternoons you reference, rolling down the highway, your 76psi cold (thought to be 80) tires were well over 80psi at that time n place.
Pressure varies approx 1 psi for every 10degF and at least 1/2psi per 1000’ elevation change.
And the tires’ max rated capacities are generally (always) reached at max rated pressure.
Although to your point, since heat raises pressure, and less pressure = more heat, if you were having heat issues causing the separation being overinflated may have helped. But we’re splitting hairs now.
Objectively though, I have spent a lot of miles in company provided half ton trucks doing things that should be done by 3/4 ton trucks. And most new pickups especially the fleet specials come with the cheapest tires possible, off the assembly line.
When I’m on the OE set of tires on a newer half ton, and saddle it with a load that is over the rated tire limits, tire squishes and gets quite warm/hot after being in use at highway speeds.
Same tire, typically a 45-50psi rated tire, if aired up to a pressure that takes the static deflection out of it, runs notably cooler.
Have put on a fair amount of heavy load miles with 1/2 ton truck rear tires aired up 10-20 psi over max pressure rating, running cool without issue.
Not recommending it per se or at all, to others, but it’s evidence that more pressure reduces heat.
A little beyond the original discussion I know, but good info imo for those who may not realize it.

Guess l was hoping to get a consensus on the best available tires to use on a dulley carrying a 5000 lb TC. I'll probably look into the Toyo brand for my next set. I believe heat could be causing most of my separation issues as in summer months as read on my TST monitor I can see Temps reaching 110 degrees with pressure rising at least 10 to 12 percent. A few months back I opened the trunk of a car I own to find a BFG TA exploded Tire was 6 years old with very few miles used as spare,also vehicle is always garaged. I tried to post a photo, but couldn't. I'd be happy to email or text the photo to anyone to post. Just private message me..... So its my opinion most if not all tires are not made well these days. Just read trailer or class A form...

My last 3 sets of tires have been Sailun terramax AT's I moved from BGF all terrain ta's to them and couldn't be happier. I get about 10000more miles of tread life out of the sailunes, better traction in the winter, they handle the water on the roads better and run a little quieter on the highway. oh, and there less than half the price.

Wow! Honestly you may just be on a slow roll of bad tire luck! (No pun intended, lol). Seriously. Doesn’t sound like you’re doing anything wrong.
Although do take a moment to figure out what % of rated capacity you’re running, especially the steer tires on the dually.
Im not very tire paranoid in general, but you don’t say what tire size you have on the truck. And you could be right on the cusp if you’re running 16s and have 215s on it.
I’ve beat enough tires to death to form my opinion that I don’t believe there is a marked difference in quality between any of the popular brands. I’d feel the same about running Toyo, Nitto, Cooper, Goodyear, General, etc. But adjectivally, Toyo is top of the heap imo.
For pics google Rvnet Photo Posting. Then you can select a pic a couple ways and then copy the link and paste it into your post. It’s clunky but easy.

Thanks, I'm keeping a list of recommendation, and will add Sailum if they offer a road tire.

10-4 Mr. Gritdog,
Maybe the OP has had some bad luck as I did for several years and is frustrating.
Fortunately my tire failures were detected by vibration from the bulge in the tires or by inspection at a stop and pulled off before they blew. Always on a rear tire either side. Had a series of this problem ( maybe 4 times over 5 years) only during the summer hot months with camper on) with Goodyear Wrangler and Remington tires not bought at the same time. I believe Remington was also made by Goodyear at the time. Running Hankook the last 6 years with no problems and now on my second set using the new tire pressure gauge over that time frame.
Don't trust the cheep gauges and cross check between gauges. Insist on steel valve stems. Check the TP first thing in the morning before the sun hits them. Inspect at stops. Avoid potholes! Good luck with that.
80 lbs per tire gives about 280 lb extra carrying capacity on the rear axel vs 75 lbs per Goodyear chart on my stock 245/75/16 E rated tires. 6084 vs 5800. These tires were widely used on class C motorhomes as well in a dully configuration.
Next truck will be a dually and of course a heavier camper!

^Yeah those little tires get overloaded pretty quick.
Stepping up in tire size is generally always preferable for heavy loads. As long as they fit and you can pull em.

The truck is a 2003 3500 ext cab two wheel drive diesel dually. Running stock size tires 215/85R16. I only had one front tire seperate,that was a BFG.rest have been on the rear. I thought about going to a large tire,but was afraid it would make the rear space even closer. Since three of the four rear are new replacement Goodyear and the other has 15k I'm just staying with them for now. As far as posting photos may be easy for some. Just like rebuild a Pontiac engine is easy for me...
