1. The LT rated tires are by definition for "Light Trucks" and your MH is way over the weight of a light truck.
2. E Rated tires are 10 ply rated to carry 1140# max per tire. As you can see way under the axel weight of a MH.
I've been doing this RV thing for about 40 years on and off and I discovered years ago that I don't buy any tires under "F" - rating (12 ply) for my MH's or 5th wheel trailers and when available I went to "G" ratings (14 ply).
Knock on wood or my head I can honestly say I have never had a tire blow out on my MH's or trailers. The increased cost per tire far outweighs the body damage usually done by a separated tire or .......
Happy tires.

For those who asked, yes, I weigh my coach at CAT scales, 10,200# rear (800# under) and 5,200# front (800# under) with full fuel, assorted junk in basement, and about 15 gal cargo water, although it has been since last spring that I've crossed the scales.
I check the tire pressure before every departure. Load Range E is the recommended manufacturer tire, and it's on all the stickers.
I suspect at this point that the heat factor is influenced by the engine exhaust that wraps around the wheel well on the starboard side. Any F-53 owners that have had this issue?

Not overly concerned about depreciation with this rig...
I've read your post 3 times and still am not clear if you had a total blow out of the tire or entire tread separation from the carcass ans still had air in your tire?
I know your post says blown tire.

Per Item 1) His GVW is 15,000 lbs and does qualify as a light truck - heavy truck is 80,000 lbs
Per Item 2) An E rated tire 235 - 85 E rated tire is 3042 lbs. Running as a Dually, slightly less, but still waaaay over the 1140 you suggest. 16 inch F rated tires are rare, and not likely to be found in a radial. I am running Firestone Transforce 16 inch LT tires for a lot of miles and a lot of years and have never had a problem. I also tend to run higher speeds than typical. I always run at 80 PSI. They are Nylon belted which is also perfectly fine. An engineer at Bridgestone happens to know one of my relatives. I have talked to him about what I am running, and there is no problem with LT tires or nylon belted.
The tire rating should have easily been within his load. It is unlikely that it is a overloading problem directly, BUT I would suggest a different problem. That position tire failure is more common than any other position. Some have theorized that it is not uncommon for drivers to hug the starboard side of the road to the extent that the outside dually actually is running off the road. This would mean the inside dually is taking the full load of the rear axle and could possibly pose a problem if run that way for an extended period of time.

Did you check for any bruising on the inboard side of the outside remaining tire? You could have picked up a rock in between them, and the could cause the blowout.
That remaining tire was probably way overloaded when the inside tire blew, so I would no longer trust it and would replace it.

I would still recommend that you have it four corners weighed not just each axle. It is possible to be under weight overall and under weight on an axle but still be too heavy on one corner.

We use a Radio Shack temperature gun to check temperatures and a friend had a dually truck with the exhaust system routed near by. The inside dually was running about 30 degrees F hotter that the rest of the tires. I find inside duals run hotter than outside and the sunny side tries run hotter than shady side tires.
The Cooper district manager has refused to honor the tire warranty because, get this, I did not retrieve the tread carcass from the highway and there is no tread to verify the wear was less than 2/32", even though they agree 1)the tire had 4,106 miles on it and 2) there is a twin on the outboard side that was bought at the same time and they can use to measure tread wear.
So if you buy Cooper tires for your MH and the tread totally separates, kiss the warranty good-bye unless you are willing to walk back and into traffic to retrieve the carcass.
