In the first few photos of the tires, the ones with the Vietnam code, does it say those are 6 ply tires? The number is actually "276" ply. I'm not sure what it really means. That doesn't seem right. G rated Sailuns are 14 ply, my tires clearly say that on the sidewalls and don't have the DOT codes like the ones in the photos, just the date code.
This is an important question here!!!
6 PLY tires? What does the 276 ply indicate?

Following this thread with interest.
I bought my Saliuns from SimpleTire on 9/11 (2020) and had them mounted at a local Discount Tire a few weeks later. I will bet I have not put 100 miles on them yet. Our first trip since COVID will be in September.

My tires are "Made in China" with a date code of "2220" which is mid-May 2020.
My DOT marks say "MW 27" - I have no idea what that means.
Other marks: Plies: Tread Steel-4 Sidewall Steel-1...if my math is correct 4+1 = 5 plies...??? What are they supposed to be??

Edit: I found the notation "14PR"...not sure what that means.
also found load range 4080 lbs at 110 psi
and I already have metal stems.

Keep looking, they will say 14PR somewhere on the sidewall. Also look for the load range. (LR)

I'd invest a couple of bucks for metal valve stem caps.

Here is what the MW is with the new plant code identification.

MW = 1MW

I had a tire failure on my 2020 Montana. It failed because the valve stem was loose so it went flat but did not disintegrate. While running on low pressure it did visible damage to the tire but it did not completely disintegrate like yours. I called Keystone customer service and they gave me a phone number for Sailun tires – I called them and they shipped a new tire to my front door. Keystone Montana then paid (reimbursed me) for the labor to mount the tire onto the rim.

I just looked at the new Sailun tire I put on two weeks ago. It's a 1YJ, made in Vietnam date code 4920. I will be watching it closely.

I'm only guessing, but the 276PLY in the photo above appears to be part of the plant code, not that it is 276 ply tires.

Same here. Had them mounted last Friday. FedEx lost one of the four, so Simple Tire is shipping me another one. So far I have about 300 miles on them but time will tell.

Here is a reference that explains the DOT identification number. There are reasons why the entire number may not be on the sidewall you're looking at.

Correct low pressure warning. But the tire was still holding air.

For me the tire was running 15⁰ hotter than the others. When I pulled over I used a laser thermometer to check the tires 120⁰F (same as TPMS), the hub, 167⁰F and the drum 248⁰F.
I suspected the brake was dragging. When I went underneath I saw the brake spring wire sticking out of the inspection hole and it rubbed a groove in the tire. I bent the wire out of the way and went slow down the road 20 miles to our next Campground.
There I replaced the tire and brake assembly.

That is not a manufacture defect. Tires wearing in specific areas have something causing extreme heat to that spot. Loss of camber and or overloading. Hard to tell for sure, but it also looks like maybe something is gouging or rubbing where you see the belts.

Is that tire the same size as the OE tires?

This is a tire in the first stage of disintegration. The tread wear looks acceptable so no extreme alignment issues. It would require proper analysis to determine why separation is happening but manufacturing defect is still a possibility.

Replacing tires

This post was timely for me. Getting ready for a trip to Montana from FL and need new tires. I have Goodyear Endurance and no issues other than not getting many miles out of the set. Realize they have only 11/32 tread new. About 8000 miles and they have less than 4/32 remaining. That’s option 1 to replace with the same

Option 2 had been Sailuns due to many posts about reliability but this is 2nd recent post about Sailun failure so losing confidence. Don’t need a Vietnamese bomb. Also they are rated for 110 psi while my wheels are rated for 80. One common thread has been tire failure due to under inflation. A Valid concern to have 110 tires and only inflate to 80? I currently run 75psi on the ST235/80R16 and only drive 60 so have had no issue. I take longer to reach my destination but good mileage and peace of mind. And the tires are only rated for 60mph.

Option 3 for me are LTs and concern there is clearance between tires and also top of tire to floor. Right now I have 5” between tires and 3 1/2” from tire top to floor
Is that valid and any other concerns I should have? The distance between axles is 35”.

Our rig is is a 2015 High Country HM318RE.

Appreciate anyone’s insight. Thanks. Ken

Once fixed I will be selling my unit and ordering SOB, with that said the wife does not want these tires on our unit. We have decided to go to boar tire and wheel combo using 19.5 commercial tires. On our 2018 this is the 3rd set of tires and would have been equal in cost with the commercial set up. 600 ish per set, wheel and tire. Just a thought.

I cant see any reason for replacing your OE tires with another size. I'm guessing your trailer has 5200# axles. The minimum tire requirement for those axles is, yup! 5200#. Your current tires are providing 6840#, when properly inflated to 80 PSI. Does your certification label recommend 75 PSI?

You're not going to find ST tires with a mileage rating. They are age out tires. You're already running the only USA made trailer tires.
