No real answers here. You were well within the rated pressure of the tires and running at that pressure should not cause a failure as long as you weren't overloaded. The only other piece of information I didn't see was the speed at which you were towing. If you were at or below the 65 mph limit of the tires, the only explanation is the fact that it was another ST belt failure that many of us have experienced.

My Maxxis E rated tires suffered a separation on two tires on the same trip which caused a ballooning of the center tread area where air got between the tire tread and the belts. I had checked pressure cold and we were at 80 psi. Towing speeds were between 55 and 60. My luck was that the belts held together and I discovered this when I got home and in the drive. Here's a picture of one of the distended tires vs. one that wasn't.

That failure led me down the path to my current 16" LTX Michelin's.

All ST Radials , not just the Marathons , are failing and causing extreme damage , and the fact that most of them come from China should not be overlooked .

We were at a rally this last weekend, and I noticed two trailers with budging treads. One set of tires were just over a year old, and were Tow Master brand, and the other set were approximately the same age, and were Maxxis brand. Of course, both were "ST" tires.

Folks, the evidence is overwhelming, in my opinion, that all "ST" tires are junk and only are good for a bon fire.

Not to beat a dead horse, but I also made the switch to Michelins, 15 inch. On a previous SOB trailer, we had tread separation on the Marathon tires that were on it. They were neither too old nor run underinflated. They just separated of their on accord. We were headed to Alaska this spring so I replaced the Marathons on my AS with the Michelins. Took a trial run to Big Bend and then off on a 12,000 mile jaunt to Alaska, similar to the one described in a previous post, including the Cassiar highway, if the north part could be labeled that. No problems with the tires. Not even adding any Canadian air. All the way with Texas air, and you all know that is plentiful. A good upgrade in my opinion.

Any and all ST Radials = Garbage
Any other Radial = Happy Trails

Had a puncture on the Michelin on my TV yesterday. It was down to 17 psi (rear of the truck) and still running. No catastrophic failure except in the wallet. Since it is a 4 wheel drive I now have to decide whether to replace all of them or live with one with deeper tread.
My 2 sets of Michelin LT 15" trailer tires have been to Alaska and Newfoundland and points in between with no failures very seldom adding air.

My 2 cents goes for replacing only the one . The difference in diameter will never be noticed or be enough to ever harm any of the running gear .

Where are all the Michelin tires made? I have them, but I can't recall looking at the sidewall for country of manufacture.

Mine were made in Canada.

The 15" XL ones put on my trailer this summer were made in Canada. The 17" load range E that I put on the truck yesterday was made in the US. I think Michelin has a several manufacturing plants around the world.

TireRack currently lists the country of origin for the 15" LTX M/S2 as either Canada or US.

My '03 Alfa came with 225-16 Uniroyal Larado's LT, I had tread separation on three of the seven. I replaced them with Bridgestone R273 SWP II, advice from Ron's tire in Bullhead City.
I was limited in tire size, 235's won't clear the frame with stock wheels. I was looking at wheel spacers, or new wheels with a different offset for the inside frame clearance and 235's, or the bridgestones. I tried two at first, as I popped more stock tires I went for a full set. I'm still running them six years later.
I use downgrades for a run at the next upgrade, this is where I get the 70 mph max speed, my tv runs best @ 65. Pix in my gallery.

I think you'll find that the body tag recommendation is for Load Range D tires—they have a max of 65 lbs. Load Range E tires have a max of 80 lbs., so for the tire he has he is at the maximum, regardless of the body tag.

We had a blowout yesterday with a less than three year old B F Goodrich Commercial TA E rated tire running 75 lbs pressure and 60 mph. Since it was the road side rear it did all the typical damage. Probably about 2K $ damage. Tire had about 30k miles on it and looked new. Guess they're not as good as Discount Tire said.
