Even though it's rated to 75, I try to keep it at 65 or under.
Looks like your tires are the "newer ones"... Do you happen to know the date code on your tires? And.. are they all the same date of manufacture?

They show 0315 as the date code. I believe they are all the same.

My factory tires on my 2016 Montana have the L on them also but if you see my 5er going down the road at 75 MPH please call the police because it has been stolen.

My Maxxis ST tires are made in Thailand.

Good though about adding another 2000 to my already 10000 miles I put on my trailer kings 16s. I bought saline G tires today there rated at 4050 lbs reminding me of a semi trailer tire. My stock trailer kings seemed to make air they where always over 80 lbs. I let air out again to 80 lbs. Its at the dealer for service work now. My experience is pull under 65 and have the max air pressure.

The age of the tire alone would be reason to replace them soon. Sounds like you have taken good care of them.

Here is a PDF of the Michelin warranty package. Read “what is not covered” starting on page #2.

Here is another Michelin reference. Under tire replacements click on "Do I have to replace my tires with the same size?

I wonder how "poor construction" was established? A tire forensic expert can do that with a tire in hand. Maybe it should be sent to NHTSA for further investigation.
Bought 7 LT Xp ribs from American tires they mounted and balance the tires. And bought the warrenty. So I guess I have a warrenty as if it was on my truck I had towmax.

Kumho makes an amazing D rated ST tire, the 857, in Korea. Even our lowly 205/75R14 is rated to 99mph (nice to have lots of headroom) with that extra load capacity for larger units who come equipped with 14 inchers.

Esmoglo, do you hear that loud snickering in the background? We have ALL heard of Trailer King tires. When reading the horror stories of blowouts the most common brand would be Trailer King or their associated brands. And keep in mind that 5 pounds under proper pressure coupled with 5 miles over max MPH, AND a Trailer King tire is a recipe for road side assistance and a call to Geico.

The above is an accurate statement. The word SHOULD is the critical point. I kept (keep) my tires at the recommended psi religiously. I don't drive over 65mph. The tires are covered when parked for long periods and are in a enclosed storage facility when not in use. I do a walk around at every gas stop checking the tires and wheels. All of this including having all tires pulled and inspected by a local tire dealer before departing Monday (they said the tires were in "excellent" condition). 50 miles out the tread completely separated from the tire as if it was never attached to the carcass.

All that to just say if you think that because you keep your tires aired up and check them, it absolutely means nothing when it's time for the tire to "go" for whatever reason. I'm afraid you will be in for a big surprise.

Although it appears there is no rhyme or reason to the failures and some folks have good luck and some don't I think there may be some common denominators. 1) Tires that are put on the trailer that just barely cover the weight of the trailer (mine is one) resulting in overweight conditions when traveling over a highway like I20 in Shreveport, which I've done multiple times, 2) poor/inferior construction materials or methods used in China. I know there are specs that all tires have to meet for sale in the U.S. but the evidence is irrefutable that the Chinese tires fail dismally. I have had two independent, knowledgeable people look at the tire that came off my trailer and both agreed that the tire just wasn't constructed as it should have been, 3) folks fail to adhere to the requirement of maintaining pressure and speed while not looking at their tires frequently and 4) those that tend to want to stretch the life of the tire beyond its intended lifespan.

I think if you did all of the things a person could do to minimize a tire "event" you would still be susceptible to the "no rhyme or reason". IMO if you bought 5 Trailer King tires today you would have a 50/50 chance of a tire destructing by 2 years. That's just my opinion - I know how I take care of stuff and know our issue was definitely not manmade.

The unfortunate thing is nearly all trailer tires are made in China. Carlisle has a new one out that says it's made in the USA and Maxxis is made in Thailand. The Maxxis reviews are stellar compared to all of the rest. I am having 5 new Carlisle's put on our trailer as I write because I couldn't wait for the Maxxis tires to be shipped in. I hope/anticipate they will last this year, and next year, when we aren't under pressure to get to FL, I will have a set of Maxxis ordered and put on. It seems a waste but I am now phobic about the tires on the trailer and can't stand to constantly be on pins and needles every second while I'm driving; I want to enjoy the trip and not be worried all the time. Just my 2 cents.

I dunno if that's the complete equation for success. I think there's at least a third part. Tire brand. I think buying the right tire (Maxxis or Carlisle or Sailun), proper inflation, remaining below the tire's speed rating and, of course, balancing said tire is about all anyone can do to shift the odds in one's favor.

One starts out handicapped when buying a new trailer because of the tire brand and the fact that they aren't balanced. What happens during the tow to the dealer is another factor, as in were the tires inflated properly and was the tire speed rating adhered to? One of the first things I did was change the tires and install a wetbolt kit when I got it home. Maybe not wallet comfortable, but comforting for the psyche.
