Couple of things here. We had a blowout on our fifth wheel recently and we have a TPMS system. No warning and I had just looked at the screen, when boom!
Just a little bit of a tangent here since I am in the market for a TPMS - can you tell me what brand / model you have?
TST Systems.
Two things
1) A TPMS would not have warned of the incident in the OP photos. The tire still had pressure. A TPMS could actually increase damage because the driver might not think something was wrong with the noise or what he saw in the mirror because the TPMS showed regular pressure.
A TPMS would have shown the driver if the tire was being run at low pressure or high heat previously. As noted in several posts - the tire could have been damaged by those in the past, and be at normal pressure/ temps at the time the actual tread separation happened.
Running a tire at low pressure for several hours could start a problem which won't reach a failure point for a long time. And with no warning. That is why you need to check the tire, by feeling the tread area for bumps and bulges before you start towing.
2) A TPMS warns of a developing problem of pressure and/ or temperature. A road hazard tire failure - i.e. running over a piece of debris - can happen too fast for a TPMS to warn the driver.
If a tire has a blowout and loses pressure, the TPMS will alert, but it may be too late to prevent. If a tread separates - the TPMS will almost always not alert.
Does not matter which brand of TPMS.Me Again wrote:

Tell me why the magic Nylon cap has not made the GY Marathon the top of the line of ST tires? We are talking about a major tire company that added the Nylon cap to the Marathon in the late 90's!
Maybe it is all about tire weight and the related construction. Look at the Mx brand weight compared to the other ST tires.

Weight of tire does not translate in to reliability. A 3 inch nail will blow out any of the the tires listed above......- When we were in the market for tires for our HTT a couple of years ago - before Rocky - our local, reputable tire dealer suggested Westlake. We'd never heard of them, but he said he'd sold many sets with no problems reported. But.....at the time, there was a thread running re tires and several reported problems with Westlake, so we went with what we'd had excellent service with....Greenball Transmasters. They were OEM on our HTT, we replaced at about 4 years with the same and then at 3+ years due to a long trip scheduled. FWIW, DH is diligent about checking torque and tire pressure before we leave the driveway and repeats if a longer trip. Also, it's very rare for our speed to exceed 60 - 62MPH. Have no idea what the OEM is on Rocky, but when the time comes for new ones, Transmasters will get another good look. Will also consider LT vs ST.
To the OP....do you know the true age of these tires?? Because the trailer is a certain age, does not mean the tires are the same. They could have been sitting in a warehouse for a couple of years or more, making them ready for replacement a year or so after they were put on. Suggestions for replacement age varies by post, but most say 4 - 5 years. We're on the 4 year side as extra precaution. Sorry for your friends experience. CKNSLS wrote:

I have never read that ANYWHERE. An awful lot of high end TTs come with LTs, and many of us have upgraded to them....
The ad propaganda from the ST tire makers are/is careful in their wording around this subject.... They NEVER state that LTs can't handle it.... They do imply that ST tires are especially good at it.
That doesn't mean that LTs fall short of the job.
Big difference.
I often wonder how overtired some of these TTs that have LT tires are and if that compensates for the resistance to the flex and scrubbing issue. In other words how would a side to side comparision of say an LT tire with the same load capacity as an ST tire do on the same trailer.

If you were to read my history of ST tire use, you will find that I upgraded sizes and load ratings several times in an attempt to make STs work.
I have much more experience with STs than LTs. I have owned more sets of ST tires than I care to remember. I am on my second set of LTs, having replaced the first set due to age.. Something that I never had to worry about with ST tires, as my TT was constantly sporting brand new STs. My LT experience started in 2006. Not a single failure since I made the swap. And I am much rougher on these tires, as I don't worry about them... No excuses. They just work.fla-gypsy wrote:
If you have the space and wheel size for LT tires they are an alternative. If you don't there are better choices in ST tires that can be very successfully used. I have used ST tires since 1998 with great results.
I've got your beat by about 3 years since I ran GY Marathons exclusively since 1995 up until last year when I decided to get fancier rims and went the Kumho 857 route. In fact both the trailers I have had since 1995, one from 82 to 07 and this current one from 07 to present ran 14" ST tires that were loaded on the first trailer within 250lbs of max capacity on each tire (6K to 6,200 lbs) on 205R75x14 STs and on the second to within 100lbs max capacity (6600 to 6800lbs) on the same sized ST tires. I switched to the Kumhos mainly to get a little more reserve capacity since it just made sense to me and to get around the 65mph speed limit when needed. Plus I got the fancy aluminum rims that I always wanted and ditched the mediocre steel white painted spoke rims.

Yep, me to.
I and many others EXPECT the TT tires to be as reliable as the TVs tires, under the same conditions. More weight? so what. Get a highr rated tire, and it should be reliable. If it's not,,, then there is a problem that needs fixing.
I won't make excuses for tires. They either perform to my expectations, or they are gone.2oldman wrote:

Like I said, why should I have to expect less from a trailer tire when it travels the same road as the TV.
That is understood and situations may vary. There are many cases, like mine, where switching would make no difference and the weight would still be well within the tires handling capability.
It's not a decision that may be in everyone's best interest. Brand and other factors have more to do with price than just being an ST or LT. Besides that, the general design is different. More weight - more heat generated. The ST tires are designed to displace more heat than an LT. You have to ask yourself how close you are to max capacity and how much heat displacement means to you. There are other differences besides load capacity and heat displacement.
