One can whine and complain about the use of the various tire types. But that does or change the fact that each is designed to do a specific task. It's suitability for that task is nothing more than opinion and rhetoric.

STs and LT do not operate in the same environment. LT are subjected to turning torque, acceleration torque, and day to day wear and tear to name a few. That is why they are tested to these and other requirements.
STs are designed and tested for straight tracking, lower rolling resistances and less sidewall flex and other trailer needs.

Why Use An "ST" Tire
"ST" tires feature materials and construction to meet the higher load requirements and demands of trailering.
The polyester cords are bigger than they would be for a comparable "P" or "LT" tire.
The steel cords have a larger diameter and greater tensile strength to meet the additional load requirements.
"ST" tire rubber compounds contain more chemicals to resist weather and ozone cracking.

"Trailers will be more stable and pull better on tires designed specifically for trailer use. Since Special Trailer (ST) tires are constructed with heavier duty materials, they are tougher than typical passenger vehicle tires."
There is NO independant tests that would verify any of it.
There are no independent studies to refute them either. Just sayin. Internet posts notwithstanding of course...
Industry claims are just that, claims.
Just like a TT or car salesmans claims are... And they carry the same weight with me. A healthy dose of skeptiscism whenever someone is after my cash.

I often see "curbing" listed as a primary reason that ST tires fail..
I find this laugable. I have an old Blazer that I drive to work. When leaving it is easier/faster for me to drive over the parking curb than to back out and go around to the exit.
Since I am ALWAYS in a hurry to leave work. That Blazer has had it's LT tires curbed DAILY for over 20 years. No tire failures either.
Yet we are told that curbing an ST tire once will cause a failure!! JUNK.

You will never, ever know how often or by how much someone's ST tires ran over 65 mph, or how often they were under-inflated, or how often they hit potholes or speed bumps at speed, how often they turned 90 degree corners on pavement, or how often they ran on road shoulders, etc. How close were they to their max. load capacity rating? Internal damage from heat due to under-inflation and/or excess speed is cumulative and it can be many miles later that you have a failure and thus you can't relate the failure to what you recently did. If you bought a used TT, you can't possibly know how the tires were treated.
If you live on the west coast, you will never know how much the delivery guy drove over 65 mph or how many potholes or big cracks in concrete slab highways he hit. Your brand new TT can have over 2K miles on used tires in unknown condition. We followed a delivery guy last year in Ca. and saw how he treated the TT tires.

Before china made any of our tires ST tires we called them ST tire bombs......for good reasons.
Then ST tire production was moved to china and naturally morphed into china bombs.....for the same reasons.
Not all tires made in china expire at the rate the ST tire does. We have some very good china made P and LT and heavy truck tires out here on the road.
JMO....... Carlisle who is the oldest ST makers out here saw the light and redesigned their ST tires with the Radial Trail RH. The RH lost that rounded sidewall/tread profile and now looks more like a LT tire profile and its higher speed rating.
Now several (not all) ST tire brands have the higher speed rating. At some point maybe all ST tires will be the new redesign with the higher speed ratings and can run for 7-8 years at 50k-60k like the LT tire.
Once the ST tire has reached that goal then we can drop the china bomb tag. Only years in service and miles in service will tell the rest of the story but i'm betting companies like Carlisle and others can make a ST tire that can equal the LT and P tires we use on trailers.

It would be impossible to compare LTs to STs data because they operate in two very different worlds.
