ST tires are the best

ST's are not tested to the same standard as LT particularly with regards to speed. All of the ST's I could find were made in China and they do not have a good reputation.

Maxxis is not made in China.

This is not true on many trailers. If a manufacturer has a train car load of ST235/80R16E tires and rims from Tredit or Tireco, they install those on many trailers with 5200 and 6K axles also. The GAWR will reflect the axle capability not the higher tire rating. The placard will read ST235/80R16E rated to 3420 @80, but the GAWR will be 5200 or 6000, or less in each case if they want.

This is the real catch twenty two situation that many are in, as the marketing of ST tires has gotten retail tire shops convinced that they can then only install another cheaply made ST tire at that rating.

No one has produced a law that starts that! Just documents that say "should", but not "must"!

There is a lot of confusion between what must happen at original sale and what a consumer can do after a purchase. Those that market the cheaply made ST tires try to push what must happen at original sale onto those that need or want replacement tires after the purchase.

Additional, many manufacturers are building trailers to the highly inflated ratings of ST tires. Keystone routinely derated 7K axles to 6750 so they could push the trailers out the door on ST tires rated to 3420 each, giving a full 90 pounds of extra capacity per axle. A trailer can easily be out of balance left to right on an axle or between the axles more than that amount.

These are trailers that are screaming for LRG tires. However Goodyear for years has held the price of their G614 LRG tire above what trailer manufacturers are willing to purchase. And trailers where equipped with wheels rated to only 80 lbs. Enter Sailun with the S637 LRG all steel ply tire with a price point and quality that is affordable. Gladiator also has a QR35-TR(AS) {AS=All Steel} that is fairly priced. Note that they also have a QR35-TR that is a poly carcass tire, so watch for which one you purcase.

Do you use the actual load rating limits if you are using LT tires?

Yes
The placarded weight rating on the sidewall of an LT tire should be the actual load rating limit assuming you run them at the maximum psi shown on the tire sidewall .
In most cases the axle weight rating and the wheel weight rating are higher than the tire rating .
On OEM trailers 99 % of the time the tire rating ( times 4 ) is the gross vehicle rating for the axle GVW placarded on the trailer .
Tires are the weakest link 99 % of the time .
RV wheel manufacturers list their weight rating to coincide with the maximum tire rating at the maximum PSI rating for the OEM tire .
Steel RV wheels are not placarded for PSI in 99 % of the cases .
Some steel RV wheels may have a placarded weight rating , but not a PSI rating .

This is what waiting to replace my tires did to my trailer 3 weeks ago. Had a TPMS on at the time and the tread just came off.The tire deflated shortly after I stopped. I noticed the tread flying immediately and pulled off the road. Total flop time was no more than a minute. Damage is cosmetic, but ugly none the less. The Trail Express Power Touring oem tires were replaced the next day. The manufacture date was July 2011 and only 3500 miles. No way should anyone ever trust these tire.

No, that is the body ply - likely polyester.

That tire does not have a cap ply.

What you are seeing on the shoulder on that tire is the ply. The main problem with ST tires are none of them have the "nylon cap" that every other tire on the road uses now post "Firestone Fiasco". That cap keeps the belts from separating.

The Nylon cap was added to the GY Marathon years ago and to the PowerKing TowMax and Carlisle Radial Trail RH in recent years. It did not " fix " the Marathon and jury may be still out on the others. I believe the TowMax is still having issues.

Michelin does NOT claim a Nylon cap on the highly regarded XPS Rib, however the Duravis R250 has one.

Nylon cap is NOT a good hat rack. Chris

So this goofball does a video and does NOT compare EQUAL size tires or even all new tires .
The tires used were not equal in size or age .
Why compare a used P tire to the new Load Range E ST tire ?
To make his visual point , of course .
The guy in the video used the largest highest capacity ST tire for his comparison !
And a smaller LT tire and P tire .
He used an ST 235/80 R 16 load range E tire to compare to a smaller LT 225/75R16 tire in his example .
He did not show a sidewall flex test for the LT tire .
He skipped right over that .
And he used a completely used up P tire for his sidewall flex grab for the P tire .
I discovered this by correlating the sidewall weight rating for each tire in his comparison .
Further , this bozo did not understand that an ST tire has a considerably lower threshold to meet its standard .
That is why the ST tire confusion continues except for the motorheads who take the time to research the subject .
For proof :
The only ST tire placarded at 3420# on the sidewall is the ST235/80R16 load range E . "For Trailer Use Only "
The only LT tire placarded at 2680 # is the LT 225/75R16 load range E . No restriction.
There are several sizes of P tires that are placarded at 2403 # such as the tires that fit a Honda Civic CRX .
So this Trailer Life goofball does a video and does not compare equal size tires or even all new tires .
This is deception at its best .
