I’ll be selling the coach once I get there and buying a house. Just want to make sire the next owner is set as well. I’m dropping it for a few small repairs before I sell.

85 to 90 psi would be just fine with that weight but what is the ply rating, E, F or G.

They are G rated.

To use the ST prefix they had to change the carcass construction. It's the only way they could increase the load capacity between the two by 650#. Of course, that's the ST235/85R16 LRG. The ST235/80R16 LRG, being all steel, is probable a completely new construction.

Not from what I've heard from at least 3 different tire dealers and from what I've read in a couple different RV fora. Every time this has come up, they've all said that the STs were virtually the same at the old LTs, with only minor cosmetic changes to tread design and, of course, sidewall #'s. I've never cut them apart to check, though.

The off shore tire builders do not waste much time in being competitive. They have flooded the market with numerous brands building these two Sailun sizes. Even the grand daddy ST builder has reciently introducrd their verson of the popular steel tires. With retailers such as Walmart, Sams and Discount Tire providing them they will become popular replacements when the need arises on the road.


Look Here!

There seems to be an argument that the ST tire and the LT tire are the same design and construction. Per the post above your last one. They sure look the same.

You couldn't give me a Carlisle, I'm not convinced they're any better than the ones I owned some years ago. Maybe in a few years after they've been out for 4 or 5 years with no issues.

"The off shore tire builders do not waste much time in being competitive. They have flooded the market with numerous brands building these two Sailun sizes."

I'm not sure I understand what you're saying here. "Sailun sizes"?

In the first paragraph I identified the two ST steel cased tires Sailun builds. Carlisle is just a reference. The two tires mentioned are being built by at least another dozen brands.

Basic tire construction materials are displayed on the tire sidewall. The actual size and strength - tensile - of the cording is confidential. TRA oversees such things for the tire industry. Of course their information about the materials are also confidential.

\ The 16" Sailun S637 LT re designated to ST tire story from a dealer which mirrors what I was told by simpletire.com when I ordered my LT S637's. (paste and copy)

Here are some more observations on these LRG S637 tires...

Over the last 6 years or so, we have sold HUNDREDS of Sailun S637 tires in the 235/85R16G size. First the LT version, and more recently, the ST version.

Same tire, different designation.... and yes this change in designation was indeed done to beat the tariff on LT tires and keep them reasonably priced. The tire was not changed.

We have sold these tires for all kinds of trailers, Stock trailers for ranchers, Toy Haulers, RV trailers, Stacker car trailers for race cars, Open car trailers for hot shot haulers. There have been a bunch of repeat customers over the years, and for many commercial type users, this is the only tire they will buy.

My point is, if your considering the Sailun S637, do it. A year from now, you will be back on this forum telling others about how well these tires have worked for you!

One note of caution: be sure your wheels are suitable for the higher load capacity and 110 PSI pressure. This is important.

30 years in business on my own, with over 40 years of doing tires!

IN bold: NHTSA would not allow that and the TRA would not approve it.

They let GY get away with it on their G614 because they registered the tire name as Regional Service Trailer (RST) and put "for trailer service only" on their sidewalls. That made it unique.

Yet Sailun did it! So???

5 years! Imho

Well, since the "new" ST Sailun's are the same as the "old" LT Sailun's, what do you suppose they did?
