Settle a "tires" issue

IMHO, IF those Michelins are really new (read the date stamp) they should be good for 4-5 years. I've seen posts by folks who've had them blowout (Montana forum), but not many. The problem with ST tires is they almost all are rated for only 60 mph, so check the fine print on your tires and don't exceed the rated speed. This is the biggest reason I believe in LT tires on any trailer. They also have more reserve capacity that ST tires don't and are built to take more abuse (think of what trucks go through vs. trailers).

One thing about these "free for all" forums is one can get really confused after reading all the various opinions. Most of which are based on opinion over engineering and physics of facts. One never graduates from the school of hard knocks, so be ware.....

To Me Again --- checked my Mich's, the only additional markings/info on the tires include: Radial and M and S2 -- nothing anywhere indicating LTX or XPS just Load Range E. 3040 Lbs @ 80 #pressure. Not sure where else to look. WB

Provided the tires will handle the weight, I certainly wouldn't replace them after 2 years of service. That's foolish IMO. They should be good for several more years of service easily. But again, that depends on whether they are rated to carry the weight you have on them.

Thanks to all the comments made in response to my post on LT vs ST tires. Yes my tires are Mich 235/85/16E's not 285's. My typo error. I have taken all comments to heart and truly respect what all have written. The tires are 2016 products and I WILL replace them for 2018. At present I seem confident the replacements will be the new GY Endurance ST's. The verdict on their reliability/performance should be in and any bugs worked out. I tend to be conservative on weight; always travel with VERY little fluids in all tanks on board and keep "extras" to a minimum. Just pulled the wheels checked all bearings/breaks. I inflate the Mich's to 78 lbs cold and NEVER go over 65 even downhill with a tailwind --- enjoy the journey and always allow extra time. I traveled 7K miles in 2016 and will total about the same in 2017. The Mich's have performed very smoothly and show VERY little wear. I just came down from Maine yesterday and passed at least seven 5er's pulled to the side with flats (some with multiple flats) on ME 95, Mass 495 and 90 and CT/NY 84 on my way home. So there is serious need for all to check their tires. Again THANK YOU to all and happy trails. WB

You still have not provide the model of the tire LTX or XPS Rig. At any rate they should be good for 6 or 7 years of use on a trailer. I ran Ribs for 6.5 years as one was 8.5 years old from manufacture date and the other three 7.5 years. The one that was 8.5 years old was getting small cracks in the sidewalls. They had around 44K miles on them and I sold them on CL for 200 bucks with around 60 percent tread remaining.

Anyone that thinks a ST235/80R16E poly carcass ST tire off the rim has a stronger sidewall has never handled and compared it to a LT tire, particularly to a XPS Rib or R250 all steel carcass tire(which are the best two tires available for 5200 and 6K axles).

There is a lot of marketing hype surrounding ST tires that does not pan out in real life.

The new GY Endurance ST is to young to make final judgement on and Carlisle continues to tweak it's ST offering. The new Endurance is the only ST tire I would recommend at this point, which is based you GY commitment to making a good tire for trailer only use.

You justify your reasons for running what you want to run and I'll justify the reason for running what I want to run. I'm sure on a commercial trailer with dual wheels/axles there isn't as much stress on the tires/wheels when turning because of having a second tire close helping carry the weight as there is on a tri axle setup with single wheels/tires. My personal opinion is I don't want LT tires on my trailer and I gave my reason, you don't have to agree nor do you have to approve. Not trying to be mean or crappy but just expressing my opinion. My trailer also has the Sailun S637. If a person runs a good quality ST tire in my opinion there is no need to run LT tires. End of story!

Actually you are running an LT tire: the Sailun S637 started life as an LT tire. I know because I have a set on my toyhauler and they are labeled "LT", but with a caveat: they do say "For Trailer Use Only". As was mentioned they changed to an ST designation without changing the overall manufacture of the tire.

True for a tandem dually axle trailer (rv and non rv) but Commercial trailers I referred to were the same tandem and triaxle set up like any rv trailer using the same axles/wheel and tires.
I have the Sailun S637 LT G on a 36' GN triaxle stock trailer with three 7k Dexter axles. However these Sailuns came from the transitional era when the S637 LT and ST were the same part number.

However the OP 26.5' 5th wheel doesn't need the Sailuns so were just flappin' our jaws talking about a commercial grade all steel carcass tire which has nothing in common with a ST E/D/C tire other than being black.

LOL...good one.
We don't find this to be true our here in the commercial trailer world using 6k and 7k axles. Guess some how its different for your rv trailer. However the highest rated 16" LT tire is the all steel ply carcass commercial grade Goodyear G614 RST in a LT235/85-16 G at 3750 lbs for 6k-7k axles.

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! **

Now you can worry about rolling those soft sided tires off the rims :R

You justify your reasons for running what you want to run and I'll justify the reason for running what I want to run.
