I dont understand tires!

Same here on all counts (14K, Sailun, MOR/ryde IS).

Whatever tire you get, put TPMS on them. Might save you damage from a blowout next time.

Regardless of the tires selling points or weight ratings, simply pick one of each up and observe the differences for yourself

It was quite the eye opener when I had the E-rated ST garbage pulled off my trailer and replaced with a set of Bridgestone Duravis 250s. No comparison in terms of weight, sidewall thickess and overall build quality.

I will replace all 4 tires but I read about Goodyear Endurance ST and LT tires as well as Sailun s637. I do not know the difference in ST or LT? Or the Goodyear or Sailun?

You have a lot of potential cargo capacity for a couple of 6000# axles. I suspect you have the standard ST235/80R16E tires and may have pushed their limit with an overloaded axle. Sorry, just guessing. Find some scales and prove me wrong.

You’re not going to find a true Light Truck (LT) with the load capacity necessary for replacing those original tires. Your best option is to use the same sized tire and go up a couple of load ranges to load range G. You’ll most likely have to change wheels but the all steel cased LRG in that size is an outstanding trade-off and you won’t have to use the full 110 PSI inflation pressures. Somewhere around 95 PSI will provide more than the necessary load capacity you need from the replacement tires.

Wrong, Firestone/Bridgestone is NOT a Michelin company. BF Goodrich is, you may have confused the two.

Problem seems to be that many tire dealers refuse to install a LRE LT in the place of a LRE ST, having drank the ST Koolaid. Chris

You're right, Chris. Don't know why I keep forgetting that.

Tire dealers simply won't replace a tire with =less= capacity on the sidewall than the placard states, even if the replacement is demonstrably better. No problem if you're going =up= in rating, usually. Only way 'round it is to take all the wheels off yourself and schlep them to the dealer to mount and balance. Total CYA policy driven by the lawyers.

To answer your question. ST is Special Trailer. Built to withstand the large amount of pressure put on the sidewalls when making SHARP turns as we do when parking trailers.

Right out to the old ST propaganda manual. If they lived up to their claims they would have not self destructed at such high rates over the last two decades.

The GY Endurance may be a game changer in the ST tire offerings. Time will tell.

Assuming you have 16" wheels, 2 great options would be Michelin XP Ribs or Bridgestone Duravis R250. In reality, they are virtually the same tire (same company) but the R250 is usually about $50-60 cheaper per tire. All-steel construction, tread and sidewalls. Yes, they are LT tires and you could push the envelope on their stated sidewall loading, but they are far and away better than any ST, IMO. While the Sailun seem to be great tires, they're overkill for a trailer of your GVW.

We’ve run Sailuns at 105-110psi for the last 2yrs on our 14000lb 5er and are very happy with them. A little overkill but I’d recommend them for the peace of mind. They haven’t “beat our trailer to death” but we do have MorRyde IS also.

What size tire? What is the trailer GVWR?
