Absolutely!

Another thing I would do is check the reserve load capacity you have. Weigh the trailer and compare to rating on the tires. You want at least 15% and more is better. We have about 30% on ours by upgrading a load range. Some manufacturers put tires on that have little to no reserve capacity. If you get side to side weights, can even be overloaded on one side. Anything that causes internal heat (too fast, under-inflated, overloaded) damages ST tires. Damage is cumulative and one day, bam, you can have a failure for no apparent reason.

I always find these threads interesting!
I run LT tires on my 5er, they came with LT which I replaced at 12 years old, towed home from dealer with them 8 years old and all looked fine.
Every time we start talking blowouts on ST tires the blame goes to the following, brushed a curb, jumped a curb, hit a pothole, etc. Well do you have blowouts on the TV with LT tires after the following, brushed a curb, jumped a curb, hit a pothole, etc?
This is exactly why I run LT on my 12,360# GVWR 5er, the tires have a combined capacity of 12,168#, BUT the axles will only carry a max of 10,000# loaded to max GVWR. This provides me with a 17.8% "Reserve Capacity".
I see the only thing "Special" about ST tires is that they are build to a lower set of standards than LT tires.

In addition there is no ST semi tires, all HD truck tires are built on the same carcass just different tread pattern for different applications. truckers may move a wore set of steer tires to a trailer to get more miles out of them before having capped. Then may be capped as drivers or trailer tread (caps not allowed on steer axle). The trucker may move drivers to a trailer for more miles before capping.

Sailun ST S637's nothing special there, beg to differ

GY endurance on mine and Son’s boat trailers for a year zero issues. 6 years minimum before I think about replacement. They have a stellar record being on the market for around two years.

A stellar record, wow what a claim for a tire out on the market for less then two years. We know how the G614's turned out when they came on the market, and still read about issues with them.

Somebody has to be the guinea pig on them. I think when these Endurance have been on fifth wheels , and loaded to their max rating, and ran down our roads for 5-6 years, and we get same reports we have had with the Sailun S637's, THEN we can make these stellar comments , but until then we probably should say ,so far so good.

Hopefully they will turn out to be a quality tire, unlike their big brother the G614. Never priced them ,but hopefully they are not gouging the consumer like they are doing with the G614.

Not so sure about this "reserve load capacity"

So you are not supposed to load to the tires MAX load carrying capacity???

You CAN if you don't care about increasing the risk of a blowout...

Note that running ST tires below the max. sidewall psi reduces load capacity rating (per load inflation tables) and thus reserve load capacity which a factor in increasing the risk of a blowout.

For those not familiar with reserve load capacity, the RVtiresafety.net blog has some good info. here and here.

Not so sure about this "reserve load capacity"

So you are not supposed to load to the tires MAX load carrying capacity if that is what your load really is???

I think that Duro's are the best tires coming out of asia, they look to have the blackest rubber color,wich means they have a lot of carbon black, and they have lasted the longest of all trailer tires I have ever tested...And I never had a blowout with them..I highly recommend them..

Whoda thunk?

Ive never known to select a brand of tire based on color? Perhaps someone should come up with a blackomometer.

Define "blow-out"

Good question. When we had our "blowout" or what we thought it was. I sent detailed phots of the tire from differnt angles to an RV tire specialist and he determined that we did not in fact have a bloweout, but tread separation.

I've seen more than a few people happily driving down the road with a flat tire on their trailer and after it gets so hot and blows apart they too have a "blow out."

And if you were following them before the tire let loose you most likely would have seen them pull over on the shoulder somewhere, or they were happily weaving with the curbside tires going over the white line onto the shoulder about every mile. Take a mile walk on an Interstate shoulder sometime. More hardware than aisle 12 at Lowes and you'll probably come away with at least 1/2 a dozen rubber bungies as a bonus.

100% on the money! And you're the only one that talks about this Ralph.

Back in the day a friend was working on a NASCAR team. It was just him and a driver. The story goes my friend never got a flat tire traveling around the US with the truck and trailer. The driver of the race car was always getting flat tires. He was like WTH? My friend would tell him stay out of the %#$%@$%@ gutter and you won't get any flat tires either you dumb @!#!

Ralph, I completely agree about people wandering into the shoulder and just how much ”stuff” you can find there. I spent many years as an emergency roadside assistance provider and changed many flat tires for motorist on the side of interstate 80 as well as other highways. After sending the customer on their way, I would often take a minute as I gathered up my tools and look around on the ground at the assortment of nails, screws, metal brackets from God knows what, pieces of exhaust system, and even the occasional broken cell phone.
