Sailun Tire Failure

You won't see American made tires that are two years old with the sidewalls blowing out.

And

Chinese tires are junk.

These type comments aren't made from anyone that has been around the industry using LDT pulling heavy GN/pintle trailers....or even pulled several heavy rv trailer for many years or miles.
Facts are Some of the better P/ST/LT tires on the road are made in china.
Lots of newbs to the trailering world come on a rv website and read about all the issues with chine made ST tires we were having especially some years back...then assume all china made tires are junk.:R
With over 1.2 million miles hauling LTL with LDT and these type tires and trailer sizes I and others have had the same issues pop up with all USA brand tires....rare but this can show up running that many miles. I personally have had more issues with Goodyear P...LT...ST tires but I'm not ignorant to say Goodyear makes junk tires.

Yeah the American made G614 load G have the worst record of the G tire lineup although to their credit Goodyear has worked hard at making it a more durable tire and they have improved the last several years.

Other USA made 16" G load tires recommended for trailer service....haven't heard of any. There are several off shore made 16" G tires carrying old USA brand names like Gladiators......Hercules....others....which around here were mostly sold around small town stores...feed stores...grain elevators. Farm and ranch operations which also catered to construction types.

Maybe the OP can shed more light ??

Not sure what additional light I can shed on it. The DOT on the tire was three months old at the time I purchased it, as were the other three. This new replacement is 4 months old.

Close to 5k on the failed tire, its been run in 20 -100 degree weather, just over 2 years . Based on the weight of my trailer , average weight on each tire 2625. Granted thats not each axle being weighted separately , but a tire with a 4400 lb. rating ,its save to say I was far from overloaded .

I will go out on a limb here, there is argument to inflation charts, some say follow ,some say not. I run them at 10 psi under their max load inflation of 110 psi. I inflate my rear tires on my truck to 80 psi, when warmed up they are at 86-87 . Its save to say those Sailuns are running at least 110 psi when warm. I know they are designed to run 110 plus when running, but running them 10 psi under ,IMO has no effect on them ,nor did it have anything to do with the one failing.

Here is what I think, and I repeat. I either ran over something, although we could find nothing in the tread area , puncture, nail, whatever. Inside , or out. Or the jagged edge of a pothole got it, the damage is just below the tread area. The potholes were not minor, they were deep ,and rough, and there was no way to miss them all .

Other then a defective tire, no other clue, it was 100 psi when I left Las Vegas, I went 80 miles before it failed.
