Another Sailun Failure

Add me to the list of Sailun tire failures. We have a 2018 Fuzion 357 toy hauler. Tires dates are late 2017. ST235/85R16. Lat Friday morning, two miles down the road on our way to a camping trip and the driver side rear sidewall blew completely out, (dual axle set up). Checked tire pressure before leaving approx 107 PSI when cold. Waiting to get the rig in to a dealer for damage estimate. Bottom skirting destroyed and it also bent the outer frame of the kitchen slide out.

Do you have a TPMS? If so, did it give you any warning?

I do not have a TPMS. We were only two miles down the road so I think it was going to happen regardless. Just a tire/sidewall failure. Funny thing is the rest of the tire,(excluding the sidewall), is in very good shape.

One of the things that almost no one talks about on these tires is the loss of load rating based on age.. If I remember correctly it is something like 10% per year.. So in say 3 years a tire good for 4,000 pounds when new could potentially be only good for 3600 after a year and after 3 years.. maybe 2800 pounds...

Maybe one of the tire gurus will chime in and educate us..

Maybe why moving up a load range is beneficial.

Any All-Steel Tire

"A zipper rupture is a spontaneous burst of compressed air that can occur in the sidewall/flex area of EVERY steel cord radial tire."

That's a description of a sidewall failure of an all steel radial tire.

I' don't know what caused you tire to fail but it sure doesn't look like a typical sidewall failure.

I tend to agree with CWtheMAn. Doesn't look like a sidewall flex failure from run low. More likely a belt separation.
Might have been discovered if a "Free-Spin" inspection had been done in the last 500 to 1,000 miles.

I hope my tires don’t loose loss of load capacity at a rate of 10% a year.. if so does that mean my rear tires on my Duramax have lost 30% of their rated load capacity since they are now turning 3 years of age?

My G rated tires just saw their 5th season of use... covered when not towing.. I’ll just have to rely on my eyes, my experience, and gut hunch when it comes to deciding when to replace my truck and RV tires...

Javi,
I think that's the first time I've heard this - hope it's not true! Any idea where that came from? Do any of you tire guys know if this is true?

In the short time sisnce the failure, with the research I have done, I cannot find a "heavier" load rating than a "G" rating for the ST235/85R16 tires that are on my rig.

Anybody out there with more knowledge than myself about tires know of a tire manufactured that has a heavier load rating? I would appreciate any input on that!

I think you're about to run into a brick wall with a search for higher rated tires in that size wheel. I've never see a 16" wheel that's rated greater in pressure and weight capacity than the ratings for the tire above. So, even if you did find a tire rated higher, where are you going to find a wheel to install it on ????

It becomes a "double edged sword" of finding not only the tires, but also new wheels...

My last 5er came equipped with Goodyear Gs with no issues for 50-60k miles. When it came time to replace I did so with 17.5" H rated Sailuns ordered mounted on nice aluminum wheels shipped to my door for less than I could replace the GYs & had good service with them up til I sold the 5er.
