Sailun Tire Failure

This is why I use the Goodyear endurance and only recommend American made tires. Chinese tires are junk.

Looks like the sidewall let go. Curb damage perhaps? Who knows? I sure like mine and will continue to use them.

The second failure in many years, so not too bad. Thanks for posting this.

I agree, the second one I know of, mine being one of them :B

I don't think its was a defective tire , too many miles, to many rough roads, I think a pot hole got me, they were bad in that section of road . Found a new Sailun in Kingman, good price, four month old tire . All is good .

I also will continue to use them.. Actually after hearing from a friend that runs them on his fifth wheel, and he also runs the Sailun Terramax AT's on his truck. He full times, and so far they have been great. He tows a big fifth wheel. They will be my next truck tire.

The one thing I will do is replace the tire behind the one that failed, the one that failed was the front tire drivers side. Although I ran that tire another 200 miles to Yuma, I fell like its been a bit compromised , I will make it my spare. My spare is actually too old to use, yes my bad.

I actually got pulled off the road pulled off the failed tire, unhooked the fifth wheel, loaded up the tire went to Kingman for a new one. It was a long day .

It is hard to comment on this without knowing the history of the tire. Every tire Manufacturer has had blow out-- some more frequently than others. Pot holes, road hazzards, exceeding speed rating, loading, alignment and other factors can mitigate a tires life. I have Salins that replaced Goodyear G rated tires that wore out after 60K miles. So far they are performing as well as the Goodyears after 10K miles. I drive under 65mph and they are not near over-loaded with tire pressure at 105PSI. No pot hole or road hazards so far. BTY trailer suspensions are the weak point between the truck and trailer.

2 years old . Close to 5K on them, always been inflated to 100 psi. I run pretty consistent at 65 mph. Left Las Vegas that morning for Kingman ,Az. 20 miles outside of Kingman is where it happened, after trying to miss 10,000 pot holes :( Pretty nasty road off ,and on all the way to Yuma .

Neither felt or heard if in fact it did blow out. IMO it did not. There has been mentioned curb damage, no hitting curbs, no scuffing against curbs ,etc. Plenty of bad roads though.

Nothing I was aware of in the road that I hit, other then all the pot holes that were pretty hard to avoid. When I seen it in my mirror I initially thought for a second it was a bearing, it actually looked like the trailer was on fire from the amount of smoke, but could see pieces of tire flying off. IMO ,and far from an expert , I think I had lost air from a leak, and the missing section of tire was the process of the tire coming apart

Possibly a pot hole could of cut it, and a sudden loss of air, and then started coming apart at the section of the damage. Not a scratch to the fifth wheel ,other then some small pieces of rubber stuck to it. Rim was undamaged.

Trailer was weighed partially loaded 12,740. Pin 2420. Loaded for this month long trip possibly 13,000, -13,200. 2700 on the pin. Far from overloaded for 4400 lb. rating . We could add a few hundred to those weights before near overloading.

I was told years ago that most blow outs are caused by a slow leak. The tire starts going down, then starts to flex. This causes the tire to heat up raising the pressure to the point of failure. He pointed out the finger sized hole in the side of my BFG Mud Terrain tire that was destroyed. That was where the air left.

Be curious to hear how Sailun handles this. Supposedly good tires. I know a number of people with 17.5 Sailun tires with very good service.

It was bound to happen, and it did. Any experts want to weigh in? Luckily, no damage to fifth wheel or rim. 2 year old Sailun S637 , inflated to 100 psi.

I would reach out toSailun, and see what they have to say. Keep the tire as they may want it to determine what caused the failure.

Yeah, I noticed that too. My Carlisle tires literally exploded and caused quite of bit of trailer damage when the tread blew off.

I think that had to be a defective tire. A tire without defect that is properly inflated can handle being overloaded, over speed, and potholes without having the sidewall blow apart.
