Sailun Tire Failure
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.
Forum Discussion
To be honest with you all, I don't watch this forum closely. In fact a friend of mine sent me a link to this post.
After reading the posts, I was curious as to what Sailun reps would have to say. I reached out to a contact at Sailun and got this response:
I am the Segment Manager for Sailun Tire America. Thank you for being a Sailun customer and sorry that you had an issue with your Sailun S637.
I will try to be as brief and detailed with my reply as possible. I looked at the picture you included with your post. As other respondents indicated, it is difficult to fully analyze a tire failure from just a photo.
I will offer up the following. You indicated your tires are 2 years old. In my experience (30+ years primarily in commercial truck tires and retreading), if there is a manufacturing defect, it will normally rear itself very early (less than 6 months) in the life of the tire. So, I would like to rule that out.
In looking at the damage to the tire in your photo, the damage to the steel sidewall cord indicates the tire was run low on air (heat buildup) at some point in time. It may have been inflated to 100 psi during the trip you were currently on, however; the tire could have been run low at an earlier point in its life and the catastrophic failure may take days, weeks or months to occur due to the continued use under a compromised structure.
It is possible there was some kind of sidewall abrasion. Although, I would expect the failure to be more concentrated to a smaller area. Again, the damage could have occurred at an earlier point in time and the failure would be delayed.
In response to some of the respondents about Chinese made tires being "****", I would say it is the factory of origin that determines the quality of the tire, not the country of origin. Sailun tires are built in factories with some of the most advanced equipment in the tire manufacturing world. In fact, Mesnac equipment (a Sailun company) builds and supplies tire manufacturing equipment for many other tire manufacturers globally. Michelin, Bridgestone and Goodyear all have factories in China.
Our U.S. sales on the Sailun S637 ST are in excess of 120,000 tires per year. I have been with Sailun Tire for 5 years now and can count on two hands the number of warranty claims we've had. The tire works very well.
I won't go into load and inflation recommendations in this response but, should you want further information about the facts on load and inflation, I would love to provide details that you could post for all users.
