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.

I've had long e-mail conversations with both Alan and others at TBC Brands (the US distributor for Sailun). I am very confident they will tell you the same thing they told me:
1. The Sailun S637 tire is often sold to commerical truckers who will almost always inflate the tire to 110psi. And they do this for one simple reason - they just do not want to take the time to adjust PSI for each load. So most commerical users inflate to 110psi.
2. Now RVers are different and here is what they recommend. When you have your trailer fully loaded and attached to the truck - weigh the trailer axle load.
3. Use the Tire and Rim Association tire inflation tables for your load to determine PSI. Add 10% to that number and inflate tires to that psi.
4. And almost without exception that last thing they mention is use a TPMS.

I too had a lengthy conversation with Alan on the phone, he sent me the Sailun inflation chart, which I posted without much luck :(
There is a lot we went over with this tire failure , to make it somewhat short, it was not a blowout, or defective tire as far as both of us were concerned. It was either a puncture ,and slow loss of air, or a jagged pothole got it.
He explained the inflation , and if I thought my trailer rode rough at 100 psi, I don't thing it does, with how things are inside , or does it have any cupping or unusual wear , and it does not.
According to the inflation chart , and my trailer weight which is right around 13K, minus the pin weight , puts me just over 10K on the axles, now if they are equal ,and of course they are not , that puts around 2500 per tire, which only requires 45 psi on ea. This came from Alan before I had been sent the inflation chart from him . I will continue to run 95-100 , I see no problem with it, and he didn't either if the tires were wearing okay .
