Thank you very much.
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.
