Saliun S637 Tire Pressure
Dumping the Tow Max tires this week and replacing all 5 with the Saliun S637s 235/85R16 (G). My question is do you run them at the Max PSI of 110. I have a Big Horn 3260EL when loaded weights 12,6...

I have always ran my tires at indicated max pressure but using a weight/pressure chart does make some sense. One thing to consider is the higher the tire pressure, the bigger the boom when a tire does go. My last camper came with "D" (65 PSI) rated tires. I would get a blowout around once a year which was getting tiresome (pun intended) doing roadside changes...which I got really good at by the way. At one point I upgraded all the tires to "E" rated and ran them at 80 PSI. Still got blowouts, the only difference was when these babies blew they started to do some damage to the trailer as they would totally separate the tread. I lost both fender skirts with those "E" rated tires and towards the end of having that camper I dreaded pulling it anywhere. Once I reached each destination without a blowout (which happened more than not) I would celebrate a little and relax!! I would hate to be around a tire blowout explode at 110 PSI...that is crazy. Maybe I have been doing it right for the last 15 years running max pressure, maybe not but I will be doing some more investigating.
