Sidewall Information Help

I was checking out my trailer tires and noticed differing max PSI info. There is a section with load C and max cold psi 50. Then on the other Safety section is never exceed 32 PSI. I'm new to towing and don't want a blow out. They came with a pressure of 38. What's the difference in those numbers? I'm hauling a 3000lb boat with about 500 pounds of gear in it.

I have Carlisle Sport Tread 225/75/D15 if that helps any...

The max is the pressure to use, 50. And it should be kept at that pressure. I believe the 32 is the max pressure to use when seating the bead. Even on TireRacks site, in the information section, it states never exceed 40psi when seating the beads, this for any tire.

Thanks for the info. I've been running them way too low then. I've taken several long trips with the pressure under 40, lucky I haven't had a blow out. Have I done any harm to the inside of the tire or will I be good after I inflate to 50?

If they haven't already blown, they probably are okay. However, if you do not have a spare, I would get one. never know when something will go or you hit a nail etc.
