Trailer tires
We have a dual axle travel trailer with 13" wheels. On our last trip blew one of tires. I started doing some research and found that these are ST rated tires which I think means they are rated to 65 M...

I always weighted my trailer and truck when I've first load them (when the TT is new to me), or when first loading the trailer for the new RV season.
My post referred to some posters who say to only air the trailer tires to what the weight the trailer is carrying that trip. I always air my TT tires up the max sidewall pressure on the tire. If I actually only aired the TT tires up to the weight I was carrying, I'd have to weight the trailer each and every time I took it out. Sometimes what one is carrying in the TT is more or less than the last time.
And just weighing the trailer as a whole and dividing by 4 is no good, since each tire will have more or less weight than the other tires on the TT. Each and every tire must be weighed. Who has the time or facilities to do that?
As I said, I air mine up the max sidewall pressure. Then I've covered any changes in weight from trip to trip. And my trailer has never lost grip on the road due to too much air pressure in the tire, nor have I suffered from premature tire wear in the center part of the tread.

Re: #1) I don't ever plan on going to a scale and weighing each trailer tire in order to know how much air to put in it.
For a small popup or other very light trailer towed by a larger vehicle such as 1/2 ton or bigger truck I'd tend to agree it isn't necessary to weigh it.
Otherwise it is VERY useful to get your rig weighed at a CAT scale. Too many people underestimate the weight of their rig when fully loaded. They end up over the trailers tire and axle limit or over the GVWR of the tow vehicle.
The other useful thing to do is carry temp sensor. These are point and shoot devices. Simply aim at the tire immediately after stopping and get a temp reading. Quick way to tell if tires are running way too hot which happens when overloaded or under inflated.
