Tires can heat up from underinflation. They have to be really low on air to get that hot though.
You need to figure out why your brakes came on and stayed on. I think that is where you will find your problem.

No they dont.
I'm surprised you disregarded her second clue. The one about the hubs not getting hot. Or the third one about the tire spinning freely.
Both of those point to the tires themselves being the issue and nt the recent service, namely air pressure and weight distribution.

It's still unclear to me if it's only the rear tires that are heating up, and if that was consistently true for the whole trip. If only the rears were "hot" immediately after the seized brakes event but they were the same temp as the fronts later, I'd think the heat was caused by the brake friction (again assuming that's where the brakes are).
If only the rears are heating and the wheels are "cool", sounds like those tires do indeed have some kind of problem that may or may not be visible to the eye.
There are several common things that will heat tires:
1) Probably most common:
Underinflation- causes excessive flexing/friction heat buildup even at normal/lower speeds.
2) Speeds higher than the tire's rating, especially in hot weather.
3) Wrong type of tire for trailer(E.G.: passenger/light duty tire-sidewalls too flabby for trailer use, flexing /friction heat again)
Interior (invisible) damage can also result in heat buildup, and tires that have "aged out" may have such damage despite the look of the tire's tread/sidewalls.
Here's a pic of the tire date code location and how to decipher it: "16"= The 16th week..."04"= 2004

THis does not usually happen with tandems, but the rear axel could be severly overloaded, vs the front axel. BUT, I usually find that the axels are pretty well split even on weight.
Could be that the rear axels bearings were tighted up too much too.
As mentioned, if tires are hot, could be under inflation of those two tires.

It's a horse trailer...
The O.P. doesn't say how many horses it holds or where they were at the time, but it seems to me like there can't be too many options as far as cargo distribution is concerned- or are there???
On edit:
Come to think of it...it's a gooseneck unit, which could be pretty big.
If there's just hay and tack up front and a couple thousand pounds of horses in the back, improper weight distribution/excessive load at the rear could well be the problem.

another thing to check; does the trailer sit at an angle with the front higher than the rear of it? The truck could sit higher than the gooseneck was designed for.

It's a 3 horse slant with dressing room up front/gooseneck area.
I was hauling one Belgian draft horse, weighing 2000 lbs, I guess she's considered cargo 
Can't find a code on the tire.

Francesca,
Not sure that even in the example you uses, that a trailer with tandems would have this happen. Usually it takes a nose up or down to get on or the other axels from the times I have been able to weight them seperate to see what I would call major wt differences. To me this would be in the 500+lb range, usually I see no more than 20 or 40 lbs, as that is the scale measure split. It has not mattered if this is my RV trailer, or one of my equipment trailers.

was the horse in the front stall or the one at the back of the trailer? 2000 pounds is a lot sitting on the end of a trailer.
So wheres the tap on a draft horse go anyhow?
