LT Tire vs ST Tire
I assumed I wanted ST Tires for my camper and some people are telling me to go with LT Tires. Now I'm confused, and guess I shouldn't assume.

LT proponents like to point out the higher testing standards applied to those tires, and rightfully so. No ST tires are tested in the same way. What would be the point in testing tires for conditions they are not intended for?
By the same token, there is no test data to indicate LT tires make good trailer tires. They aren't designed for it, therefor are not tested for it.
The majority of all reported tire failures are attributed to under-inflation by all official studies.
Another truth is that trailer manufacturers outfit their units with tires that could be characterized as "under-rated". One point that seems to be universally agreed on is that if you have load range 'C' tires, you should move to load range 'D' tires. Also, when you get new tires, ensure the valve stems are steel.
A Tire Pressure Monitoring System is also a wise investment. Not only does it allow you to continuously monitor air pressure, with alarms for under and over inflation, it also monitors the tire temperatures. IMO a much more relevant indicator of tire condition.
Trailers are not a part of the testing in any way.
The same machines test both tire types... The standards are just more extreme for the LT tires.
