I was the original poster and I was trying to figure out my trailer weight in replation to the load range C tires I had.
The final conclusion I found was that the tires are very closely matched with my trailer and weight. Further I have found out that maintaining COLD air pressure is critical to all tires no matter who makes them.
If you check a hot tire pressure it should be higher than cold air pressure and you should never lower hot air pressure down (such as 60 psi on a 50psi tire) to the cold air pressure of 50 psi.
In reality you are lowering the tire pressure to 40 PSI cold.
I have read that it is normal for a hot tire to increase the tire pressure 10 psi more than rated. This is built into the tires cold air pressure.
Hopefully this is understandable. I get it.
Make sure you check your tires before and during your trip and always whent he tire is cold and not hot.
Another statment I think is worthy is that if you are traveling and you stop at a rest stop you should feel your tires tread. They should not be extremely hot. They could be warm but not extrememly hot.
That is possible in Arizona summers. Air temperature of 115 degrees and the asphalt temp of 150 degress.
