Heat which is generated by running low tire pressures is the usual culprit. Most folks do not think to check their seldom used trailer tire presures.... I do EVERY time I use a trailer.
I run 80 psi in my homebuilt double JetSki trailer tires which are loaded within 50 lbs of the max weight rating. When I first used this setup at highway speeds on a 90 degree summer day, I stopped often to check tire temps with a digital thermometer... temps never climbed above about 100 degrees.
This particular set of tires were left overs I brought from work 15 years ago when we built a custom tire mounting machine for a customer. They had been been in my attic for over 10 years before I put them into service several years ago on my JetSki trailer. They will not get replaced until they show signs of dry rot cracking on the sidewalls.
