Anyone else going through trailer tires this summer?

I’ve had many blow outs and found under inflated and over speed is what kills tires. Age is really important. Drive them around at least once a month and keep them covered when not in use really helps.Hard to keep from heating up when it’s been a real summer. I switched to E ply tires where I can and go as tall as possible to keep the revs down. Pulling over every so many hours and letting them cool while I grab an iced coffee or visit the facilities also helps.
