Tire pressure & too many blowouts

Hi, i would agree on your point in general, however with new tires two days old on my first trip I blew a tire after 80 miles. On the second trip two months later after 60 miles. The other two times were a couple years apart but I still don't thinks age was an issue. The camper is stored inside my barn and on blocks when not used. Id say without a doubt the tire pressure was the culprit.
