I had a blow out this summer - going 50mph on an uphill climb. Tire pressure was correct, but it split from rim to rim.
When we pulled into Les Schwab Tires in Shasta, CA the trailer was jacked up and the mechanic spun the tires. The outside (facing outward) side walls were fine, the back of my tires were bumps and bulges all over - which I couldn't/didn't see from the outside when I pulled the tires and greased the bearings before the trip. If I had seen it before, I could have gone through the hassle of working with the manufacturer (Keystone) to get the tires swapped as a warranty issue.
All four tires had the same defect and I replaced all four while I was there. I did try to replace them with LT's but they wouldn't do it for some "insurance" reason. If I wanted to move the trailer off their property and bring the tires up to them one at a time they would have done the swap. I opted for the ST's because I was on a trip and needed to get somewhere that night.
That being said, my previous TT had the Towmax tires and as long as they were inflated correctly, I didn't have any issues.
I learned a valuable lesson - how to check the tires for manufacturer defects even though they were brand new.
Last item. Get your tires balanced. Since the new ones are on, when I brake, I don't feel that "vibration" I felt in the past. Beside the longevity of your bearings the lack of vibration is a great thing!
