Thanks all for the discussion!
LT's are being installed tomorrow am. Before the trip home. I think this is a good call in this specific case. They will be under loaded and run at max pressure. Again,,,, the ST tire solution is not working, and I really believe it is a wide spread problem that needs to be addressed in the industry....
#1 the tires are not up to the job.
#2 the RV's are not constructed to survive a tire failure without significant damage.
I now run a Class A, however for years prior I experienced this myself, tried multiple brands on a tri axle trailer, and had 6 tire failures in probably 40,000 miles. Maxiss, and other brands were tried, I never had tires on the trailer owned from 2004 to 2015 older than 2 1/2 years as each time one failed,,,, I replaced them all due to fear of more significant damage. I ran a tpms, was religious about checking pressure, and never had a clue till the big bang,,,,, except for when my son saw the tell tale wobble from behind. I did not have another option on my tri axle as it ran 15" tires.
Lots of discussion here about sidewall. My failures and my son-inlaws in this thread were belts in the tread failing. If you examine his failing tire at this moment on his trailer,,,, the tread has a wave in it... it will soon come apart.
