Cause of 14" tire failures
I don't know that I've seen this specifically noted anywhere, but it seems to me that the load rating of the 14" Marathon's was just marginal for a 2720. Could that explain the seemingly large number of blowouts on that model/tire size? If you load up a 2720 (or even a 2619) it could put the total weight over the limit. And even a properly inflated tire at reasonable speed would be subject to failure. And it might explain the relative lack of blowouts on 3023 and 3124 models - which have a D rated 15" tire from the factory?
I don't have the figures handy here, but I know that the D load range for a 15" tire is >2600 lbs - which puts the total way over 5000 lbs for the trailer. You'd have to load up a 3124 pretty heavy to reach that. (My 3124 is 4240 lbs with close to camping ready status).
Just a thought. Other may have differing opinions.
