I'm no expert, but when we were initially looking at TM's it was apparent that some of them had tire problems. The more I followed up, the more it appeared that the 2-axle models had more problems than the single-axle models; just the opposite of what might normally be expected.

Then one of the TM old-timers told me that it was because the original 2-axle tires had fewer plys. He said that among his friends and acquaintances in the Colorado area, where there are a number of trailers and at least one very knowledgable dealer, that the heavier ply tires had solved most of the problems.

I'm not sure if this is the correct answer for any or all of the TM's, but it is a logical answer and is consistent with the answer that was proven (by an exhaustive testing process) for one of the business jets a few years back.
