I have learned a lot about proper TT tire care over the years of reading th threads on this forum. I don't believe this is as much of a tire manufacturer debate as it is about proper tire care and making sure you are not overloading the tire. I'm not a tire expert by any stretch. I learned the hard way about not overspeeding and thus overheating a tire. On an old viking pop-up when in a hurry i was running 70mph on a road that was just ground down to be resurfaced. The right side blew but thankfully didn't do major damage. I didn't have a spare with me and learned another lesson the hard way.
I run Hercules power str's, radials in load range D which is more than i need for my rig weight wise but i like the added margin. I air them up to the 65psi max before leaving on a trip, i keep them covered, and i run 60 on the highway, and I'm very careful not to curb them.
Even with all that i could still have a failure. Any mass produced item can have an issue. I do agree lt tires are better quality. But what i have works for me for now. At least I've graduated from bias - ply.
