Thanks TRIPLE8 for the replies. But.....I have to say that the way this thread reads plays out a scenario which never happened. Reading from the start of the thread, it looks like you have a triple axle trailer with E rated Maxxis tires that cant hold up to the weight you're placing on them, even though that weight is well below their rated capacity. Thats obviously not the case so, with that said, I'm now doubting your "tire guys" diagnosis of your tire problem.
Dont get me wrong here by saying that either, and you're more than welcome without out any negative judgement on my part to choose LT tires over ST tires. I actually commend someone able to afford the money for the LT conversion, but calling a spade a spade is important for other people researching ST tire brands. If the Maxxis tires truly weren't holding up to your needs based on an accurate situation then OK, but the story doesn't seem to read like that.
