Followup for anyone interested.
I did go with the Carlile tires. Got them from Indy Tire in Fishers, Indiana and replaced all 4.
Talked to the folks at Indy Tire and they examined the one faulty tire. I had two different guys give me their opinion. Both agreed there was nothing wrong with the trailer alignment.
Both agreed the side cords has broken down on the side wall of the tire, probably as a result of turning too sharp causing the side stress on the rear tire. One of them suggested over and under inflation, with the side motion could have caused the side wall stress. I've been carrying 55 pounds in my TT tires. I'm thinking they might have been under inflated, and I just wasn't watching for tread wear on that side of the trailer as I usually do not cover the tires on side when home, since it's always on the shade side and not exposed to the sun. And another guy pointed out the bad tire was beginning to show signs of dry rot, which really surprised me. The other 3 did not have any signs. So, looks like it was just a little bit of an inferior tire compared to the other 3.
New tires have a max PSI of 80. He asked where I wanted the PSI, I told him 65. He said watch for early signs of wear. If wearing in the middle, too much PSI, if on the edges, too little PSI.
So, after I get home tonight, I'm off to Wall Mart for some shopping with my wife and going to pick up a simple tire tread gauge so I can track what's happening on all 4 tires for a while. We still have many week-end trips planned for the remained of this year, and Christmas in South Carolina this year, so I'll be rolling the miles.
Anyway, I though everyone would appreciate a follow up, and it gives me a little better feeling knowing the tire just reached the end of it's life. I'm not complaining, those were the original tires that came with the camper and I'm sure I've rolled a good 20,000-25,000 miles on them in all kinds of weather conditions. Not bad for 3 years on the original Chinese tires to say the least!
And oh, the guys at Indy Tire said the newer Carliles are definitely improved over the old ones. (And are actually $10 less per tire too.) They evidently sell a lot of Carliles for TT's and 5er's based on what we talked about.
So, I'm a "happy camper" again! Ready to hit the road again!
