2002 Thor Aerolite Problems, complaints & recalls

who informed me that these tires were over two years old and they couldn't do any thing for me. They said this tire was made by good year and I could contact them and see if they would do anything. I called goodyear and was told they would pay for any damage to my trailer the tire had done, if I had kept the old tire. They said they would even pick up the old tire at the dealer where I had left it. No one ever mentioned this when I was buying replacement tires. I called the dealer but they had already disposed of the old tires. I was on vacation for two and a half months in florida so the old tires were gone. I still have one of the tires left. Because I don''t trust them, this tire will never be used on the road. I have this tire in my garage if goodyear would like it back. Also, I have one tire under the trailer used for a spare. I have already had my trailer fixed with an insurance claim, but had to pay a 100 dollar deductible. I don''t understand why goodyear would pay for damages but not pay for replacing these tires. I hope these marathon tires are better than I had, but they still worry me since goodyear made both tire brands. I believe carlisle tires or goodyear tires owe me the money for the 4 tires I replaced, and my deductible. Plus they should replace the spare. Here is some more info that was on the one remaining tire I kept. (111229 Dot dbhbh12 cr9592-1 drcd75-a-ees) any help you can give me would be greatly appreciated.
