I was hopeful someone would disagree with me that this tire was made the first week of December 1999-1989 or1979 My Coach is a 2001 American Dream. I bought it a few years ago and everyone told me the tires were like new and wouldn't have to worry about them. So I didn't. Had them inspected last year and mechanic said I could get another year at least out of them

Herman no these are the date codes DOT FVEA-AU2 X  489 this was the only tire I can get the code for on the back Right outside duelly. The Right side front is  FVEA CN8 X 2511 Therefore I am waiting to crawl under to see what the codes are for the others.
