I have always heard go by DOT date, not service date. DOT date puts them at almost 5 years. Chassis date is about 4 years and motorhome build date is just a little more than 3 years. I don't know when the tires would have been put on or how Michelin or Winnebago stores them. I hear a lot of tires were sitting in inventory after the recession hit in 2008.

There are no laws in the US governing tire age. If you look at research the industry has done in various countries you will see that the following statement is now broadly accepted;
"In October 2005 Bridgestone/Firestone broke ranks with other tire makers and issued a “Technical Bulletin” to its dealers advising them that tires should be inspected after 5 years and replaced after 10 years – “even when tires appear to be usable from their external appearance or the tread depth may not have reached the minimum wear out.” Michelin and Continental issued similar bulletins in February 2006. Hankook joined the chorus in 2009. Most – including Bridgestone/Firestone – were actually recommending a 6-year shelf life for tires, because the tiremakers’ tire age warnings defaulted to the individual vehicle manufacturers’ recommendations. Automakers had, by and large, opted for a six-year tire age recommendation."
