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.
