I should already know this, but the nuances are escaping me.
The tires on my NT show the following date codes.
Front: 0117
Rear: 4619
If I'm correct, that yields a manufacture date of January 2017 for the front, and ... April or June of 2019 for the rear?
Michelin Pilot Road 4's, by the way. They show no signs of dry rot or cracking. The front holds air and doesn't lose even a pound over a week. The rear needs a shot of O2 once in a while.
Other than the age making me nervous they seem fine. That said, new rubber is a top priority as I tend (or at least attempt) to wear the side-sipes as much as I do the centerline of the tread.
Thanks in advance,
Rick
